FIP Bus Interface
The Remote I/O Scanner communicates at a data rate of 1MHz. There are two versions of the FIP
communications standard: FIP and WORLD FIP. A DIP switch on the module is used to select the
version that will be used by the Remote I/O Scanner. (The same communications method will then
be used on both bus cables).
The DIP switch on the module must be set to the FIP position for the Remote I/O Scanner to
communicate with a Series 90-70 PLC.
Module Description
The FIP Remote I/O Scanner is a standard Series 90-30 PLC module that plugs easily into the
backplane of the baseplate.
