The VME Integrator Rack for the IC697 Programmable Logic Controller can be used for 3rd party VME modules and all IC697 CPU and I/O configurations, except redundancy applications. This rack has a 17-slot backplane and is designed to provide easy integration of 3rd party VME modules into an IC697 PLC system. Integration of 3rd Party VME modules must be in accordance with guidelines which are described in the User’s Guide to Integration of 3rd Party VME Modules. Backplane connectors are spaced on 0.8 inch centers to accommodate 3rd party VME modules. IC697 modules each use two of these slots. Standard IC697 racks have slots spaced on 1.6 inch centers for IC697 modules. VME modules that require 0.8 inch spacing for installation in a rack may not fit in the standard IC697 racks (IC697CHS750/790/791).
