Metasys N2 and BACnet MS/TP are Serial based Protocol. The physical layer is RS-485 compatible, half duplex 9600 baud shielded twisted pair. The devices can directly communicate with each other only if they are on the same protocol. M4-CGM09090-0 The SlotServer ControlLogix Metasys N2 by JCI Communications Interface allows an Allen Bradley ControlLogix platform to pass data between a ControlLogix CPU and Johnson Controls Metasys N2 networks. 0. It is open to any manufacturer and based upon a sim-ple ASCII protocol widely used in the process control industry. JCI Metasys N2 is an extremely popular protocol used in Building Automation. Controllers running in N2 mode can be used to maintain or modernize sites with installed legacy Johnson Controls® controllers. Standard BACnet Protocol – Provides interoperability with other Building Automation System (BAS) products that use the widely accepted BACnet standard. The information in this manual is intended to provide you with comprehensive information on how to install and set up the frequency converter for communication over a Metasys network. All FEC and FAC controllers feature selectable N2 or BACnet® MS/TP communication protocol, this allows them to be used as functional replacements for legacy N2 controllers. We are a Johnson Controls Metasys Authorized Building Control Specialist ABCS FieldServer Protocol Driver Sheet Metasys® N2 by JCI FS-8700-19 Version: 1.05 / Rev. The communication rate is 9600 bps with 8 data bits, no parity, 1 start bit and 1 stop bit. Hence, a converter is needed which converts the data from BACnet MS/TP device to Metasys N2 and vice versa. Thus the device communicating with an MCH drive must be an N2 master. IntegrationTek offers excellent solutions to integrate your JCI Metasys N2 devices on other communication protocols like Modbus RTU , Modbus TCP/IP, SNMP, BACnet MSTP, BACnet IP, LonWorks and many others.

The N2 Bus follows the electrical characteristics of Electronics Industry Alliance (EIA) Standard RS-485. For easy networking, a removable screw terminal connector is provided. Many N2 compatible devices use their own version of the protocol and care must be taken to ensure that the device of interest is covered by the FieldServer implementation. This symbol means improper operation may results in serious personal injury or death. The N2 communications protocol is used by Johnson Controls and others to connect terminal unit controllers to supervisory controllers. The bit sequence is as follows: DATA It seems we can’t find what you’re looking for. Some information also says the N2Open protocoll is defined exactly for 3rd party vendors to be able to integrate to it, and that it is free. Communications Protocols The Metasys ... communications protocols, refer to the N2 Compatibility Options chapter of the Controller Tool Help (LIT-12011147). Metasys N2 is a master/slave control network. BACnet MS/TP is the default communications protocol for all new controllers. I have the protocol document from Johnson, but I'm under a time constraint and it looks a little beyond what I've been working on until now.
