Hello; Error code Hex 80C8 in this case appears to be related to the Modbus RTU MB_Master instruction from Sep 7 (v1x). Status 80C8 indicates a Modbus slave timeout. https://support.industry.siemens.com/cs/ww/en/view/109773506/113896548491 That could be caused by many issues. The first suggestion is to start by identifying which slave is faulty, see if any of the Modbus slaves shows error LEDs or codes in the field. Hope this helps, Daniel Chartier |
