Module Configuration, Output, and Input Data

Chapter 4

Counter Reset (CtrReset)

Bits 12…15 in the configuration array correspond to the counter reset selection
bits for counters 0…3, respectively. The Counter Reset Enable in the Add-On
profile lets you select which counter to be enabled or disabled. An enabled
checkbox indicates a zero (0) in the respective counter reset selection bits in
RSLogix 5000 software.

If you do not want a counter to reset by default, you must uncheck the box in the
Add-On profile for the respective counter reset selection bit. A ‘1’ will display in
the configuration array to denote that this bit is disabled from resetting a count.
The individual counter reset functionality for the 1769-HSC/B module is
reverse logic, with a 0 = enabled and a 1 = disabled, for RSLogix 5000 software.

Figure 19 - Configuration for Individual Counter Reset Enable

As shown in Figure 19, the Counter Reset Enable box defaults with a check mark
to indicate the respective counter is enabled in the Add-On Profile. Therefore,
the individual counter reset functionality is enabled for the selected counter of
the 1769-HSC/B module. The corresponding controller tag in RSLogix 5000
software displays a zero (0) for enabled.

IMPORTANT

The individual counter reset functionality applies only to the 1769-HSC/B
module used with CompactLogix controllers and the CMX 5370 L2
packaged controller embedded HSC. You cannot use the individual
counter reset functionality with MicroLogix controllers.

Counter 0 in this
example equates
to individual
counter reset
selection bit 12.
