Tip!
For decoding/coding the control signal, the function blocks L_DevSMControlDecoder and
L_DevSMControlEncoder are available in the function library from V2.0.
[2-3] Example: Decoding of the SMI_dwControl control signal into individual boolean control signals
2.5.3 "SMI_SafetyModuleInterface" system block for 9400 ServoPLC
For controllers of the "9400 ServoPLC" series the SMI_SafetyModuleInterface system block in the
control configuration of the »PLC Designer« provides the interface for the safety module.
Note:
This connection example only shows the control signals of the FB L_DevSMControlDecoder supported by SM301
V1.3.
