Hello,

I have a problem with a ET200 module (6ES7 135-4FB01-0AB0), when I sent a value of 20736 to the PQW of the module, the output voltage stays at 0V, I have wired everything corrected. Strange enough when I put a substitute value in the HW-config for the channel (ex 5V) it will be sent out correctly when I put the cpu to stop. When I change to run the voltage drops again to 0V.

I'm working with TIA-portal, and I have the following code to sent a value to the output

L 20736

T QW 500

Is there anything I'm missing ?

Thanks,

Kevin

Hello,

do you check the value of QW500 at a watch table?

It looks like that you anywhere write the QW500 again, maybe wtih 0 or something, please check it with a watch table.

I hope this is helpful.

Hello,

Already checked this in the watch table the value is also 20736 there.

Best regards,

Hi Kevin,

Was the output address assigned right?

please check the same

I doesnt know this could help you, but you can write with PQW500 instead of QW.

i had counting module where i read the values with piw since i didnt get the values in iw long back.

i could not find the reason why...
