Connecting digital outputs
Installation
Like the previous wiring example, the above sample circuit shows a single-pole M digital
output without monitoring.
5.9.2 Dual-channel switching digital output, monitored
The dual-channel wiring of an external power contactor can also be implemented with
monitoring. The prerequisite for this solution is a switching element with monitored
forced contacts and test contact (NC contact). The monitoring contact is fed via pulse
output P1 and read via any input. The software of the EMU function block (Emergency
Monitoring Unit) must be configured correctly for this solution to function properly.
