Description
The IC697BEM733 Remote I/O Scanner consists of a single circuit board, with a hinged door which serves as a faceplate. The module does not require batteries; the faceplate battery holder is not used.
This module is specifically a Remote I/O scanner, primarily used to implement distributed I/O architecture. This module allows the installation of remote I/O stations which can be located up to 7500 feet or 2275 meters from the host controller. It can be configured to handle any combination of discrete I/O and analog I/O up to a maximum quantity of 1024 Discrete inputs, 1024 Discrete outputs, 64 Analog input words, and 64 analog output words. A remote I/O station that is being communicated with the IC697BEM733 Remote I/O scanner module may contain instances of IC697 discrete modules, analog modules, and analog expander modules. Bus Transmitter, Bus Receiver, PCM, and ADS modules. This module is recommended for use with IC697 modules however, IC66* modules, 3rd party PLCs, and computers installed with Remote I/O communication cards may be used with the IC697BEM733 module.
Applications
Large thermal/nuclear power plants: Connecting boilers, cooling towers, and turbine auxiliary racks across a plant area spanning several kilometers via a Genius bus.
Oil and gas plants: Managing remote I/O stations distributed across different explosion-proof areas or tank farms.
Iron and steel metallurgical plants: Aggregating control signals from multiple large rolling mills or blast furnaces to a central control room in high-temperature, high-electromagnetic-interference environments.
Large municipal wastewater treatment plants: Controlling multiple booster pump stations and sedimentation tanks distributed over an area of several square kilometers.
Features
Can be located up to 7500 feet (2275 meters) from controller.
Supports standard IC697 discrete and analog I/O modules.
Supports PCM, ADS, and analog expander modules.
Handles up to 128 bytes of inputs and 128 bytes of outputs per remote drop.
Configurable with MS-DOS programming software configuration function or with an IC66* Hand-held Monitor.
Compatible with all types of IC66* host.
Supports both CPU and IC66* bus redundancy.
Each remote drop can include up to eight racks, with a Remote I/O Scanner located in rack 0.
Up to 30 remote drops can be located on the same IC66* bus.
Operation
The Remote I/O Scanner scans the I/O modules in the remote drop in the same manner as an IC697 CPU scans the I/O modules in the PLC. At powerup, scanning begins immediately unless a fatal diagnostic error occurs. All I/O in a remote drop, except those that are forced, default to Off at powerup. I/O that are forced at powerup start in the forced state or value.
During operation, the Remote I/O Scanner first scans the input modules in rack and slot order, storing the input data in its own %I and %AI memories. Then, it scans the output modules in rack and slot order, sending them the most recent output data from its own %Q and %AQ memories.
