GE FANUC IC697CMM711 , Single-Slot Communications Coprocessor Module , 90-30 series

Product Description

The IC697CMM711 is a Single-Slot Communications Coprocessor Module (CMM) from the GE 90-30 series. The module comes standard with soft switch configuration (eliminating the need for switches and/or jumpers), three status LEDs, pushbutton reset control, and two serial ports. The module uses a 12 Mhz, 80C186 microprocessor. Additionally, no battery is needed.

The CMM is part of a family of communication modules and demonstrates both communications control (CCM), remote terminal (RTU), and general IC69 communications (SNP) functionality. CCM, RTU and SNP are available on either or both serial ports in any of nine possible configurations: CCM/CCM, CCM/RTU, RTU/CCM, RTU/RTU, SNP/SNP, SNP/CCM, CCM/SNP, SNP/RTU, and RTU/SNP. The module delivers both the RS-232 and RS-485 interfaces and communicates with the PLC CPU via the backplane. Numerous CMMs can be placed in just one IC697 PLC system.

Functions allowed by the IC697CMM711 CMM in the CCM operation mode include read/write of register, input and output tables, bit set/clear of inputs and outputs, read of scratch pad, Q sequence commands for fast reads, and diagnostic status word modification. In master/peer CCM configurations, the CMM initiates communications with remote devices through application ladder program communications requests.

The IC697CMM711 module’s status is viewable via three LEDs. Activity of the serial ports are identified in port 1 LED and port 2 LED. The top LED will blink when the module is powered up, and once diagnostics are completed effectively, the top LED will remain lit. The top LED will always identify module state.

About IC697CMM711

The IC697CMM711 module from GE Fanuc is an industrial communications coprocessor module, also known as a CCM. It is part of GE Fanuc’s Series 90-70 product line of programmable logic controllers or PLC components and accessories. The communication protocols that the IC697CMM711 communication coprocessor module can support are the master, slave, and peer-to-peer CCM protocols, the master and slave SNP and SNPX protocols, and the slave RTU Modbus communication protocol. The module comes with 1 slot and a pushbutton for resetting. It does not need a battery. The IC697CMM711 module does not need jumpers or switches for configuration. Instead, it can be configured with the soft switch configuration method. This communications coprocessor module comes with 2 serial ports that can be RS-232 or RS-422/RS-485 serial ports.

The GE Fanuc Series 90-70 IC697CMM711 communications coprocessor module uses an 80C186 Microprocessor that operates at a rate of 12 Mhz. It is possible to install more than 1 communications coprocessor module in a single programmable logic controller system to maximize the controller system’s communication options. The IC697CMM711 module and all the other CCMs in the PLC system communicate with the PLC’s CPU through the backplane. There are 3 LEDs on this module. One of the LEDs shows the current condition of the module while the other 2 LEDs show the activity of the module’s 2 serial ports. The port LEDs are labeled as the Port 1 LED and the Port 2 LED. This module is made to be installed in a rack, and it should only be installed when the rack power is disconnected.
