7.2 OUT
Outline
OUT instruction drives coils of output relays (Y), auxiliary relays (M), state relays (S), timers (T) and counters (C).
1. Instruction format
→ For the number of instruction steps, refer to Section 7.15.
2. Applicable devices
S1: Special auxiliary relays (M) and 32-bit counters (C) cannot be indexed with index registers (V and Z).
S2: State relays (S) cannot be indexed with index registers (V and Z).
S3: "D.b" is available only in FX
3U and FX3UC PLCs. However, index modifiers (V and Z) are not available.
S4: This function is supported only in FX
3U/FX3UC PLCs.
Explanation of function and operation
1. When a bit device is used
A device described in OUT instruction turns ON or OFF according to the driven contact status.
Parallel OUT instructions can be used consecutively as many times as necessary.
In the program example shown below, OUT M100 and OUT M101 are parallel.
If two or more OUT instructions are executed for a same device number, however, the double output (double coil)
operation is resulted.
