Installing the Ethernet Interface for MasterBus 300,
CI855/TP853
The CI855 is powered from the processor unit via the CEX-bus and requires
therefore no additional external power source.
The baseplate, TP853, provides two Ethernet ports for connection of redundant
Ethernet network for MasterBus 300.
Use the following procedure to install the CI855/TP853:
1. Mount the unit on the DIN-rail, see Mounting AC 800M Units onto DIN-Rail
on page 49 and Installing the PM8xx/TP830 Processor Unit in Single
Configuration on page 56.
2. Connect the Ethernet twisted pair cable to the contact on the baseplate.
3. Connect the other end of the Ethernet cable to a HUB.
Ethernet twisted pair Connection
The Ethernet twisted pair is connected via the 10 Base-T RJ45 connector located on
TP853. For a description of the connector, see Table 8 on page 62.
If the Ethernet cable has a transceiver, the connector from the transceiver must be
converted to RJ45. The communication unit, CI855, can not provide power to the
transceiver, therefore a separate power source must be used.
