When you connect Easy Soft 5.1 Pro to EASY device 1, you can download programs to the other NET-connected EASY 8xx devices by switching to NET communication through the master and selecting the target programs in the download dialog. The PC communicates through device 1; selecting a program for device 3 does not mean the PC must connect to device 3 directly.
Does the PC reach the target device through the NET master?
Trace the transfer path in order: Easy Soft on the PC connects to device 1, the selected NET master; the master carries the NET communication to the selected target device. If the PC is still using local communication, the transfer is directed only at the locally connected device. Check the communication mode before troubleshooting the network path.
| Reading or setting | Expected for multi-device download | If different |
|---|---|---|
| Communication mode | NET | Switch from local to NET communication. |
| Device selected under Communication > Device > NET operation | Device 1, in the described configuration | Select the device the PC should connect through. |
| Program selection in download dialog | All, or the intended individual target programs | Select the target program(s) before confirming. |
What should you check before selecting programs?
Confirm the PC can communicate with the intended master over the existing connection, and that all four EASY 8xx devices are connected on NET. The described setup has all four devices connected and functioning. If the master is reachable but a target is absent from the download selection, recheck NET communication and the target device configuration before starting a transfer; selecting “All” cannot include a device Easy Soft does not present as available.
The path stops at different points depending on the symptom. If Easy Soft cannot communicate with device 1, check the PC-to-master connection and local/NET mode first. If the master connection works but a target program is not available for selection, check the NET device configuration and which devices are recognized. If the target is selectable but the transfer fails, record the software's actual error or status and check the communication path to that device; do not treat selecting the target as proof that its download completed.
How do you start the download through device 1?
- In Easy Soft 5.1 Pro, change communication from local to NET via the master.
- Open
Communication > Device > NET operationand select device 1 as the device the PC connects to. - Open
Communication > Program > Download. - In the selection dialog, choose the required program targets. Choose
Allwhen downloading every program; otherwise select only the intended devices. - Confirm with OK to start the program transfer.
The NET master is the communication route, not a substitution of device 1's program for device 3's. The dialog selection determines which device programs are transferred.
How do you verify the selected program reached its target?
Follow the transfer status for each selected program in Easy Soft and confirm that the download finishes for the intended device. If only some targets complete, identify the specific target whose transfer did not complete and recheck that device's NET communication rather than repeating an unverified “All” download. Where the application requires it, confirm the loaded program on the target device before returning the machine to operation.
What pitfalls cause a wrong or incomplete transfer?
| Pitfall | Effect | Correction |
|---|---|---|
| Leaving communication in local mode | PC is not using the NET path through the master | Switch to NET communication first. |
| Selecting the wrong NET device for the PC connection | The intended master route is not selected | Set device 1 in the described setup, or choose the appropriate master for the actual network. |
| Not selecting every intended target | One or more programs are omitted | Review the download dialog; select All for every program or the precise target set. |
| Assuming OK proves every download succeeded | Transfer initiation is confused with completion | Check completion status target by target. |
Can I download device 3's program while connected through device 1?
Can I download device 3's program while connected through device 1?
Yes. Set communication to NET through the master, select device 1 as the PC connection device, then select the intended program target in the download dialog.
Does the PC need to connect directly to every EASY 8xx?
No. In the described configuration, the PC uses NET communication through device 1 to transfer selected programs to the connected devices.
Can I download all four programs at once?
Select All in the download selection dialog, then confirm with OK. Check the transfer status for each intended target.
Does selecting device 1 download only its program?
No. Device 1 is selected as the NET communication route; the download dialog determines which device programs are sent.
What should I check if device 3 does not receive its program?
Verify NET mode, the selected master, device 3's availability in the download dialog, and the reported transfer completion status for device 3.
Final verification: confirm Easy Soft reports the intended program transfer complete for device 3.
