TELETERM M3E RTU Not Detected on ISAGRAF ACP – Communication Help Needed

[JOHN9]

Hi Community,

I'm working on setting up a Teleterm M3E RTU using the IsaGRAF Automation Collaborative Platform (ACP). I'm currently facing issues where the RTU is not being detected as a device in the IsaGRAF environment.

🔧 My setup:

• RTU Model: Teleterm M3E

• Communication: RS-485 via USB-to-RS485 adapter

• Platform: IsaGRAF ACP

• Objective: Upload/download program and monitor gas detection system

❗ Problem:

• The RTU is not recognized when I try to add a device in IsaGRAF ACP.

• No communication link seems to be established.

✅ What I've tried:

• Verified the correct COM port via Device Manager.

• Confirmed baud rate and serial settings.

• Used the same USB-RS485 adapter on another Modbus RTU (works fine).

• Checked cabling and termination.

🔎 What I need help with:

1. Correct steps to add and detect a Teleterm M3E RTU in IsaGRAF ACP.

2. Required drivers or plugins for device recognition.

3. Recommended serial/Modbus settings for reliable communication.

Any guidance or documentation links would be highly appreciated.

Thanks in advance!
