5.6.4 FEM_DO – Binary Input
The following OBs must call the function block FEM_DO:
Watchdog interrupt OB for cyclic operation (for example OB 32).
Area of Application
The block outputs 16 binary outputs to the AddFEM module.
Functional description
The input values DO_x are output to the assigned digital outputs of the AddFEM. If
the switch SIMUDOx = 1, the output channel is simulated, meaning that the value
DIx_SIM is output to the AddFEM module.
Mode of Operation
The block combines the digital outputs into a word and passes it to the
BLOCKCNO output structure for output by the FEM_AO block.
Error Handling
In case of a configuration error (for example DP address does not exist) the output
QPARF = 1 and all the channel fault outputs are set. In this case simulation is not
possible.
At channel faults the corresponding channel fault outputs are set = 1.
Start–up Characteristics
Do not exist.
Time Response
Does not exist.
Message Characteristics
The block does not have message characteristics.
Operator Control and Monitoring
The block does not have a faceplate.
