Site Explorer Site Explorer. Currently trying to commission a Siemnes PLC and analogue card as above, can some please tell me if the wiring diagram is correct.
SIEMENS 6ES7 331-7HF01-0AB0
We have 5 2 wire mA signals, and the rest of the inputs are spare. This is universal card. You have to configure 2 wire or 4 wire along with voltage or current input in hardware configuration to read signals correctly. Check also if the measuring range module is pluged right. I’d see the connection diagram beforebut it didn’t show what to do with unused channels and I thought this might be the problemthe “manual” download does show how to wire these, so thanks for that.

I think I’ve discovered the issue we might be having, the unit was installed to the drawings we were issued, but 331-7hf01-0xb0 pretty certain it’s a 4-wire system on the other end of the cables and not a 2-wire as the drawings suggest! Anyhow, I’m off to switch the wiring around, and hope there’s been no damage to the card.
I’ll post later and let you know how I got on. When the transducer have thier power-supply not from the AI-Module through the wires for the measurement, it is a 4-wire-transducer. I’m stuck in between wiring the panel to the drawings not knowing what’s connected at the other 331-7hf0-0ab0 I have to say, Siemens don’t make it easy!
If for four wire you need to link all the negative sides of the signal to -ve, then why not do it within the square setting block you have to put in position to select the signal type. We only have five signals, so according to the manual I need to shot 6es unused inputs, but the channel 5 again why start at 0!!
New question published by tammu is split to a separate thread with the subject connect Th two wire transmitter with external power supply to 7KF02 AI module.

This contribution was helpful to 2 thankful Users Towome Markriko. Thanks everyone for your help. I’m afraid this is what comes when too many people are involved with a project.

Once again thanks for helping out. This was indeed the problem, the drawing was for 2 wire, in reality the system was 4 wire!! Making links for 14 terminals is both time consuming and costly! Surely it wouldn’t be too hard to enable monitoring on a per channel basis. Cheers, everyone for the help.
