Digital outputs

2.9.1 Two-channel safe outputs DOUT40 ... DOUT42 [X40]
Use
Use the two-channel safe outputs to:
– transmit safe status messages to external control devices.
– activate safety switching devices.
– when switched on permanently, they can be used as a source for test impulses.
Function
The safety module has three safe outputs DOUT40A/B, DOUT41A/B, DOUT42A/B. The outputs are
largely freely-configurable and can have various functions (safety function request, safe state reached,
errors, etc.) assigned to them. Thus, the operating status of the safety module or an individual safety
function can be transferred externally:
– to indicate the safety status to downstream drives,
– to request safety functions in downstream drives with safety module CAMC-G-S3,
– to indicate the safety status to an external safety controller or a function controller,
– to activate external safe actuators, e.g. a clamping unit, a valve vent, a door lock, or similar.
