Reset Value

When the module is configured for a linear counter, the counter is
reset to the value you enter in this word. This word allows you to
initialize the counter, when a reset condition occurs, to a specific
value other than zero. The range of this value is -32767 to +32767.

The example below illustrates reset values of -32,767 and +32,767.

Output Data File Word -
Range and Rate Modes

The Output Data File is only one word in size. Appendix D contains
worksheets for Range and Rate Mode operation.

O:e.0 Direct Outputs (Dynamic)

IMPORTANT

Resetting to a non zero value takes more time than
resetting to zero. It is possible to lose counts while a
non zero value is being loaded into the counter.
Refer to Timing Information in Appendix A.
