If the module has no configuration, it refuses connection requests from the ControlLogix
processor and returns an error.
The Debug Log
The firmware on the module maintains a log of informational and diagnostic messages
that can be useful in determining the cause of configuration and I/O bus problems.
To view the log, run the program LogMon from the Start Menu.
Diagnostic Counters
Refer to page 18 for details about monitor mode diagnostic counters.
Refer to page 31 for details about master mode diagnostic counters.
Slot Status Bits
The QTS-CLX-APACS maintains an array of bits that indicate the status of the APACS
modules.
Use the slot status bits to determine when you can access data from a module. Some
APACS modules take several seconds to go online.
In master mode, the bit is 0 if the module has good communication status and is 1 if the
associated module is in error or is not responding.
In monitor mode, the bits do not update and are always 0. Aliases to the bits are provided
by the configuration tool for compatibility with master mode.
Aliases for these bits have names like
APACS_SlotStatus_R01S04
