Installing the TRIO Fieldbus Interface CI862

The CI862 is powered from the processor unit via the CEX-Bus and requires no

additional external power source. No field device is powered from the CI862.

Use the following procedure to install the CI862:

1. Mount the unit onto the DIN-rail.

2. Connect the field bus cable to the LAN connector (right most connector). See

the CI862 Installation book for TRIO field bus guidelines, cable types and

length.

The Hand-Held Monitor, if used, is connected to the HHM connector.

Unit to Baseplate Alpha Code Lock

The CI862 unit and baseplate have the locking device removed because of the

placement of the electronics inside the unit. The electronics will not allow the CI862

unit to be installed in any baseplate with a locking device. However, other units

could be inserted into the CI862 baseplate.

Bus Termination

The appropriate terminating resistor must be attached to both the beginning and end

of the bus. The characteristic impedance for each type of cable is listed in Table 150.

If the CI862 is at either end of the bus, the characteristic resistance is set by a switch

on the Field Bus Interface Module, Table 16. If a TRIO module is at the beginning

or end of the bus, the bus can be terminated with a resistor or a terminating

resistance plug, 6202FP00150 for 150 W or 6202FP00075 for 75 W. BSM stubs

should not be terminated.

The CI862 baseplate has no locking device. Insert only the CI862 unit into this

baseplate. Insertion of other unit types may cause damage to the equipment.
