Several bits in the bit mask can be configured on a safety function, also. This safety
function is activated, as soon as one of the bits, which were configured for this case, is
set.
At operation of a SAF-module at a double axis the control word "S_ControlWord0" is
available at each axis.
The bit-assignment of the control word is shown in an example for the safety functions
STO/SS1/SS2/SOS and SLS in the following table for Axis 1. The assignment of the
control word is fixed via the configuration in ProSafePara. An assignment change always
must be adjusted in the profile of the FSoE-master.
With the setting of the configured bits in "S_ControlWord0", the FSoE-master can activate
the safe function. In the example, "STO" (Bit 1) and "SLS" (Bit 8) are activated at the same
time. ("S_ControlWord0" = 0x0102).

functions "STO" and "SLS" (dependent on the parameterized ProSafePara-
configuration).

WARNING!
The assignment of the control word must be adapted to the configuration of the
communication master (e.g. Safety PLC) before commissioning. Deviations will
cause failures, which can lead to serious consequences or even to death.
A detailed description in order to configure the control word S_ControlWord0 is described
in the manual „Parameterization Tool ProSafePara.
12.4 Control word "S_ControlWord1":
Parameter switchover and acknowledge of activated safety function
A general requirement is the switchover of parameterized data sets of a safety function;
at the same time another data set of this safety function is active (selected). The
switchover of data sets of a safety function can be made over FSoE only.
This functionality is, for example, used at the safe function SLS, in order to switch over a
momentarily monitored speed 1 without delay to another monitored speed 2, whereat the
safety function is not deactivated. The switchover is immediately effective.
