Counter Display
The Counter Display, Figure 48, contains a list of the counters in the device. This
display is accessed by selecting a Ladder Logic object (MOD_LL_DEV) and then
selecting MOD300 TLL Counter from the context menu.
TLL counters can count by increments of one. Instructions in the programs can
cause them to count up or down, reset, or go to their configured preset values.
Counters can count as high as 2,147,483,647. Counters are required by a number of
instructions such as file instructions and sequencer instructions. Down counting
starts at the Preset and is finished when the count Value = 0. Up counting starts at
the count Value = 0 and is finished when equal to the Preset.
