4.5 Timer [T]
Timers add and count clock pulses of 1 ms, 10 ms, 100 ms, etc. inside the PLC. When the counted value
reaches a specified set value, the output contact of the timer turns on.
A set value can be directly specified by a constant (K) in the program memory, or indirectly specified by the
contents of a data register (D).
4.5.1 Numbers of timers
The table below shows timer (T) numbers. (The numbers are assigned in decimal.)
1. FX3U/FX3UC PLC
2. FX
3G PLCs
Timer numbers not used for timers can be used as data registers for storing numeric values.
*1. In FX
3U/FX3UC PLCs, retentive type timers are backed up by the battery.
*2. In FX
3G PLCs, retentive type timers are backed up by the EEPROM memory.
