RE: Modbus profiles examples - Daniel - 15.04.2025 Is the GND connected between devices?

Hi, The Modbus master device does not have a GND connection (see attachment ECP202EXP.PNG). RE: Modbus profiles examples - Daniel - 28.04.2025 Check all suggestions from this thread https://forum.logicmachine.net/showthread.php?tid=5946&pid=38562#pid38562 RE: Modbus profiles examples - admin - 28.04.2025 It's possible that INP-GND or PROBE-G can be used. Power down the unit and check resistance between INP-GND and PROBE-G. Most likely inputs are not isolated and resistance should be close to 0. Then check the resistance between RS485-A and INP-GND / RS485-B and INP-GND. Report the values that you get.
