ACX57xx

Netcontroller

Netcontroller II

Cause

The 182a error indicates that there is an issue with the controller IP Address settings. Some potential causes of this are:

  1. Duplicate IP Address, Improper submet mask, improper gateway, BACnet routing issues.
  2. It seems that it is logged when trying to change the IP address or use an enode id already used by another device.   This error can be caused by misconfigured IP address information including mask and gateway addressing.  Can also be due to improper BACnet routing.
  3. In one specific scenario the issue was the default router setting in the Controller. This was set to a device that was not a router to the network.

 
Confirming the configuration of all IP Devices on the network and getting a Wireshark capture can help to identify the potential cause.
 

 

 


 

Resolution

Removed the invalid IP address from the Default Router field and the 182a errors stopped appearing in the Controller Error Logs.
