5.2.5 Timer processing
The XGB series use up count timer. There are 5 timer instructions such as on-delay (TON), off-delay (TOFF),
integral (TMR), monostable (TMON), and re-triggerable (TRTG) timer.
The measuring range of 100msec timer is 0.1 ~ 6553.5 seconds, 10msec timer is 0.01 ~ 655.35 seconds, and
that of 1msec timer is 0.001 ~ 65.53 seconds. Please refer to the ‘XG5000 User manual’ for details.
1. On delay timer
The current value of timer starts to increase from 0 when the input condition of TON instruction
turns on. When the current value reaches the preset value (Current value=Preset value), the
timer output relay (Txxxx) turns on. When the timer input condition is turned off, the current
value becomes 0 and the timer output relay is turned off.
