2.10.1 Interfaces

CP9xx devices communicate with the devices and systems assigned via various interfaces:
Internal BMS bus (RS-485) for Bender systems such as EDS46x/49x, RCMS46x/49x and MEDICS.

CP9xx devices can be operated as a master or as a slave. When operated as a master, requests
are answered more quickly. The devices can only be operated on the internal BMS bus.
BCOM for new and future Bender systems, such as ISOMETER® iso685-D.

Modbus RTU (RS-485) when operated as a master for Bender universal measuring devices PEM..3

and also PEM..5 with restricted functionality (full functionality of PEM..5 only via Modbus TCP).
Modbus TCP (Ethernet) for Bender universal measuring devices PEM..5

2.10.2 Process image

The CP9xx alarm indicator and operator panel combines the information from the different interfaces and ma-
kes it available for operation and visualisation via the web user interface of a PC.
It acts as a central user interface. In order to be able to identify them, one individual address is available for each
device on this interface. BMS, BCOM and Modbus RTU devices receive the appropriate address for their inter-
face. A virtual address is assigned to Modbus TCP devices.
