For easy networking, a removable screw terminal connector is provided. 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. METASYS N2 PROTOCOL 1-1 Introduction: Metasys N2 is a Johnson Controls system communications link. June 2007. 2.1 Metasys N2 Communications MC3000 drives running N2 protocol act as N2 devices on a Metasys® Network and function as slaves only. The communication rate is 9600 bps with 8 data bits, no parity, 1 start bit and 1 stop bit. The Metasys N2 network supports communications with a diverse range of devices. It seems we can’t find what you’re looking for. The N2 communications protocol is used by Johnson Controls and others to connect terminal unit controllers to supervisory controllers. June 30, 2011 - ProSoft Technology will distribute QuickServer Protocol Gateways from FieldServer Technologies for BACnet, LonWorks and JCI Metasys N2 networks The QuickServer gateways enable communication between these common building automation protocols and several of the more pervasive serial and Ethernet protocols, including EtherNet/IP and Modbus TCP/IP. 0 % off. 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. In MS/TP mode, these equipment controllers are BACnet® network compliant devices. M4-CGM09090-0 The communication rate is 9600 bps with 8 data bits, no parity, 1 start bit and 1 stop bit. Metasys N2 - general info The N2 communications protocol is used by Johnson Controls and others to connect terminal unit controllers to supervisory controllers. Thus the device communicating with an MCH drive must be an N2 master. 3 EA Airflow 0-360l/s Present extract airflow. Each communication link can handle 32 devices with address range from 1 to 255. 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. use with the Johnson Controls Metasys N2 protocol. Hence, a converter is needed which converts the data from BACnet MS/TP device to Metasys N2 and vice versa. It is on the physical layer RS-485 set of data communications standards and supports 9600 baud, 8 data bits, and no parity and in half-duplex mode only. Metasys® Controllers. Switchable communications protocols between BACnet MS/TP and N2 protocols. Johnson controls has a copy of their communication protocol and message structures that can access the Metasys Network through the ARCNET information to write software which can access Metasys data What language would one use to write programs to communicate with Johnson N30 controlers The closest Program I have written for a control device was for a Radio Shack Basic stamp … 2 www.swegon.com Analog Input (AI).32 bit IEEE-standard floats (RO). BACnet MS/TP is the default communications protocol for all new controllers.
