Installing the DriveBus Interface, CI858/TP858
The CI858 is powered from the processor unit via the CEX bus and requires
therefore no additional external power source. The unit is mounted onto a horizontal
DIN rail.
Mount the unit onto the DIN-rail, see Mounting AC 800M Units onto DIN-Rail on
page 65, Installing the PM86x/TP830 Processor Unit in Single Configuration on
page 78 and CI858 and TP858 – DriveBus Interface on page 313.
Optical Connectors
The CI858 board connects to the drive system via three optical receiver/transmitter
pairs. HP/Agilent Technologies Versatile Link Series (HFBR family) optical
transmitter/receivers are used. Transmission speed of the optical fibres is 4 Mbit/s.
