Digital output Ready
The Ready output is designed as a potential-free contact. It indicates the operational readiness of
the module and is only set, if the module software works correctly (monitoring through internal
watchdog timer). The design as a potential-free contact makes it possible to easily link several
Ready outputs. This sum signal can be processed e.g. in the safety circuit.
