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

0SS1 active Safe stop 1 (SS1)

is active.

2ES active Enable switch (ES)

function for motion functions in special operations is active.

3OMS Operation mode selector (OMS)

function for special operations is requested.

4SSE 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".
