Good day
I am wondering if the problem i have is the hard wiring or the modbus comms. I have a couple of temperature sensors pt100 reporting to a temperature polling station. Then the polling station reports to a siemens s7 400 plc via RS485. The problem is 6 out of the 18 temperature sensors are not showing on the scada hmi. could it be an electrical wiring problem on the instrumentation or a modbus coms issue
