Hello,

I am trying to test 6ES7134-4GB52-0AB0 module with this signal current generator: 

https://www.rcscomponents.kiev.ua/datasheets/sg-002_signalgenerator_english-manual.pdf

How should I wire the device?

Thank you in advance

 Hello rluqueb：

1.From you signal generator you supply，the signal generator can selection  2wire_4-20ma or 3\4wire 20 ma connection mode。

2.from you siemens et200s module 2AI 2wire hs  ，it is support 2wire 4-20ma sensor。

so，Let's connect as，the signal generator  terminal  AI+  connect to ET200S module terminal   1 (M0+) ,the signal generator  terminal  AI0  connect to module  terminal  2 (M0-) 。

note：1、see the picture et200s 2AI 2wire module Wiring diagram

I have connected the signal generator as follows:

Signal Generator 24V: To L+ in PM-E 6ES7138-4CA01-0AA0

Signal Generator GND: To M in PM-E 6ES7138-4CA01-0AA0

Signal Generator AI+: To Mo+ Terminal 1 in 134-4GB52-0AB0

Signal Generator AIo: To Mo- Terminal 2 in 134-4GB52-0AB0

But it doesn't seem to work, Bytes IB304 - IB305 don't change their values

I was reading the wrong addresses. They are PIW304

It works. Thank you

Ok ，No welcome ，see you late
