hi all,

I am using ET200 SP- CPU 1510/1PN PLC with one 4 wire AI module & one 2 wire AI module(6es7134-6hd00-0ba1). $ wir emodule does not show any fault but 2 wire module diagnostic LED shows red Blink.

Please give me solution.

Hi,

can you read the diagnostic buffer from your CPU or can you go online and look in the Device View to your module to make an online diagnostic?

hi,

what kind of transducer do you have?

Does it have a external power supply?

If yes, only a 4 wire AI module is the right for your purposes. 

hope this helps,

regards,

We configured it as voltage type. But what is the meaning of "parameter assignment error". Which parameter i have to assign...?
