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
functions, the output obtained at the I/O update is determined by the final results of the operation.
<Exmaple>
Output to the same output relay Y0 with OT, KP, SET and RST instructions.
When X0 to X2 are all on, Y0 is output as off at I/O update.
• If you need to output a result while processing is still in progress, use a partial I/O update instruction
(F143).
