Configuration Diagnostics
When a configuration is sent, the module performs a diagnostic check to see that
the configuration is valid. This results in either a valid ModConfig bit or module
configuration error. See the
Configuration Error Codes table on page 117
configuration error codes.
Post Configuration Diagnostics
If the ModConfig bit in the input array is set, then the module has accepted the
configuration. Now, on every scan, each channel status flag in the input array is
examined. The output array is checked on each scan for compatibility with the
configuration array.
Non-critical versus
Critical Module Errors
The 1769-HSC module has non-critical and critical errors.
Non-critical Errors
Non-critical module errors are typically recoverable. Non-critical error
conditions are indicated by the extended error code. See the
for more information.
Critical Errors
Critical module errors are conditions that prevent normal or recoverable
operation of the system. When these types of errors occur, the system typically
leaves the Run or Program mode and enters the fault mode of operation until the
error can be dealt with. Critical module errors are indicated in the
Common Hardware Error Codes table on page 116
TIP
The OK status indicator will be in a flashing red state for all of the error
codes in the
