The notification message also contains controller name, serial number and textual description of the
event.
SMI version
In InteliConfig the MIB table may be exported in two different formats – SMI v1 and SMI v2. The format which
shall be used for export depends on the SNMP Manager and the SMI version that it supports. Typically, SMI
v1 is used for SNMP v1 and vice versa, but it is not a rule and SMI v2 may also be used for SNMP v1.

6.2.2 MODBUS-RTU, MODBUS/TCP
MODBUS protocol is used for integration of the controller into a building management system or for remote
monitoring via 3rd party monitoring tools.
MODBUS-RTU can be used on serial interfaces (via on board RS485 connector or via CM-RS232-485
communication module). The MODBUS-RTU server must be activated by switching the setpoint
or
into the Modbus position. The serial speed for MODBUS-
RTU communication is adjusted by the setpoint
COM1 MODBUS Communication Speed (page 331)
or
COM2 MODBUS Communication Speed (page 333)
MODBUS/TCP can be used on the Ethernet interface (CM3-Ethernet module is required). Up to 2 clients
can be connected simultaneously. The MODBUS/TCP server must be activated by the setpoint
MODBUS, MODBUS/TCP protocol can be used simultaneously with Web connection and direct Ethernet /
AirGate connection.
IMPORTANT: Do not use setpoints for regulation purposes. Avoid fast periodical re-writing of any
setpoint. Use remote control registers instead.
Note:
Modbus-RTU serial communication mode is 8-N-1 – startbit 1, 8 data bits, no parity and 1 stopbit.
Address space
The object address space is separated into several areas as described in the table below. The actual
mapping of specific controller data objects to specific Modbus addresses, which depends on configuration,
