TIMERS Sub-Menu
The TIMER sub-menu is used to configure the maximum time or count a timer will increment
to before setting it’s corresponding TD (Timer Done) input flag. The configured value
represents the time as a number of 100ms intervals. For example, a value of 0100 will result in
a counter triggering after 100 increments or a timer triggering after 10 seconds. Each timer can
be configured to be the type TON, TOF or RTON.
There are 32 independent timers available.
Timer Types
TON:
On Timer. TE (Time Enable) Flag is active when the rung for the timer rung output is
“energised”. Timer TT (Timer Timing) flag is active when counter is timing. When timer
value is reached, the TD (Timer Done) flag is active, and the TT is inactive. The timer count is
automatically reset at any time the rung is “de-energised”.
TOF:
Off Timer. Same as TON, but timer is not counting unless rung is “de-energised”. Timer is
auto reset when rung is energised.
RTON:
Retentive On Timer. Same as TON, but timer does not auto reset when the rung is de-
energised. In order to manually reset the timer the RT output must be operated.
STATE:
The current value of the timer, and any set timer flags.
