MANOJ.N Posts: 81 Rating: (2)	Hello, From that AO, i am generating refrence value to my load. But it is not receving any value from PLC AO card. Hence i am cheking values on AO module. On module also, it failed to display any reference as per my forced values. Regards, manoj

Ste39 Posts: 4620 Rating: (710)	Hi again, If you want to do an empirical test, remove the load 4-20ma, if you have a resistance of about 1300 ohm 1/4 watt you can put it in parallel to the analog output and see if it comes out a voltage (0-10V) corresponding to the value of your that you put to the exit. Do not touch the hardware configuration. Channel 0 ----> 3 + 6 -

MANOJ.N Posts: 81 Rating: (2)	Hello, I dont have this, to test AO module. No one can test this modulein their offices/labs??? I think, there is problem in module itself. There are 3 modules in my system, but any single module is not sourcing mA value. regards, manoj
