9.4 Change set value of timer (T) and counter (C)
• From the HPP, change set values of timers (T) and counters (C) existing in programs in the PLC.
• While the PLC is in the RUN status, set values can be changed if the program memory is
the RAM. While the PLC is in the STOP status, set values can be changed if the program
memory is the RAM or the EEPROM (with the write-protect switch set to OFF).
• Set values can be changed in two methods: the method to change over the device monitor
to the test mode and the method to change over the list program monitor to the test mode.
If the set value is changed by changing over the device monitor to the test mode for the CJ
instruction which uses two or more timers (T) or counters (C) having same No. in the step
ladder program, the timer (T) or the counter (C) nearest the step No. 0 in the program is
automatically regarded as the target. When changing the set value of a timer (T) or counter
(C) having same No., select a desired timer (T) or counter (C) in the list program monitor,
then change its set value.
