A Timer Reset sets the timer’s accumulator to 0. After a timer expires, it must be reset before 

starting it again.

A Timer Restart sets the timer’s accumulator to 0 and starts the timer (combines the 

functions of Reset and Start). 

A Timer Stop causes the accumulator to hold its current value. 

Counters are 32-bit values that have a range of 0 to 99,999,999. Counters also have Name, 

Preset, and Description fields available for access in the Data Items Editor. The main 

characteristics of Counter data items are:

–

Counters can count upward (increment) and downward (decrement).

–

Specify a Preset for each Counter in the Data Item Editor. The preset is the Counter’s 

ending value.

Ways in which project components can interact with a Counter include:

–

A Control block can increment, decrement, or clear a Counter.

–

A Compare block can compare the Counter’s current value with another variable or 

constant.

–

A Move block can replace the current value with a new value or read the current value.

In Control blocks, the following actions on a Counter are possible:

–

Increment

–

Decrement

–

Reset 

A Control block can increment or decrement a Counter each scan. Counting is not 

transition-based, as in other types of controllers.
