Introduction

This chapter describes the Series 90t±70 Remote I/O Scanner (IC697BEM733) and other equipment that may be used with it. It discusses Genius bus operation as it relates to the Remote I/O Scanner, and describes how the Remote I/O Scanner can be used in Genius redundancy systems.

Overview

The Remote I/O Scanner is an intelligent module which mounts in a remote Series 90±70 rack, and interfaces Series 90±70 modules to a Genius bus.

The Genius bus connects the Remote I/O Scanner to a Bus Controller in the host PLC or computer. Additional remote drops, Genius blocks, Bus Controllers, and Hand±held Monitors can be attached to the same bus.

I/O BLOCKS

The Remote I/O Scanner can send up to 128 bytes of inputs from input boards in its remote drop to the CPU, and can provide up to 128 bytes of outputs from the CPU to output boards in the remote drop. The amount of data transferred is configurable. Individual I/O circuits in the remote drop can be:

HForced and unforced from a Hand±held Monitor or the application program logic.

HOverridden from a PLC application program.

HToggled from a Logicmaster 90±70 programmer.

The Remote I/O Scanner can be used in CPU redundancy (dual controller) and bus redundancy (dual bus) systems.

The Host CPU

The Remote I/O Scanner is ideally suited for use in a Series 90±70 PLC system. However, any type of PLC or computer capable of controlling a Genius bus can be used as the host. Suitable hosts include Series Six PLCs, Series Five PLCs, and computers equipped with a PCIM (Personal Computer Interface Module), QBIM (Q±Bus Interface Module), or a third±party GENI±based interface.
