4.3 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.
