Appendix B Task Codes Specifications
(Example) When “H05” (change time base and set value number 2) is set as the modification code, set “0” for the I/O code
(f1) and the I/O number (f2) of the set value number1, which is not to be modified.

H00: Counter
H01: 0.01 second timer
H02: 0.1 second timer
H03: 1 second timer
The counter can be specified when the timer counter number is H0000 to H01FF (0 to 511).
The 0.01 second timer can be specified when the timer counter number is H0000 to H003F (0 to 63).
The 0.1 and 1 second timers can be specified when the timer counter number is H0000 to H00FF (0 to 255).

Description
Modifies the timer counter set value within the ladder program. While the CPU is running, the set values are modified
without stopping the scan when the normal scan END command is executed.
Note : When an address other than H0000 is designated, the settings will be modified if an error with the return code H04
(address error) or H0F (program not logical) occurs or if the timer is written to the designated address in the user
program area, so take caution.
