4.2.2 When Output is Repeated with an OT, KP, SET, or RST Instruction
Condition of internal and output relays during operation
When instructions are repeatedly used which output to internal and output relays such
as transfer instructions and OT, KP, SET and RST instructions, the contents are
rewritten at each step during operation.
Example: Processing when SET, RST and OT instructions are used (X0 to
X2 are all on).
The output is determined by the final operation results.
If the same output is used by several instructions such as the OT, KP, SET, RST, or data
transfer instructions, the output obtained at the I/O update is determined by the results
of the operation at the greatest program address.
Example: Output to the same output relay Y10 with OT, SET and RST
instructions.
When X0 to X2 are all on, Y10 is output as off at I/O update
according to the result of trigger X2.
If you need to output a result while processing is still in progress, use a partial I/O update
instruction F143 (IORF).
