(5) Appendix 5 (2) [Diagram App.20 A program example] 1) Operation of the program before correction
When 32768 seconds (around 9. 1 hours) elapses after the CPU module became RUN status, SD412 value will be –32768. In the following program (before correction), since the processing is repeated in the relevant program until the SD412 value will be 10 or more again (around 9. 1 hours), other sequence operations cannot be performed. Note when this occurs, the CPU module will not be STOP status even the RUN/STOP switch is set from RUN to STOP.
2) Corrections
The method for starting with the previous control system has been corrected in the example of a program when mounting a network module to the base unit as shown below.
(Before correction)
(After correction)
User program
Permits system switching after System B's network unit has started properly.
Executes the system switching instruction after System B's network unit has started properly. Jumps to the END instruction during system switching command execution.
Enables communication with GX Developers or others.
Resets the watchdog timer.
Jumps to P0 until SD412=10 (10 seconds).
Program which waits 10 seconds while System B's network module is starting
Makes the subroutine program (P100) execute when the previous control system is the system B. Jumps the processing to the END instruction by executing the system switching instruction.
Ends the main routine program.
Stores the value of SD412 at subroutine program execution to D400.
Enables system switching when the network module in the B system starts normally.
Executes the system switching instruction when the network module in the B system starts normally. Jumps the processing to P101 with the system switching instruction.
Enables communications with GX Developer or others. Calculates the subroutine program executing time.
Resets the watchdog timer.
Continues the jumps to P100 until the SD401 value becomes 10 (10 seconds).
Ends the subroutine program.
