The elements for the single timer that is configured by default include EN, TT, DN, BASE, PRE, and ACC.
A timer is used to control the timing of a logic event.
For a MicroLogix 1100, the Preset element can be set from 0 to 32767.
Each timer requires three words of memory.
The first word holds the values of the binary elements
The second word is used for the preset, and the third word is used for the accumulator.
