Chapter 4 Module Configuration, Output, and Input Data
Configuration Array
The configuration array, which consists of 118 words (46 words for the packaged
controller), lets you specify how the module’s counters will function. The default
value is all zeros with the exception of the following:
• NumberofCounters (see
page 75)
• CtrnMaxCount (see
page 78)
• CtrnMinCount (see
page 79)
• CtrnScalar (see
page 80)
• CtrnCyclicUpdateTime (see
page 81)
Word 0 contains general configuration bits. Word 1 contains the filter settings.
Words 2 through 5 refer to the physical outputs. Words 6 through 45 are counter
configuration words. Words 46 through 117 are range configuration words. More
detailed descriptions of the configuration words and bits follow the configuration
array below.
TIP
Normal counter configuration is done using programming software. In
that case, it is not necessary to know the bit location. However, some
systems let the control program change configuration. Refer to your
controller’s documentation for details.
IMPORTANT
When changing configuration values, verify that only valid configurations
are created for the module. For example, changing NumberofCounters
from its default of 1 to 0 requires that Ctr1MinCount and Ctr1MaxCount
also be set to 0, and so forth.
See the Configuration Error Codes table on page 117 if you encounter
configuration errors.
IMPORTANT
Certain values (noted below) cannot be changed while a counter or range
is enabled. Attempting to do so will cause a configuration error and the
entire configuration array will be rejected until the error is eliminated.

For the 1769-HSC/B module only. Bit 12 is Counter 0 reset disable; Bit 13, Counter 1 reset disable; Bit 14, Counter 2 reset disable; Bit 15, Counter 3 reset disable.
Counter reset function = 0: reset enable (default), 1: reset disable. See page 73 for details.
