Operation Error
(1) There is no operation error in the ZONE(P) or DZONE(P) instruction.
Program Example
(1) The following program performs zone control by applying negative and positive bias values of
set at D0 and stores the result of control at D1 when X0 is turned ON.
[Ladder Mode]
[Operation]
• The value (D0) + (-100) is stored at D1 if D0
Example
D0 -200 D1 -300
• The value 0 is stored at D1 if D0
• The value of (D0) + 100 is stored at D1 if 0
Example D0 700 D1 800
