CI855 and TP853 – Ethernet Interface for MasterBus 300
Key Features
• Provides two Ethernet ports, (two RJ45 connectors
located on the TP853 Baseplate).
• Simple DIN-rail mounting
• Provides Redundant Ethernet networks for
MasterBus 300.
• Pre-set, two-letter Alpha code locking device
installed in unit base prevents mounting of
incompatible components.
Description
The CI855/TP853 can be used to connect an AC 800M to
single or redundant MB 300 Networks. This allows
DataSet communication and transmission of time
between AC 400 Master and AC 800M. The TP853
Baseplate has two RJ45 Ethernet connectors for
connecting to MB300. The baseplate has a code lock, see
Table 6 on page 54, that prevents the installation of an
incorrect type of unit onto the TP853 Baseplate.
The CI855 expansion unit contains the CEX-bus logic, a
communication unit and a DC/DC converter that supplies
appropriate voltages from the +24V supply, via the CEX-
bus. The Ethernet cable must be connected to the main
network through an Ethernet HUB.
