CAUTION

A sequence program cannot be written with its stepsthe sequence program does not run. (The program range is initialized.)

Do not read the built-in PLC function parameters anwithout writing them to the inverter once using GX inverter does not have normal data, always write theparameters and sequence program once.

Since the built-in PLC function parameters and sewritten to the flash ROM, there are restrictions on the n(Approximately 100,000 times)

until a sequence program is executed.The built-in PLC function processings are roughly classified intotypes.(1) Initial processing

Pre-processing for executing sequence operation. This proonly once when power is switched on or a reset is performed(a) The inputs/outputs are reset and initialized.(b) The data memories are initialized (the bit devices are tur

devices are cleared to 0).(c) Self-diagnostic checks are made on the built-in PLC

setting, operation circuit, etc.

(2) Sequence program operation processingThe sequence program written to the built-in PLC function is eto an END instruction.

(3) END processing

Post-processing for terminating one sequence program operareturn the sequence program execution to step 0.(a) Self-diagnostic checks are performed.(b) The present values of the timers are updated and their

on/off, and the present values of the counters are updateare turned on.

REMARKS

The built-in PLC function parameters can be confirmed from to the GX Developer Operating Manual.)

This section explains the operation processings of the built-in Poperating status.(1) Operation processing in RUN status

A RUN status indicates that a sequence program is repeating of step 0 to END (FEND) instruction while the SQ signal is ONWhen entering the RUN status, the function outputs the output saccording to the "STOP to RUN-time output mode setting" (refe

(2) Operation processing in STOP statusA STOP status indicates that a sequence program is stoppinthe SQ signal is OFF or after remote STOP is commanded. (When entering the STOP status, the function saves the outpuall outputs. The contents of the data memories other than maintained.
