Configuring Siemens KTP700 HMI with TIA Portal WinCC Basic

KTP700 HMI Identification and Panel Family

The first engineering decision when commissioning a SIMATIC KTP700 is identifying which member of the panel family has been purchased. Siemens markets two parallel KTP700 product lines under the SIMATIC HMI portfolio: the KTP700 Basic (key/touch, 7-inch, basic functionality) and the KTP700 Comfort (key/touch, 7-inch, comfort functionality). Both are 7-inch widescreen devices with 800 x 480 pixel resolution and 16 million colors, but they target different application classes, support different firmware feature sets, and are programmed with different editions of WinCC in TIA Portal.

Identify the panel by reading the order number (MLFB) on the rating label on the back of the device. Common order numbers include:

For a first-time HMI user migrating from physical selector switches on a LOGO! 8 (6ED1052-xxx08-0BA1 or later base module) to a touch interface, the most common configuration is the KTP700 Basic driven by WinCC Basic inside TIA Portal. Cross-reference the part number at the Siemens Industry Online Support portal under Product Support to confirm the firmware/engineering tool combination before installation.

WinCC Software Tiers and Licensing

TIA Portal ships in several discrete WinCC editions, each with a different license entitlement and runtime scope:

The Basic edition is sufficient for replacing hard-wired selector switches with on-screen buttons, indicators, and numeric input fields. It supports up to 100 tags (upgradeable via Power Pack 6AV2181-8AB10-0AX0 to 256 / 500 / 2048) and includes the standard graphics library plus vector-based basic objects.

The historical 6AV2100-0AA06-0AH5 license is valid for TIA Portal V11 through V16 and grants authorization for WinCC Basic engineering of Basic Panels. For users on TIA Portal V17 or later, verify the current license at the time of purchase; Siemens periodically retires older MLFBs and substitutes the current TIA Portal version's license part.

TIA Portal Version Compatibility Matrix

Cross-firmware compatibility is strict on Basic Panels. The HMI's runtime firmware revision must be supported by the TIA Portal you install on the engineering PC. Mismatches cause the download to fail with diagnostic buffer entries of the form "Firmware version of the device is not supported" or "Image version Vxx.xx.xx is too old/new".

Best practice: update the panel image with the SIMATIC ProSave tool and the latest HSP (Hardware Support Package) to the revision supported by your TIA Portal before commissioning. The latest HSP for the Basic Panel line is distributed via the TIA Portal Support Packages channel.

Prerequisites

Before opening TIA Portal for the first time, verify the following:

1. PC hardware: Multi-core x64 CPU, 8 GB RAM minimum (16 GB recommended), 20 GB free disk for TIA V16 install plus working folders.
2. Operating system: Windows 10 (64-bit) Pro/Enterprise 1909 or later, or Windows Server 2016/2019. TIA V16 is the last release to support Windows 7 SP1.
3. LOGO! 8 base module: 6ED1052-1MD08-0BA1 (12/24 RCE) or 6ED1052-1CC08-0BA1 (24 VCE) or later with firmware FS04 or higher. The Ethernet port on the base module is required for S7 communication with the KTP700.
4. Network: Standard Cat5e or better patch cables, a small managed/unmanaged Ethernet switch, or a direct crossover-style link (modern NICs auto-negotiate).
5. License USB stick or an active Software Center license server for WinCC Basic.
6. Siemens Product Support account (free registration) at support.industry.siemens.com for downloading the trial bundle and HSPs.

Installing TIA Portal and WinCC Basic

1. Run the TIA Portal V16 setup executable SIMATIC_TIA_Portal_V16.exe as administrator.
2. Accept the licensing agreement and choose User-defined installation.
3. On the Product selection screen, expand SIMATIC TIA Portal > SIMATIC STEP 7 Basic and SIMATIC WinCC Basic. Deselect any Comfort/Advanced/Professional components unless they are licensed.
4. Confirm the installation path (default C:\Program Files\Siemens\Automation) and complete the wizard. Restart the PC when prompted.
5. Launch the Automation License Manager and transfer the WinCC Basic license 6AV2100-0AA06-0AH5 from the USB stick or licensed container to the local or server license pool.
6. Open TIA Portal and select Start > First Steps > Install Support Packages. Install the latest HSP for LOGO! 8 and the KTP700 Basic line.

Creating a Project and Adding the KTP700

1. Open TIA Portal. Select Create new project, name it (e.g., LOGO8_HMI_Control), and set the project path.
2. In the project tree, double-click Add new device. Navigate to HMI > SIMATIC Basic Panel > 7" > KTP700 Basic and select the exact MLFB matching the rating plate (e.g., 6AV2123-2GB03-0AX0).
3. Open the HMI's Device configuration and confirm the default PROFINET interface settings: IP 192.168.0.10, subnet mask 255.255.255.0. Adjust to match the plant network plan. The KTP700 has a single PROFINET (Ethernet) port only — no PROFIBUS option.
4. Click Add new device again. This time, select PLC > LOGO! > LOGO! 8 matching the base module revision.
5. In the LOGO! 8 device configuration, set its IP address to 192.168.0.1 with subnet 255.255.255.0. Enable Permit PUT/GET communication under Properties > Protection & Security (mandatory for HMI S7 access to LOGO! data blocks).

TIA Portal will automatically create a Devices & Networks editor view where the LOGO! 8 and the KTP700 are placed on the same PROFINET subnet. Draw a connection between the two Ethernet ports; the resulting PROFINET IO relationship is what enables the HMI to read/write LOGO! process tags.

Establishing LOGO! 8 to KTP700 Communication

The LOGO! 8 base module does not expose symbolic tag names the way an S7-300/1500 CPU does. The HMI addresses the LOGO! 8's input, output, flag, and DB/VB image areas using absolute memory addresses. The relevant address ranges (LOGO! 8 firmware FS04 and higher):

In TIA Portal's HMI tag table, define tags as follows:

Name           : Pump1_Run
Data type      : Bool
Connection     : LOGO8_Connection (S7-200 compatible driver)
Address        : %VB1000.0
Acquisition    : Cyclic 1 s

Use the S7-200 protocol in the HMI connection dialog rather than S7-300/400 — the LOGO! 8 base module emulates the S7-200 communication primitive. Set the Access Point to S7ONLINE and the TSAP to 01.01 for the local and 01.00 for the partner. Rack/slot remain at 0/1 (LOGO! 8 is a compact single-slot device).

Configuring Tags and Pointers

For screen-level logic such as showing a numeric setpoint, the HMI tag setpoint can be tied directly to a LOGO! 8 variable. For pointer-style navigation between screens (e.g., to a maintenance page when a fault is active), use the Area pointer mechanism under HMI tags > Connections > Area pointers:

After the area pointers are configured, a single LOGO! 8 program line such as Q1 := M3 (Screen number = 3) can route the operator to a maintenance screen automatically when a fault condition is met.

Designing the Operator Screen Layout

Open HMI > Screens > Add new screen and rename the default root screen to Process_Overview. Use the Tools palette on the right edge to place objects:

1. Replace each physical switch with a button: drag Elements > Button to the canvas. In its Properties > Events > Press dialog, configure a Set bit action on tag Pump1_Start at address %VB1000.0 (output to LOGO! 8). Optionally, a Reset bit action on Release replicates a maintained-contact switch; for true latching, set the bit on Press only and let LOGO! 8 logic handle the seal-in.
2. Add a status indicator: drop a Circular indicator or Bar element. Bind its Value property to tag Pump1_Run at address %VB0.0 (LOGO! 8 input feedback). Use a green fill range and a red low range for instant readability.
3. Numeric input for setpoints: drop a IO field on the canvas, set the Process value tag to Setpoint_Speed, and define the data type as Int with limits 0-1000. The PLC-side address might be %VW3050 on the LOGO! 8 data block.
4. Screen navigation: place a Button, set its Press event to ActivateScreen, and select Maintenance from the screen list. Optional ChangePassword events can restrict access.
5. Alarm banner: under HMI > Alarm logs > Discrete alarms, add a tag-bound alarm (e.g., High temperature at %VB2.0). Tie it to a configured Alarm view object on the main screen.

For visualization of the digital switches that the user is replacing, a typical first screen might contain three buttons in a horizontal row: Start Pump 1, Stop Pump 1, and Reset Fault. Above each button, a corresponding lamp object indicates the active state. This preserves the muscle memory of the original hard-wired switch panel while adding the benefits of touch control and centralization.

Downloading and Verifying the Project

1. Compile the project: select the LOGO! 8 first and click Compile > Hardware and software (rebuild all). Repeat for the HMI.
2. Connect the engineering PC to the same Ethernet switch as the LOGO! 8 and KTP700. Verify the PC's IP is in the same subnet (e.g., 192.168.0.100).
3. Right-click the LOGO! 8 device → Download to device > Hardware and software. Select the correct NIC under PG/PC interface. Accept the certificate if shown.
4. Right-click the KTP700 device → Download to device > Software (all). Choose the Overwrite all option to clear any existing project on the panel.
5. The KTP700 will reboot and display the configured root screen. Touch a button; the corresponding LOGO! 8 output should energize and the status indicator should change color.
6. Use the Online > Go online function on the HMI tags to monitor tag values in real time and confirm cyclic data exchange.

Troubleshooting Common Errors

Migration Checklist From Hard-Wired Switches to KTP700

1. Document each existing switch's function, label, and the LOGO! 8 input/output address it currently drives.
2. Map each switch to a corresponding HMI button and lamp object. Reserve one tag per signal.
3. Decide which signals need operator-setpoint entry (numeric IO field) versus simple on/off.
4. Define which screen will be the home page and the navigation hierarchy (e.g., Process → Maintenance → Diagnostics).
5. Plan operator authorization: WinCC Basic supports user groups and password-based screen protection; use these to lock maintenance screens behind a login.
6. After commissioning, archive the TIA Portal project to a network share; future panel swaps are one download away.

Notes on Non-Siemens Alternatives

For applications where the LOGO! 8 is paired with a non-Siemens HMI, the configuration software differs by manufacturer. For example, Schneider Electric's Harmony HMI panel line is programmed with the EcoStruxure Operator Terminal Expert tool (formerly Vijeo Designer) and supports Modbus TCP drivers that can talk directly to the LOGO! 8 base module's Modbus server. Refer to the Schneider Electric HMI Configuration Software product category for current tool versions and panel compatibility. The selection of WinCC Basic, Vijeo Designer, GT Works, or EasyBuilder Pro is dictated entirely by the HMI hardware vendor and must be matched 1:1 to the panel MLFB.
