I’d see the 00ab0 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. Data Sheet and Wiring Manual chapter 5. Surely it wouldn’t be too hard to enable monitoring on a per channel basis.
This contribution was helpful to 2 thankful Users Towome Markriko. Currently trying to commission a Siemnes PLC and analogue card as above, can some please tell me if the wiring diagram is correct. When the transducer have thier power-supply not from the AI-Module through the wires for the measurement, it 0av0 a 4-wire-transducer.
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.

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. Once again thanks for helping out. I think I’ve discovered the issue we might be having, the unit was installed to the drawings we were issued, but I’m pretty certain it’s a 4-wire system on the other end of the cables and not a 2-wire as the drawings suggest!
You have to configure 2 wire or 4 wire along with voltage or current input in hardware configuration to read signals correctly. I have to say, Siemens don’t make it easy!

I’m stuck in between wiring the panel to the drawings not knowing what’s connected at the other end: We only have five signals, so according to the manual I need to shot out unused inputs, but the channel 5 again why start at 0!! Site Explorer Site Explorer.
Thanks everyone for your help. Hi new to Siemens so please be gentle.

Check also if the measuring range module is pluged right. This is universal card. This was indeed the problem, the drawing was for 2 wire, in reality the system was 6fs7331 wire!!

We have 5 2 wire mA signals, and 6e7331 rest of the inputs are spare. Making links for 14 terminals is both time consuming and costly! 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.
Hi, This is universal card. Cheers, everyone for the help. I’m afraid this is what comes when too many people are involved with a project. Product Support Services Forum mySupport. There is no bad feedback!
