 NET Controller

Appendix 6 / Discrete Isolated Outputs 
The discrete isolated outputs allow the MICRO 4000 NET system status to be remotely monitored 
by a customer's PLC. There are five status outputs: IN LIMIT, OUT LIMIT, SERVO-CENTER 
LIMIT, AUTO MODE, and NO FAULT. All outputs are opto-isolated. 
Warning:  It is the responsibility of the customer to insure machine safety. Changing the 
mode of operation from any source - front-panel switchpad, fieldbus, or Discrete Isolated 
Inputs - can cause machine motion.
