13.4.2 I/O status information
The bit-coded wIOState status signal serves to transfer the status the safe inputs and the safe
output:
[13-2] Bit coding of the wIOState status signal
13.4.3 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.
[13-3] Bit coding of the wControl control signal
Bit Name Meaning
0 SD-In1 Sensor input 1 in ON state.
1 SD-In2 Sensor input 2 in ON state.
5 AIS Restart acknowledgement via terminal effected (negative edge: 10).
6 AIE Error acknowledgement via terminal effected (negative edge: 10).
8 PS_AIS Restart acknowledgement via safety bus effected (positive edge: 01)
9 PS_AIE Error acknowledgement via safety bus effected (positive edge: 01)
Bits not listed are reserved for future extensions!
Bit Name Meaning
0 SS1 active Safe stop 1 (SS1) is active.
2 ES active Enable switch (ES) for motion functions in special operations is active.
3 OMS Operation mode selector (OMS) for special operations is requested.
4 SSE active Emergency stop function (SSE) is active.
• At the end of the function, bit 1 (SS1 active) or bit 0 of the status signal
SMI_wState (STO active) is set according to the emergency stop function
parameterised.
5 OMS active Special operation is active.
Bits not listed are reserved for future extensions!

Note!
The application in the controller has to evaluate the wControl control signal and execute
the corresponding action. This action (e.g.braking to a standstill) has to be implemented
by a corresponding application interconnection, which has to be carried out by an
application engineer!
See the following subchapter "
Transferring the control information to the application ".
