Changing Analog Output While CPU is Stopped
Precautions for Programming ANST Macro
When using the FC4A-K2C1 analog output module, the analog output value can be changed while the CPU module is
stopped. To change the analog output value, store a required output value to the memory addresses allocated to the analog
output data.
Example: Memory Allocation of Ladder Refresh Type Analog Output Module FC4A-K2C1

Ladder Diagram
Note: The above ladder diagram is only an example and should be modified as required.
When using the ANST macro, do not make a branch from the ladder line of the ANST macro.
Delete the branch from the ANST macro, and start another line by inserting a LOD instruction.
