The teach pendant shows the status of CMDENBL signal to be ON, however peripheral device can't read this signal!
Can the teach pendant indicate a signal is ON and not send any output to peripheral device when the Signal is UNSIMULATED (i.e. base emitter of transistor in output circuit not forward biased)!? If so how do i get it to send a signal to peripheral device!?
Is there a way to check if the transistors in output circuit is fried for DO signals on CRM2A port!? If so how do i go about checking!?
Thanks!
Noteworthy: port rack and slots have been verified, can send DI signals to controller, wiring triple checked
