Issue
Need to connect MicroNet system to EcoStruxure Building Operation
Product Line
EcoStruxure Building Operation
Environment
- Automation server
- Enterprise Server
- MicroNet interface
Cause
MN-Mi interfaces are obsolete, need to find another way to connect to EcoStruxure Building Operation system.
Resolution
A MicroNet system uses one of two communications protocols, Native Communications Protocol (NCP) and Attached Resource Computer Network (ARCnet).
If the protocol being used is NCP, the MicroNet LAN can be connected directly to the AS-P/ES, A MicroNet interface can be added and configured.
If the protocol adopted is ARCnet, this does require the MN-Mi, to convert from RS 232 to ARCnet, the MN-Mi would be connected to the AS/ES using an RS232-485 converter.
If the MicroNet controllers are the older 100 series version, it may be possible to remove the auxiliary ARCnet cards, and reconfigure the MicroNet controllers and LAN to use NCP protocol.
If the MicroNet controllers are the 50 series type the cannot be re-confirmed as the communications components are on the main board.
PA-00246 provides more information on the possible connections.
