6.3.4 Online switching points
WARNING
NOT a substitute for safety devices and protective equipment
The online switching signals S1 to S6 are NOT a substitute for safety devices and
protective equipment.
Use safety devices and protective equipment.
Note:
The switching signals S1 to S6 do not meet the requirements for a safety switch. It is the
responsibility of the owner of the complete system, such as a press, to equip the system with
the required safety devices and protective equipment.
Note:
Outputs S1 and S2 are permanently assigned to specific PLC outputs. The assignment for
outputs S3 to S6 can be custom-set (see section 6.1.2 “PLC outputs” on page 46).
The six switching signals S1 to S6 at the PLC I/O interface and/or Fieldbus interface can be used for
signalling in real time if a limit has been exceeded. In the "Setup realtime switchpoints" menu (M12), you
can assign the six signals to the active measurement channels X or Y and set the limit threshold. You can
also select for each I/O signal whether it is active high or active low.
The limit thresholds for the X measurement channel can refer to the absolute measurement signal or to
the relative zero point (Measurement mode reference: Y trigger). The DIGIFORCE
®
9311 only activates
the switching signals in "Measurement mode" and "Test operation".
