Question
ZEN Programmable Relays: Is it necessary to revise the ladder program in order to change the set values of timers and other set values?
Answer
No, the set values can be changed without changing the ladder program.
LCD-type CPU Units have a menu window for parameter settings.
The set values of timers, counters, weekly timers, and calendar timers can be changed through front-panel buttons without touching the ladder program.
