Issue
A correct IP, Subnet Mask, and Default Gateway addresses are required for the MNB-1000 to communicate properly via BACnet/IP but what about BACnet Ethernet?
BACnet IP requires a valid IP address to be routed in a TCP/IP network. please read the example below in the resolution
BACnet Ethernet requires a valid six-byte MAC address assigned by the manufacturer and only operates within layer 2 of the OSI model. It is non-routable protocol
Example of Ethernet address: 00:00:AC:56:78:90
Product Line
TAC IA Series
Environment
I/A Series MNB 1000
Cause
BACnet IP is a requirement and needs information on configuring the settings to enable communications.
Resolution
MNB-1000 controllers must have a valid IP address, Subnet Mask address, and Default Gateway address for the communication ports to function properly if BACnet/IP is enabled. If 0.0.0.0 is used, the communications ports may be disabled and no longer communicate after the controller is reset. In the event that 0.0.0.0 was entered and the communications port is disabled, there is currently no field workaround or way to repair it. The controllers will have to be returned to the factory for repair. Never enter an invalid IP, Subnet Mask, and Default Gateway address for new installations. Review and update current installations. To connect to the MNB-1000 for the first time it will require an Ethernet connection. When you select the BACnet IP tab and enable IP the default IP address from the factory is a valid address of 10.1.10.2 with a subnet mask of 255.255.255.0. Default example:
- IP address 10.1.10.2
- Subnet mask 255.255.255.0
- Gateway 0.0.0.0 (If you do not have a default gateway IP address then enter 0.0.0.0 in the default gateway section)
