The FIP (Factory Instrumentation Protocol) Remote I/O Scanner (catalog number IC693BEM330)
is an intelligent module that interfaces Series 90-30 I/O modules to a FIP bus. Up to 19 I/O
modules can be accommodated by using two 10-slot baseplates connected by an expansion cable.
Together, the Remote I/O Scanner and the modules it serves are referred to as an I/O Nest. The FIP
Nest can include most Series 90-30 I/O modules
