Description
The fail-safe functions can be triggered via the fail-safe digital inputs FDI0 and FDI1 or via
PROFIsafe signals (see P9603 and 9803).
To use PROFIsafe for triggering the fail-safe functions the G120 GSD file must be installed
in the control system e.g. SIMATIC S7.
Input and output address, 6 byte each (input and otuput address are identical)
• Byte 0 (process data 0), Bit 0:
STO 0 = selected 1 not selected
• Byte 0 (process data 0), Bit 1:
SS1 0 = selected 1 not selected
• Byte 1 (process data 1), Bit 0:
SLS 0 = selected 1 not selected
