  • Page 86: Chapter 10 Constant Scan

    CONSTANT SCAN Since the processing time differs as per the execution/non-execution of command used in the program, the scan timer changes with every scan. By setting the constant scan, because a program can be repeatedly executed while keeping scan time at a specified amount of time, even when the execution time of the program changes, the I/O refresh interval can be constant.

"WDT setting time" > "Constant scan setting time" > "Maximum scan time of the program" When the maximum scan time of the program is longer than the setting time of the constant scan, it results in error. The constant scan time is ignored and it is executed with the scan time of the program.

    Appendix 5 Substitute Functions File registers To use a file register of the FX3 PLC, use functions of the FX5 PLC. A file register is a device that sets an initial value to a data register that has the same device number. The values of the file registers set in the built-in memory or memory cassette is transferred collectively to the data registers when the power of the FX3 PLC is OFFON or the PLC is STOPRUN.
