BTM Connectors

There are two connectors on the front of the BTM board. The top one provides a parallel connection to a Work Station Interface (WSI) board installed in the programmer for the Series 90-70 PLC. Serial connection to Workmaster II is through a programmer cable (IC647CBL703) 10 feet (3 meters) in length (parallel connection to Workmaster is through a parallel I/O cable, IC600WD005A). Standard parallel I/O cables are used to connect the BTM's lower connector to a Redundancy Communications Module in the other Redundancy unit, or to a Bus Receiver Module in the first expansion rack. These connectors are 37-pin connectors. The top one is a male connector, while the lower one is female.

Note

The programmer running Logicmaster 90 Software must be connected to the same power ground as the PLC, unless special isolated drivers are used. The parallel programmer cable should only be connected/disconnected when the programmer is powered-up and offline. Do not power the parallel programmer up or down while connected to a PLC that is running.

Bus Receiver Module

The Bus Receiver Module is required if expansion racks are used in the overall redundancy system.

The Bus Receiver Module (BRM), catalog number IC697BEM711, which must be installed in slot 1 of each expansion rack in a system, is the expansion rack interface to the I/O bus. It provides the link to the I/O bus for I/O modules installed in its rack. The BRM in the first expansion rack connects to the BTM in the CPU rack through a parallel I/O bus cable.

This cable is connected to the bottom connector on the BTM, and to the top connector on the BRM. The next rack to be included in the I/O bus is connected to the lower connector on the BRM in the first expansion rack and the top connector of the BRM in the next rack.

Connection of expansion racks on the I/O bus is continued in this manner until the maximum of 6 expansion racks is connected. The bottom connector in the last expansion rack is connected to the top connector of the RCM in the remote unit. Note that the last bus connection is to an RCM module (instead of a BRM).

Note

The total cable length of all connecting cables between racks on the I/O bus cannot exceed 50 feet (15 meters).
