Error Codes
The gateway's error codes are listed in this section. Error codes returned from
the command list process are stored in the command list error memory region. A
word is allocated for each command in the memory area.
Use the error codes returned for each command in the list to determine the
success or failure of the command. If the command fails, use the error code to
determine the cause of failure.
Note: The gateway-specific error codes are returned from within the gateway and never from an
attached server device.
4.3.1 BACnet Client Protocol Error Codes
These are error codes that are part of the BACnet protocol or are extended
codes unique to this gateway. The standard BACnet error codes can be found in
the BACnet Protocol Standard, section 21.
