IC697BEM721 - I/O Link Interface Module

Description

Description: The GE Fanuc IC697BEM721 I/O Link Interface Module for the Series 90-70 IC697 PLC system provides a high-speed serial interface between GE IC697 PLCs and CNC-compatible serial I/O links on the GE Fanuc I/O Link, and it has 1.3 Amps of backplane current draw at 5 Volts DC. This module also has dual RS-422/485 serial ports and 3 LED status indicators.

Technical Specifications for IC697BEM721

The GE Fanuc IC697BEM721 Series 90-70 I/O Link Interface Module provides a high-speed serial interface between Series 90-70 IC697 PLCs and CNC-compatible serial I/O link on the GE Fanuc proprietary I/O Link. The proprietary GE Fanuc I/O link offers high-speed I/O data exchange between connected field devices (especially a master device and up to 16 slave devices). The IC697BEM721 I/O Link Interface Module offers a maximum I/O serial connection distance of 10 meters, but using a fiber cable and an optical module can increase the maximum cable distance to 100 meters. Each GE Fanuc IC697 PLC controller can hold 4 I/O link modules in both master or slave modes and separate I/O links. In the master mode, the IC697BEM721 I/O Link Interface Module can support 1024 discrete I/O points with slave devices like IC693 PLCs, Power Mate CNCs, or Series 0 CNCs, and it also supports up to to 64 discrete I/O with master devices in slave mode like a second IC697 PLC in the I/O link, an F-D Mate CNC, a Series 0 Model, a C Series 16, a Series 15, or a Series 18 CNC device. The GE Fanuc Series 90-70 IC697BEM721 I/O Link Interface Module can be installed in any slot of the IC697 PLC rack except slot 1 which is reserved for the CPU module, and it can be configured with Windows-based application software that lets the operators set up the I/O link, assign a location for the input and output data to and from the I/O link, provide diagnostics capabilities for the I/O link, and integrate with the rest of system application program. The IC697BEM721 I/O Link Interface Module comes with two 20-pin D-type connector RS-422 and RS-485 serial ports for connecting to the I/O link, and it also has 3 LED indicator lights that shows its current operation and communication status to the operators.

The communication module of the programmable controller is equivalent to the network interface in the local area network. The communication module data bus is connected to the PLC host, and the communication protocol is realized by hardware and software. The communication module of the programmable controller is generally provided with multiple interfaces, which can be selected through the selection switch on the communication module to realize the communication with other programmable controllers, intelligent control devices or computers. The input module is used to receive and collect input signals. There are two types of input signals: one is the switch input signal, which is provided by the button switch, the travel switch, the digital dip switch, the proximity switch, the photoelectric switch, the pressure relay, etc. The other is a continuously varying analog input signal sent by a potentiometer, thermoelectric meter, tonometer, motor, and various transmitters. The input module also needs to convert these different level signals into digital signals that the CPU can receive and process. The function of the output module is to receive the digital signal processed by the central processor and convert it into a signal that can be received by the field executive parts for controlling contactors, solenoid valves, regulating valves, speed regulating devices, etc. Another type of load control is the indicator light, digital display and alarm device.
