Question :
Where can I find the detailed description of safety machinery functions blocs listed below and available in the safety libset of Control-Expert ?

• Folder “ActuatorConnection” :
  • S_EDM
  • S_ENABLE_SWITCH
  • S_ESPE
  • S_GUARD_LOCKING
  • S_GUARD_MONITORING
  • S_MODE_SELECTOR

  • S_ANTIVALENT
  • S_EQUIVALENT
  • S_EMERGENCY_STOP
  • S_TWO_HAND_CONTROL_TYPE_II
  • S_TWO_HAND_CONTROL_TYPE_III

Answer :

Overall description is available in user documentation available in Control-Expert. However, further details (complete state machine and detailed transitions)  are available in the standard from PLCopen.org website and attached to this FAQ: “plcopen_safety_part_1_v1.0.pdf”.

Note: these function blocs are not following the further revisions of this specification from PLCopen (example: “PLCopen Safety Part 1 version 2.01”). They have been coded on the basis of version V1.0 of the PLCopen standard.
