Issue
Update OS, changing a controller, BACnet to Infinet or Infinet to BACnet
Can b3 controllers be converted to i2 controllers?
Can i2 controllers be converted to b3 controllers?
Converting between bCX4040 and bCX9640
Product Line
Andover Continuum, EcoStruxure Building Operation
Environment
- i2 b3 Controllers - See Compatibility Matrix
- bCX Controllers - Continuum 1.7 onwards
Cause
Only a limited number of controllers can be converted, BACnet to/from Infinet, using Update OS.
Resolution
The following controllers can be converted between Infinet and BACnet, using the appropriate firmware files:
- bCX (bCX4040 to/from bCX9640) (options like Xdrivers, node count, IO modules and expansion IO modules are not effected)
- i28xx-V - b38xx-V (i2865-V to/from b3865-V, i2866-V to/from b3866-V, i2885-V to/from b3885-V)
- Please see link for swapping the firmware of non -V model i2/b3
Attempting to flash (Update OS) any other controllers BACnet to/from Infinity is not recommended.
In nearly every instance, the result will be a non-functioning controller.
UPDATE:
A procedure is now available to convert the non -V i2s to b3s in the field
(Note: In the bCX controllers, the ACCNetID will revert back to the default of "1", you may need to change this in the Controllers configuration webpage back to what it should be. See Will IP settings persist when flashing a bCX4040 (BACnet) to a bCX9640 (Infinet)? for details.)
Please refer to Exchange for specific firmware:
The following can be used as a general rule to determine which OS is currently running in the controller. bCX only. (b3 & i2 CPU is green)
- CPU LED is Green = BACnet OS
- CPU LED is Yellow = Infinet OS
