For additional information on designing a fieldbus (connectors, cables and devices), see fieldbus documentation. A catalog referencing suppliers, devices, services and other fieldbus-related items, is available for FIELDBUS ONLINE via the Internet web site. Powering Field Devices Field devices requiring power from the fieldbus need special power supplies connected to the data wires (in the same way as a field device). To avoid shortcircuiting of fieldbus signals, use only power supplies with impedance characteristics specifically designed for FOUNDATION Fieldbus. Do not use SD82x power supply units for this purpose. Note that there is no unit redundancy for the CI852 unit. Cannot be used in High Integrity Controller. CI852 has been replaced by the CI860 communication interface. CI852 is only described for legacy reasons. It is not possible to change the CI852 unit via hot swap and it is not allowed to perform an online upgrade of firmware in a system containing CI852.

Installing the RS-232C Interface, CI853/TP853 CI853 is powered from the processor unit via the CEX bus and requires therefore no additional external power source. Use the following procedure to install the CI853/TP853: 1. Mount the unit onto the DIN-rail, see Mounting AC 800M Units onto DIN-Rail on page 65 and Installing the PM86x/TP830 Processor Unit in Single Configuration on page 78. 2. Connect the cable (maximum 15 m (16.4 yd)) to one of the contacts on the baseplate. Connect the cable screen to the ground terminal within the connector to ground the screen via CI583. 3. If cables longer than 15 m (16.4 yd.) are required, then a short distance modem TC562 must be used. In this case mount the modem onto a DIN-rail in a suitable position, connect a 24 V DC power supply to the modem and connect cable TK853 from CI853 to the TC562 modem input terminals 4. Connect the TC562 modem output terminals to the outgoing cable. The TC562 modem can be used for the following distances/speeds: • Up to 1000 m (1100 yd) with transmission speed 19200 bit/s • Up to 12000 m (13100 yd) with transmission speed 1200 bit/s Connectors Connect the RS-232C channels to the RJ45 connectors marked COM1 and COM2 on the TP853 Baseplate.
