22 Compact I/O High-speed Counter Module
Publication 1769-IN030B-EN-P - October 2010
Module Powerup
At module powerup, a series of internal diagnostic tests are
performed. These diagnostic tests must be successfully completed or
the module OK status indicator remains off or red, and a module
error is reported to the controller.
Diagnostic Indicators
Default Configuration
When the module is powered up for the first time, it uses the following default configuration
values. All counters are disabled and all outputs are off. The module’ s Default Safe State
configuration is all zero’s, resulting in the following:
• Program State = UDSS (user-defined safe state)
• Program Value = OFF
• ProgramStateRun = No
• Fault State = UDSS (user-defined safe state)
• Fault Value = OFF
• FaultStateRun = No
• PFE (Program to Fault Enable) = leave program value applied.
Refer to the Compact I/O High-speed Counter User Manual, publication 1769-UM006
, and
use your programming software to change the configuration.
