Benefits

Connects IC697 I/O modules to the I/O bus of IC600 programmable controllers

Rack-dependent I/O reference Supports up to eight racks per I/O system

Function

The I/O Interface Module to the IC600 Programmable Controller provides the interface between the IC600 I/O bus and the IC697 I/O module.

The I/O Interface Module is mounted on the IC697 chassis and has two 37-pin connectors identical to those on the IC600 I/O Receiver for interconnection to the IC600 I/O bus.

The IC600 PLC system can be configured to include IC600 I/O, IC697 I/O, and IC660 I/O. The IC600 and IC697 I/O racks can be included in one I/O chain.

Each IC697 I/O rack can be assigned 128 (five-slot rack) or 256 (nine-slot rack) I/O reference points.

Up to eight of these racks can be used in a system, providing up to 2000 addressable points.

Addressable points. Any point can be used for input or output.

A minimum of 8K registers are required in the IC600 www.cniacs.com PLC for the I/O interface module to operate.

Module Operation

The I/O Interface Module is an intelligent module that allows the IC697 I/O Rack to interface with the IC600 I/O Link Port.

In operation, the I/O Interface Module reads/writes data from each I/O module in the rack. It exchanges data with the IC600 CPU via the I/O bus.

An I/O chain can include up to eight IC697 I/O racks as well as other IC600 racks.

Each IC697 rack has nine or five slots, one for I/O interface modules and eight or four for I/O modules.

While the IC697 I/O modules themselves may have 16 or 32 points.

While the IC697 I/O modules themselves may have 16 or 32 points, each of the eight available I/O slots in the IC697 chassis is allocated 32 discrete points.

Therefore, a nine-slot rack filled with 32-point modules will have 256 points (128 points for a five-slot rack).

The maximum system capacity is 2000 points (896 points for a five-slot rack).

Table 1 shows the I/O mapping by rack and slot.

I/O interface modules must be plugged into slot 1 (next to the power supply slot), with slots 2 through 9 reserved for I/O modules.
