Display
Display in IOP or STARTER:
In IOP / STARTER, parameter r0002 is used as "Drive operating display".
Enable and inhibit signals as well as operating states are displayed here, e.g.:
● r0002 = [44] Switching on inhibited – connect 24 V to terminal STO (hardware)
– STO active in one or both STO channels
● r0002 = [31] Ready for switching on – set "ON/OFF1" = "1/0" (p0840)
– Drive is ready to switch on, the start signal is still missing
– An STO is not available at any STO input-> STO_A and STO_B have a 1 signal
Display at the F-PLC:
Refer to the corresponding documentation for the display of the operating state at the F-PLC.

A.3 Application examples for functional safety (STO / SS1-t)
Activate the STO circuit, bring both activation switches S41 towards the front.
No settings are required in the CU230-2 for STO.
The F-PLC (e.g. a SIMATIC PLC) must be programmed in accordance with the
safety functions required. This safety function is directly implemented in this F-
program. The feedback inputs must be integrated for diagnostic purposes.
