TON and TONR timers are available in three resolutions. The resolution is determined by the
timer number and is shown in Table 10-3. Each count of the current value is a multiple of the
time base. For example, a count of 50 on a 10-millisecond (ms) timer represents 500 ms.

The On-Delay Timer and Retentive On-Delay Timer
instructions time up to the maximum value when enabled. When
the current value (Txxx) is >= to the Preset Time (PT), the timer
TON
bit turns on.
The On-Delay timer is reset when disabled, while the Retentive
On-Delay timer stops timing when disabled. Both timers stop
timing when they reach the maximum value.
