2.3.1.2 I/O-Status information
The bit-coded wIOState status signal serves to transfer the status the safe inputs and the safe
output:
[2-2] Bit coding of the wIOState status signal
2.3.1.3 Control information
The bit coded wControl control signal serves to transfer information about requested or active
safety functions. The application in the controller must evaluate the control signal and carry out the
corresponding action.
• It is possible to request/activate several safety functions at the same time.
[2-3] Bit coding of the wControl control signal
Bit Name Meaning
0 SD-In1 Sensor input 1 in ON state.
1 SD-In2 Sensor input 1 in ON state.
5 AIS Restart is acknowledged via terminal (negative edge: 10).
6 AIE Error is acknowledged via terminal (negative edge: 10).
8 PS_AIS Restart is acknowledged via safety bus (positive edge: 01).
9 PS_AIE Error is acknowledged via safety bus (positive edge: 01).
Unlisted bits are reserved for future extensions!
Bit Name Meaning
0 SS1 active Safe stop 1 (SS1) is active.
2 ES active Enable switch (ES) function for motion functions in special operations is active.
3 OMS Operation mode selector (OMS) function for special operations is requested.
4 SSE active Emergency stop function (SSE) is active.
• Depending on the parameterisation of the emergency stop function, bit 1 (SS1
active) or bit 0 of the status signal SMI_wState (STO active) is set after the
function has ended.
5 OMS active Special operation is active.
Unlisted bits are reserved for future extensions!

Note!
The application in the controller must evaluate the control signal wControl and carry out
the corresponding action. The execution of the corresponding action (e.g. braking to
standstill) requires an appropriate application interconnection which must be provided
by the operator!
See the following subchapter "
Transferring the control information to the application ".
