3.6.2 Process image
The gateway prepares and saves a process image from the communication with the devices as-
signed. This process image contains alarms, status information and measured values from the devic-
es assigned.
The gateway combines the information from the different interfaces and makes it available for:
Operation and data display via the web user interface on a PC
Transfer to external data display programs or PLCs using Modbus TCP or PROFIBUS DP.
The COM465… provides a common user interface for the devices assigned via different interfaces.
On this user interface each device is given an individual address using which it can be identified.
BMS, BCOM and Modbus RTU devices (PROFIBUS DP devices with the COM465DP) receive the ad-
dress necessary for their interface. Modbus TCP devices are assigned a virtual address.
COM465DP only: The gateway is a slave on the PROFIBUS DP. For this reason only the gateway can
be represented as a PROFIBUS device.
3.6.3 List of BMS devices compatible with the COM465…

3.7 BMS side of the COM465…
Internal and external BMS bus
The majority of Bender devices communicate via the internal BMS bus. Individual devices, such as
MK800, TM 800 or Bender panels can communicate via both the internal BMS bus (BMS i) and the ex-
ternal BMS bus (BMS e).
The COM465… is capable of communicating either via the internal BMS bus (BMS i) or the external
BMS bus (BMS e). The related protocol must be set on the menu "Interface" > "BMS".
If the COM465… is operated on the external bus, it is not possible to set the parameters on any other
bus devices. The parameters on the COM460IP itself can, however, can be set via the LAN connected.
COM465… can be operated as a master or as a slave.
COM465… is to be operated as a master if
- Parameters are queried or changed
- Or certain control commands are issued
Please note that not all BMS masters can surrender their master function!
