REMARKS
100ms, 10ms and 100ms retentive timers can be changed using the built-in PLC function
parameter. (The default is a 100ms timer.)
Since the FR-C500 has 8 timers (T0 to T7), it can use only any one type of 100ms, 10ms and
100ms retentive timers.
When input X5 turns on, T2 coil turns on
and timer times 5s. (T2 is 100ms timer.)
