APPENDIX C
PA/4000 Remote I/O (P/N 6100-121) Configuration
This section covers the configuration and usage of the Diagraph Remote I/O (RIO)
module board in the PA/4000 with an Allen-Bradley PLC. For successful implementation,
you should be able to program and operate an Allen-Bradley PLC and be able to program
block transfer instructions. You will also need access to the PA/4000 host commands and
their parameters.
Minimum Requirements
Rack: One quarter
Power Supply: Allen-Bradley
PLC: Allen-Bradley (see the compatibility list in section 5.2.4)
Cables: Power cable to PLC power supply
PLC to Diagraph RIO board-Belden 9463 with Phoenix connectors
PC to PLC-RS-232
Optional (Ethernet connection from PC to PLC, useable with A-B PLC
model 5/11 or higher)
Controller: PC with Allen-Bradley 6200, Release 5.0 software or other software
capable of programming PLCs.
Communication Specifications
Cable Type
Use Twinax cable to connect the PLC to the RIO board-Belden 9463 blue PVC jacket
cable (Allen-Bradley P/N 1770-CD). Contact Allen-Bradley if other cable is under
consideration.
Cable Length
Use a minimum of ten feet for all connections. Shorter lengths may cause signal
reflections. Maximum lengths depend on the RIO data rate: 10,000 feet for 57.6k bit/s
and 5,000 feet for 115.2k bit/s.
Contact Allen-Bradley if you are considering an application that will employ a data
rate of 230.4k bit/s.
Cable Connections
Use three position MSTB plugs (Phoenix P/N
1754465 or equivalent) for connections to the PLC
and to the RIO board. Connect all three conductors-
blue, shield and clear-at each wiring point and avoid
making additional ground connections to the shield.
