BB bus
The BB bus is an interface which enables Bender devices to communicate
with each other (Bender-internal device bus).
The BB bus can be used with an ISOMETER® and one or more EDS44…-S.
BCOM
Protocol for communication between Bender devices via an IP-based
network.
BS bus
The Bender sensor bus is an interface which enables Bender devices to
communicate with each other (RS-485 interface).
DHCP
Dynamic Host Configuration Protocol. It is used to assign the network
configuration to Clients via a server.
ISOnet
Only one ISOMETER® may exist in an isolated system. If several networks
monitored by an ISOMETER® are coupled, this function ensures via an
Ethernet connection that only one ISOMETER® is actively measuring.
ISOnet priority
This function makes it possible to give permanent priority to a device in
ISOnet mode or to get priority.
After 12 hours, the device returns to normal mode.
ISOloop
Special function for ring systems (all systems are coupled). The ISOloop
mode is activated via the information of the dig. input (switch state). If all
devices are in this mode, the device with the lowest BCOM address con-
tinues to measure.
Modbus TCP
Modbus is an international widely spread protocol for data transfer via
TCP/IP.
Modbus RTU
Spread protocol for data transfer via RS-485 protocol.
System (BCOM)
The system is the entire installation that is visible for the customer and
defined by the customer. The BCOM communication takes place within
this system. Naturally, different systems can exist independently in one
network.
Subsystem (BCOM)
The subsystem structures parts of the system as units defined by the cus-
tomer, e.g. all PQ devices. A typical subsystem are also "non BCOM-capa-
ble" devices that are hidden behind a proxy.
Webserver
A web server presents the device functions graphically. The web server
can be used for reading out measured values and for parameter setting.
