Problem with the S7-1200 with 4 channel analog output 4-20mA.

I having a problem with the S7-1200 with 4 channel analog output 4-20mA. I have config and test each channel with a multimeter and separately tested the output actuator with an mA simulator. But the error "Short circuit" appeared when I connect more than one actuator to the output module.

Also tried with barriers and results are the same, anyone has an idea.

Thanks,

Bon

Split from Problem with analog output on s7-1200.

 Hi,

since none of the s7-1200plcs have more than 2 built in analog outputs, and there is only one(standard) 1200-module with 4 outputs, i'm going to assume you're using the SM1232(6ES7232-4HD32-0XB0), but that's where my guesswork stops. 

You really should give an account of your equipment, and supply a drawing or picture of how you have wired it.
