Chapter - 1. BMS Communication Protocols
The MCS-Magnum supports as standard: BACnet IP, Modbus RTU, and Modbus TCP/IP protocols.
Using the MCS-BMS-GATEWAY, the MCS-Magnum can also support Johnson N2, LonTalk and Bacnet MS/TP.
Supported baud rates for Modbus RTU and Johnson N2 are 4800bps, 9600bps, 19200bps, 38400bps, and
57600bps.

1.9. Network inputs to MCS-MAGNUM
The MCS-Magnum can receive changes from the network to enable or disable the Network Run/Stop, Network Target
Reset (adjustments to the Cooling Target, Setpoint #1, based on Setpoint #21), Network Demand FLA, and Network
Demand Steps.
The MCS-Magnum must be set up to accept these inputs. The conguration le must contain a Network Run/Stop,
Network Target, Network Demand FLA, and Network Demand Steps sensors.
Magnum BACnet ID BACnet Name Modbus N2
Network Run/Stop AV:246 Net_R/S 40201 BO:247
Network Target/Reset AV:247 Net_Tar/Res 40202 AO:248
Network Demand/FLA AV:248 Net_Demad_FLA 40204 AO:249
Network Demand/Steps AV:249 Net_Demad_Steps 40205 AO:250
Note the following Information panel has a Network Run/Stop, and /or Network Target Reset sensors inputs indicated.
This is an example of how MCS-Cong must be setup in the General Information and Evaporator Information panels.
The sensors must be set up as follows (This is only an example)
