JFav, sorry for the delay in responding. I haven't used the TO instruction, and I've only used the built-in analog inputs on the PA. If you're using the built in analog outputs on the PA, you can simply use a MOV command to move a scaled output value to D1116 for CH0 or D1117 for CH1. If you need help with an expansion analog card, you may want to call Eaton customer support at 877 ETN CARE (877 386 2273). They have been helpful when I've called.
