CODESYS MOVE

MOVE is an IEC operator that assigns the value of one variable to another variable of a corresponding type. In CODESYS it can be used in CFC, FBD, and LD editors, where EN/ENO functionality can control whether the assignment occurs. In structured text, ivar2 := MOVE(ivar1); is equivalent to ivar2 := ivar1;.

Study notes

The source and destination variables must be of corresponding types.
In CFC, FBD, and LD editors, EN/ENO functionality can control whether the assignment occurs.
In the CFC example, assignment occurs only when en_i is TRUE.
The structured text form ivar2 := MOVE(ivar1); corresponds to ivar2 := ivar1;.
