I want to use the "Output Data Echo" feature in ControlLogix Output Modules (1756-OB32 and 1756-OF8). Their documentation 1756-UM009 says, we csn use the following tag for Channel data echo feature.
"Ch0DataEcho (INT) (valid for all outputs)
The value the channel is currently outputting in counts where -32,768 counts is the minimum producible output signal and 32, 767 counts is the maximum producible." (1756-um009)
The problem is when I define an anaolg output or digital output module in RSLogix5000, I can't see any Ch0DataEcho tag in Controller tag list.
If anyone knows how to use this feature to confirm the output value, please help.
