GE IC697BEM713F Bus Transmitter Module

GE IC697BEM713F Bus Transmitter Module

Basic Information

Brand: GE (General Electric)

Origin: United States

Series: PACSystems RX7i

Model: IC697BEM713F

Main Functions and Applications

The IC697BEM713F module serves as a bus transmitter, responsible for efficient data transmission within industrial automation systems.

It is primarily installed on the main CPU rack, usually in the second slot next to the CPU module.

With two interfaces, the top interface can connect to peripheral programming devices, while the bottom interface connects to bus receiver modules, enabling bidirectional data transmission.

Technical Specifications

Data Rate: Up to 500KB/s, ensuring fast and accurate data transmission, which is crucial for real-time control and monitoring in industrial automation systems.

Compatibility: It is important to note that the IC697BEM713F does not support multiple common bus protocols, such as AS-i, CAN, CC-Link, etc. Therefore, when selecting and using this module, it is necessary to ensure its compatibility with other devices or protocols in the system.

Installation and Configuration

The module should be installed on the rack with the power off.

After installation, when the power is turned on, the top LED indicator should flash for about 5 seconds. If the diagnosis is successful, the top LED will remain lit.

The middle LED lights up when the CPU receives a valid configuration for the module and verifies the operation of the IC66* I/O bus.

The bottom LED remains off in all cases.

Price and Availability

The price of the GE IC697BEM713F module may vary depending on the supplier and purchase quantity.

It is recommended to contact authorized GE dealers or distributors for the latest pricing and availability information.

Application Fields

Due to its high performance and reliability, the GE IC697BEM713F module is widely used in various industrial fields, including glass production and processing, chemicals and salt chemical plants, metallurgy, hydropower plants, automobile manufacturing, steel engineering, cement production, power and water conservancy, central air conditioning and building monitoring, water supply and treatment, railway transportation, power stations, papermaking and printing, and more.

Functionality and Features

Bus - Specific Transmission

The primary function of this module is to transmit data over a particular bus type. It is likely designed to work with a specific industrial - bus standard such as Genius Bus or another proprietary GE bus protocol. The module takes in data from a local source, such as a Programmable Logic Controller (PLC) or an input - output (I/O) module, and formats it into a format suitable for transmission over the bus. For example, it might package the data into packets with appropriate headers, addresses, and error - checking bits as per the bus protocol.

Data Encoding and Formatting

The IC697BEM713F is responsible for encoding the data to be transmitted. This could involve converting digital data into a format that can be efficiently sent over the bus. It might use techniques such as Manchester encoding or other encoding schemes depending on the requirements of the bus protocol. Additionally, it formats the data to include necessary information like the source and destination addresses, message type, and data length. This formatting ensures that the receiving end can correctly interpret and process the transmitted data.

Transmission Rate and Timing Control

The module controls the rate at which data is transmitted over the bus. It adheres to the specified data - transfer - rate requirements of the bus protocol. For example, if the bus has a maximum data rate of 1 Mbps, the module will adjust the transmission speed to stay within this limit. It also manages the timing of the data transmission, ensuring that the data is sent in a synchronized manner according to the bus's clock or timing requirements. This helps to prevent data collisions and ensures reliable communication.

Error - Detection and Correction

To ensure the integrity of the transmitted data, the module incorporates error - detection and correction mechanisms. It can use techniques such as cyclic redundancy check (CRC) to detect errors in the transmitted data. If an error is detected, depending on the severity and the capabilities of the bus protocol, it can either request re - transmission of the data or try to correct the error using error - correction - coding techniques. This helps to maintain the accuracy of the data being transferred between different components in the industrial - control system.

Technical Specifications

Bus - Protocol - Specific Specifications

The module is designed to work with a specific bus protocol, and it provides detailed specifications related to that protocol. For example, if it's a Genius Bus - compatible module, it will specify the Genius Bus - version support, the maximum - packet - size allowed (e.g., up to 256 bytes), the supported - message - types (such as read, write, and interrupt - messages), and the bus - access - method (e.g., token - passing or master - slave).

Transmission - Rate Specifications

The maximum and minimum data - transfer - rates supported by the module are clearly defined. For example, it might support data - transfer - rates ranging from 100 kbps to 1 Mbps. The module also provides information about the bit - error - rate (BER) performance at different - transmission - - rates. The BER indicates the likelihood of errors occurring during data - transmission and is an important parameter for assessing the reliability of the communication link.

Electrical - Interface Specifications

The electrical - interface characteristics of the module are specified to ensure proper connection to the bus. This includes the type of connector used (e.g., a multi - pin - D - - type - connector), the pin - - configuration for different - bus - - signals (such as data - lines, clock - - lines, and power - - lines), the input - and - output - - voltage - - levels for the bus - - signals (e.g., TTL - - level or RS - 485 - - level - signals), and the impedance - - matching - - requirements. These specifications help to ensure that the module can interface correctly with other components on the bus and that the electrical - signals are transmitted and received accurately.
