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.
