Hi Guys!
I'm having real difficuly connecting a Lem current transducer (AT 100 B420) to a ET200s Analog module (6ES7 134-4GD00-0AB0).
I've tested the analog module with a 4-20ma generator all ok. And I've wired my meter in series with Lem when not connected to the analog mdule and get 4ma. But when I connect the two together I get nothing?
I've tried wiring the Lem directly to the analog module and in a powered loop but get nothing either way (
Am I missing something, it's been a while since I've messed around with this stuff.
Thanks
Roger
