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.
