3.8.2 Case study 2: "Signalling"
Switching condition

• Safe signalling is carried out (SD-Out1 in ON state) if
• the power supply for the motor is safely interrupted (STO active)
• AND NO error is active (Error active).
[3-2] Logic operation for case study "Signalling"
Required parameter setting for SD-Out1
1. Set the following switching condition to "Positive logic":
• STO is active
2. Set the following switching condition to "Negative logic":
• Fault active
3. Set all other switching conditions to "Not evaluated".
4. Set logic function to "AND".
5. If a safety bus has been parameterised:
• The "SD-Out1" bit of the safety control is considered in the ANDing.
• Hide the "SD-Out1" bit via the "S bus: Filter control data" parameter to suppress this access.
