4 SAFETY FB SPECIFICATIONS
4.13 M+SF_OUTC_R
FB details
This FB is an output driver for a safety output. The safety output is controlled via M+SF_OUTC_R using a signal from the
standard application (i_bProcessControl) and a signal from the safety application (i_bS_SafeControl).
■ Optional conditions for process control (i_bProcessControl).
i_bStaticControl is able to set the option of an additional function start (i_bProcessControl OFF to ON) following the FB
activation or feedback of the safe signal.
• i_bStaticControl=OFF: An additional function start (i_bProcessControl OFF to ON) is required following FB activation or
feedback of the safe signal (i_bS_SafeControl). A static ON signal at i_bProcessControl does not set i_bS_OutControl to
ON.
• i_bStaticControl=ON: An additional function start (i_bProcessControl OFF to ON) is not required following FB activation or
feedback of the safe signal (i_bS_SafeControl). The static ON signal at i_bProcessControl sets i_bS_OutControl to ON if
the other conditions have been met.
Use safety data for connecting the variable whose data type is "Bit*" to input-output circuits.
Safe data (e.g. emergency stop demand) must not connect to i_bProcessControl. You are responsible for planning the behavior of the stop functions according
to the result of your risk analysis for the safety function.
