SIMATIC Field PG Specifications: M5 and M6 Programming Devices

1. Overview of the SIMATIC Field PG Platform

The SIMATIC Field PG is Siemens' purpose-built industrial notebook platform for mobile commissioning, online diagnostics, firmware updates, and project transfer on SIMATIC controllers. Unlike commercial or even semi-rugged laptops, every Field PG leaves the factory with a Siemens-signed operating system image, a SIMATIC-licensed engineering toolchain, an on-board MPI/PROFIBUS CP, and a SIMATIC Memory Card reader that standard PCs physically lack. Two active generations coexist in the installed base today: the SIMATIC Field PG M5 and the SIMATIC Field PG M6. Both are full-performance rugged notebooks that meet industrial mechanical and EMC requirements and that integrate directly with SIMATIC NET, TIA Portal, and legacy STEP 5/STEP 7 environments without third-party hardware.

The official product landing page, SIMATIC Field PG – Rugged Programming Device, lists the active configurator and the release notes for the current M generation. The M5 datasheet, SIMATIC Field PG M5 datasheet (DFFA-B10336-00-7600, PDF), and the M6 operating instructions, SIMATIC Field PG M6 operating instructions (article 109761660, PDF), are the canonical references for exact part numbers, environmental ratings, and shipped software builds. Always verify the specific configuration and order code against these documents before specifying or quoting.

2. Engineering Advantages Over Generic Industrial Laptops

The principal engineering advantage of a SIMATIC Field PG over a third-party industrial laptop is integration depth. For an engineer who routinely migrates between cells, swaps firmware, or performs distributed I/O diagnostics, this integration is decisive. The defining capabilities are summarised below.

Built-in CP (Communications Processor) interface. The Field PG exposes RS-485 at a 9-pin Sub-D connector and supports MPI and PROFIBUS DP/FMS in PG mode. Maximum PROFIBUS bit rate is 12 Mbit/s (the PROFIBUS standard upper limit); MPI is supported to 187.5 kbit/s. No external USB-to-MPI converter is required. A standard laptop would require a Siemens PC adapter (6GK1571-1BA00 USB A2, or the legacy 6GK1571-0BA00 COM-port version) and the corresponding SIMATIC NET PC driver package, which on a non-validated image often triggers Windows driver-signing prompts and PG/PC interface conflicts that can block online access for several minutes per CPU.

SIMATIC Memory Card reader. The Field PG accepts the SD-format cards used by S7-300 (CPU 31x), S7-400 (CPU 41x), S7-1500 (CPU 15xx), ET 200S, and ET 200SP CPUs. A generic laptop requires an external USB SD reader and the TIA Portal "Card Reader/USB memory card" plugin to write the project to the card, and the workflow is more error-prone when the reader is not part of the validated hardware stack.

Pre-installed, device-bound engineering toolchain. Both the M5 and M6 ship with TIA Portal (STEP 7 Professional, WinCC Professional/Comfort, Startdrive for SINAMICS, SIMATIC NET PC) pre-installed and pre-activated. The license is bound to the device hardware fingerprint via the Automation License Manager, eliminating license transfers when the engineer moves between machines.

Validated driver stack. The image includes the SIMATIC NET PC software that exposes the on-board CP to TIA Portal's "Set PG/PC interface" dialog. This removes the install-and-reboot cycle required to commission a CP on a generic laptop and avoids the recurring Windows update interactions that sometimes reset CP bindings on third-party hardware.

Mechanically reinforced chassis. Reinforced housings, plant-floor keyboards, and shock-mounted storage are validated to industrial vibration profiles. The M6 operating instructions, Field PG M6 operating instructions (PDF), list the operating temperature, drop, and shock envelopes; the M5 datasheet, Field PG M5 datasheet (PDF), lists the equivalent M5 values.

3. SIMATIC Field PG M5 Specifications

The M5 generation is documented in the official Siemens datasheet (DFFA-B10336-00-7600) and is positioned for mobile applications in industrial plants with a combination of ruggedized chassis and pre-installed TIA Portal engineering software. The headline parameters (as listed in the datasheet) are:

Refer to the official SIMATIC Field PG M5 datasheet (PDF) for full configuration options, part numbers, and the exact operating system/build permutations shipped at order entry. The M5 datasheet is the authoritative source for environmental ratings, electrical ratings, and the list of countries/certifications covered by the active release.

4. SIMATIC Field PG M6 Specifications

The M6 supersedes the M5 and is documented in the Field PG M6 operating instructions (Siemens support article 109761660). The M6 retains the M5's on-board CP and SIMATIC Memory Card reader while updating the industrial design, processor class, and shipped TIA Portal version.

Full mechanical, EMC, and environmental ratings are listed in the Field PG M6 operating instructions (PDF). Always verify the specific configuration against the Siemens online configurator (SIMATIC IPC MD 57A) before ordering, because CPU class, OS build, and engineering software options are selected at order entry and cannot be retrofitted without re-imaging.

5. Communication Interfaces and Protocol Support

The defining feature of a Field PG is its on-board industrial bus stack. The CP interface typically exposes the following logical channels.

MPI (Multi-Point Interface). RS-485, up to 187.5 kbit/s. Used for S7-300/400 firmware download, online diagnostics, and PG-to-PLC routing through a SIMATIC NET gateway. TIA Portal's "Accessible nodes" function uses the MPI bus scan to find stations on the segment. The MPI connector is shared with PROFIBUS on a 9-pin Sub-D; pin 3 is data B (green wire convention), pin 8 is data A (red wire convention) per PROFIBUS IEC 61158/61784.

PROFIBUS DP / FMS. RS-485, up to 12 Mbit/s. Supports class-2 master (PG) functions, including distributed I/O diagnostics on ET 200 stations and online firmware update on PROFIBUS slaves. TIA Portal uses the integrated CP through the PG/PC interface drop-down. Common commissioning baud rates are 1.5 Mbit/s (default on many S7-300 MPI/DP ports) and 187.5 kbit/s when running through a non-terminated or long segment.

PROFINET (Ethernet). 100 Mbit/s copper (RJ-45). Used for S7-1200/1500/ET 200SP download, online, and trace functions. The Field PG's Ethernet port is also the default for connecting to the plant LAN for multi-user TIA Portal projects, the TIA Portal Cloud Connector, and Teamcenter Engineering integration. PROFINET discovery relies on LLDP and DCP; ensure the Windows firewall on the Field PG allows UDP 34964 (PN DCP) and the discovery ports.

SIMATIC Memory Card. Native reader for SD-format S7 program cards. Used for firmware updates, project transfer without an online connection, and HMI panel restore. The same slot accepts the SD card used by Comfort Panels and Unified Comfort Panels for image backup and restore.

The integrated CP removes the requirement for a Siemens PC adapter (for example 6GK1571-1BA00 USB A2) on every visit, although the PC adapter remains a useful fallback for machines that lack a free USB port, where a PG must communicate with a station whose MPI/DP connector is in a difficult-to-reach location, or where the on-board CP is in use by another engineer on the same segment.

6. Pre-Installed Engineering Software Stack

Each Field PG ships with a Siemens-signed disk image. The default toolchain is built around TIA Portal, with legacy components retained for brownfield work.

• TIA Portal (STEP 7 Professional, WinCC Professional/Comfort, Startdrive for SINAMICS, SIMATIC Energy Suite on supported images).
• SIMATIC NET PC software for CP 5611/CP 5612/CP 5622 configuration and for exposing the on-board CP to TIA Portal's "Set PG/PC interface" dialog.
• STEP 5 / STEP 7 legacy compatibility (M5 and earlier M6 images, depending on the engineering order code).
• S7-PLCSIM for offline simulation of S7-300/400/1200/1500 logic.
• Automation License Manager for device-bound license activation.

The license key is bound to the device, so the engineering toolset cannot be transferred to a non-Field-PG laptop without re-licensing through the Automation License Manager. This guarantees that a service engineer arriving on site with a Field PG always has a complete, signed, and activated toolchain regardless of where the laptop was last used.

7. SIMATIC Memory Card Workflows

The integrated SIMATIC memory card slot accepts the same SD form factor used by S7-300 (CPU 31x), S7-400 (CPU 41x), S7-1500 (CPU 15xx), and ET 200S/SP CPUs. Typical field workflows include project transfer, firmware update, and panel image restore.

Project transfer without online connection.

1. Insert the project card into the Field PG's card reader.
2. Open TIA Portal → Project → Card Reader/USB memory card → "Write to memory card".
3. Select the target card type and confirm the CPU article number.
4. Remove the card and insert it into the target CPU. Power the CPU up; the CPU loads from card on stop-to-run transition.

Firmware update via card. For an S7-1500 CPU that will not boot (e.g. firmware corruption), the recommended recovery is to write a fresh firmware file plus a minimal project to the SIMATIC memory card using the Field PG, insert the card into the unpowered CPU, then power up. The CPU reads the firmware from the card and recovers. This is the only viable recovery path when the online Ethernet/MPI channel is unavailable.

HMI panel image restore. Comfort Panels and Unified Comfort Panels accept a SIMATIC-style SD card containing a complete image (.img) created from the panel's ProSave tool. Use the Field PG's card reader to write the .img file to the card, then insert the card into the panel and trigger the restore from the panel's service menu.

These workflows allow firmware upgrades and project migration without a working online Ethernet/MPI/PROFIBUS connection, which is critical for commissioning in isolated cells, retrofit projects, and after-hours service calls.

8. Network Topology and Routing

The Field PG acts as a class-2 master on MPI/PROFIBUS and as an engineering station on PROFINET. A typical commissioning topology is shown below.

Through the on-board CP, the Field PG can route between subnets when SIMATIC NET PG mode is enabled. For example, an engineer on PROFINET can reach a PROFIBUS slave through a SIMATIC PN/PN coupler or an IE/PB Link PN IO, with routing configured in TIA Portal's "Accessible nodes" view. Activate "Use router/subnet transition" in the online dialog and verify that the gateway CPU has a routable S7 connection in its project.

9. Accessory Catalog

Siemens publishes the SIMATIC PG accessory portfolio in the Siemens A&D Mall (mall.automation.siemens.com) under "SIMATIC Automation System → Programming Devices → Field PG M". Typical accessories include:

Order part numbers vary by active release; confirm against the current Mall catalog before specifying. The Mall is reachable via SIMATIC Field PG – Rugged Programming Device.

10. Side-by-Side Comparison: Field PG M5 vs M6 vs Generic Industrial Laptop

11. Field Commissioning Workflow

Use the following sequence when connecting a Field PG to a SIMATIC station for the first time.

1. Power on the Field PG. Verify the TIA Portal version and language match the target plant's project baseline. Open "Help → About TIA Portal" and record the build number.
2. Connect the MPI/PROFIBUS cable between the PG's CP port and the CPU's MPI/DP port. Confirm the green link LED on the 9-pin Sub-D connector. For PROFINET, connect the RJ-45 to the CPU's PROFINET port and verify the link/speed LEDs.
3. Launch TIA Portal, open the project, and choose "Go online → PG/PC interface → select the integrated CP" at the appropriate baud rate (default MPI 187.5 kbit/s, default PROFIBUS 1.5 Mbit/s, default PROFINET 100 Mbit/s full duplex).
4. Click "Accessible nodes" or "Start search" in the online dialog. Verify the device name and IP/DP address match the project's hardware configuration.
5. Download the project (or run "Compare offline/online") to confirm consistent state before any change. For an S7-1500, also run "Download to device → Configure PG/PC interface" the first time to assign a temporary IP if the CPU is unconfigured.

12. TIA Portal Configuration for the On-Board CP

For the integrated CP to appear in TIA Portal's PG/PC interface list, the SIMATIC NET PC software on the Field PG must be installed and the CP must be bound to a SIMATIC NET access point. Typical steps:

1. Open "Set PG/PC interface" (Options → Set PG/PC interface).
2. Under "Interface parameterization used", select "S7ONLINE (STEP7) → [on-board CP]".
3. For PROFIBUS, set the transmission rate to "Auto" or to the segment baud rate. For PROFINET, leave the TCP/IP settings at default (DHCP off, link-local fallback if required).
4. Click "Diagnostics → Run" to verify the CP enumerates and that the driver status reports "OK".

If the on-board CP is greyed out or marked "not found", re-install SIMATIC NET PC from the recovery image and re-check in Device Manager that the CP device tree shows no warning triangle. On Windows 10 IoT Enterprise LTSC images, signed drivers are required; the Field PG image pre-installs these, so a generic Windows 10 image would also need the SIMATIC NET PC setup separately.

13. License and Image Management

Field PGs ship with a sealed disk image. Modifying the image (installing consumer anti-virus, swapping the OS, replacing the SSD with a non-approved part) is possible but voids the device-bound license agreement and may cause the Automation License Manager to reject the engineering toolset on next start. The Automation License Manager uses the device fingerprint derived from the CPU ID, motherboard serial, and storage device serial; changing any of these requires a license rehost.

For re-imaging, use only the Siemens recovery USB stick (see the accessory catalog). After recovery, the Automation License Manager restores the license keys against the new disk image automatically; if it does not, run "Rehost" in the License Manager and contact Siemens support with the license certificate number printed on the device's underside label.

14. Power, Display, and Ergonomics for Plant-Floor Use

Field PGs are designed for engineers who work partly at a desk, partly on the plant floor. The chassis typically offers:

• Anti-glare 15.6" display with high nit rating for direct sunlight and bright shop-floor lighting.
• Sealed or semi-sealed keyboard with drain channels for spilled coolant, oil, and water.
• Hot-swap-capable Li-Ion battery with charge-level indicators visible from the outside of the closed lid.
• Carry handle or strap points for two-handed field use.
• Docking connector for office-mode replication of USB, Ethernet, and external display.

Refer to the M6 operating instructions, Field PG M6 operating instructions (PDF), for the exact battery capacity, dock pinout, and charger specifications.

15. S7-PLCSIM and Offline Simulation on the Field PG

Because the engineering toolset is pre-installed, the Field PG can run S7-PLCSIM for offline simulation of S7-300/400/1200/1500 logic without a physical CPU. Workflow:

1. Open the project in TIA Portal.
2. Start S7-PLCSIM (Start → SIMATIC → S7-PLCSIM).
3. Select the simulated CPU type and start the simulation instance.
4. In TIA Portal, click "Go online" and select the PLCSIM instance as the PG/PC interface target.
5. Download the project to the simulated CPU; use the PLCSIM console to force inputs and observe outputs.

S7-PLCSIM is licensed separately. On Field PGs shipped with the TIA Portal bundle, the PLCSIM license is normally included; confirm in the Automation License Manager before commissioning simulation workflows.

16. HMI Panel Commissioning from the Field PG

The Field PG can act as a WinCC engineering station for Comfort Panels, Unified Comfort Panels, and WinCC Runtime Advanced/Professional panels. Typical workflow:

1. Connect the panel to the Field PG's PROFINET port (or use a switch if the panel is already on the plant network).
2. Assign a temporary IP to the panel using the panel's service menu (Settings → Network) if it is unconfigured.
3. In TIA Portal, open the HMI project, right-click the panel → "Transfer" → "Ethernet" → enter the panel's IP.
4. Start the transfer; the panel reboots into the new project. Use ProSave on the Field PG for image backup/restore via the SIMATIC memory card slot.

For panels that cannot be reached over Ethernet (e.g. damaged network port), use the SIMATIC memory card slot to load a previously generated image (.img) into the panel from the Field PG's card reader.

17. SINAMICS Startdrive Commissioning

For drive commissioning on SINAMICS G120, G120C, G120P, S120, and V90, TIA Portal's Startdrive plug-in is included on the Field PG. Workflow:

1. Open the project in TIA Portal, navigate to the SINAMICS drive device.
2. Click "Go online" → select the PROFINET or PROFIBUS interface to the drive.
3. Run the Startdrive commissioning wizard (motor data, encoder, control mode, ramp times, I/O configuration).
4. Use the control panel in Startdrive to jog the drive, verify direction, and check current draw before connecting to the load.

For firmware update of a SINAMICS control unit, use the Field PG's card reader or the online channel. The card-based path is preferred for production drives because it does not require an online interruption window.

18. Safety Acceptance Test (F-CPU) Workflow

When commissioning a fail-safe S7-1500F or S7-300F CPU, the Field PG can host the TIA Portal Safety acceptance test log. Procedure:

1. Open the F-CPU project, ensure the safety program is compiled and downloaded.
2. Navigate to "Safety → Acceptance test" in the project tree.
3. Run the test checklist; record check values for each safety function.
4. Print or export the acceptance test report to PDF and sign off per plant QA procedure.

Store the signed acceptance test report with the F-CPU's serial number and the Field PG's service log for traceability. The acceptance test must be re-run after every safety program change.

19. Multi-User and Teamcenter Integration

For plant-wide projects, the Field PG can connect to a TIA Portal multi-user server (TIA Portal Teamcenter Gateway or a plain TIA Portal multi-user server) on the plant LAN. Workflow:

1. Open TIA Portal → Project → "Open from server".
2. Enter the multi-user server address and authentication.
3. Check out the objects to be edited, make changes, and check back in.

For Teamcenter Engineering integration, install the TIA Portal Teamcenter Gateway on the multi-user server and use the Field PG as a TIA Portal client. The Field PG's validated OS image is a supported client platform.

20. OPC UA and Industrial Communication

The Field PG's TIA Portal can be used to configure OPC UA server interfaces on S7-1500 CPUs (firmware V2.0+), ET 200SP CPUs, and the IE/PB Link PN IO. Use the "OPC UA" node in the device properties of the PLC to define the server endpoint, security policy, and user authentication. Test the endpoint with the UA Expert client (a free download) on the Field PG before commissioning the HMI/SCADA consumer.

21. Backup and Recovery Strategies

For service continuity, configure the following on every Field PG:

• System image backup to an external USB drive after every TIA Portal update. Use the recovery tool from the recovery USB stick to create the image.
• TIA Portal project archive backup to a network share. Use TIA Portal → Project → Archive to bundle the project and its referenced global libraries into a single .zap file.
• Automation License Manager → "Backup license" to a USB stick. The backup allows rehosting onto a replacement device if the Field PG is damaged.

Test the recovery workflow at least annually; an unverified backup is not a backup.

22. Troubleshooting Matrix

23. Migration Notes: M4 → M5 → M6

When migrating from a previous Field PG generation, the engineering toolchain generally migrates without project rework: TIA Portal project files are versioned, and the Automation License Manager accepts the previous license certificate on a new device if the old device is decommissioned. Specific items to verify:

• The recovery USB stick is generation-specific; do not use an M4 stick on an M6.
• The 9-pin Sub-D pinout for MPI/PROFIBUS is identical across M4/M5/M6; existing 6XV1 830 cables remain usable.
• Older M4 images (Windows 7) cannot be ported to an M6 because the M6 ships with an industrial Windows 10 build only. Use the M5 if a Windows 7 image is required for legacy STEP 7 work.
• For STEP 5 work, retain the legacy M5 image; STEP 5 support is not always shipped on the M6 default image. Confirm at order entry.

24. Sourcing and Ordering

Siemens configures the Field PG through the SIMATIC IPC MD 57A page on siemens.com and prices it through the A&D Mall. Because the engineering software is bound to the device at build time, order the correct TIA Portal version, language, and STEP 5/STEP 7 option at order entry. The product page is at SIMATIC Field PG – Rugged Programming Device; the M6 manual is at Field PG M6 operating instructions; the M5 datasheet is at SIMATIC Field PG M5 datasheet. For local language variants, contact the regional Siemens sales office and reference the configured MLFB (order code) before issuing a purchase order.
