CI857 and TP853 – INSUM Interface
Key Features
• Provides one Ethernet port, (RJ45 connector located
on the TP853 Baseplate). Only COM1 is used for
INSUM.
• Simple DIN-rail mounting
• Provides communication with INSUM via
Ethernet/LON Gateway
• Pre-set, two-letter Alpha code locking device
installed in unit base prevents mounting of
incompatible components.
Description
The CI857/TP853 can be used to connect an AC 800M
controller to INSUM through TCP/IP over Ethernet and
an INSUM TCP/IP Gateway that has a LON interface
communicating with the underlying INSUM system.
The TP853 Baseplate has two RJ45 Ethernet connectors,
though only the COM1connector is used for connecting
to INSUM.
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 CI857 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.
