The IC693CMM302 is a Genius Communication module belonging to the
Series 90-30 Programmable Logic Controller (PLC)
series of Emerson Automation, formerly by GE Fanuc automation. This
module is a single-slot width module, providing Genius
protocol connectivity, enabling communicating with up to 31 devices
and a maximum of 62 devices per controller as the Series
90-30 systems permit configuration of up to Two (2) IC693CMM302 per
controller. The IC693CMM302 allows 128 bytes of
transmitted and 128 bytes of received Global data per IC693CMM302
and supports PLC registers such as Global register (%G),
Discrete Input (%I), Discrete output (%Q), Analog input (%AI),
Analog output (%AQ), and Register memory (%R). It supports
software-based diagnostics such as status bits, fault reporting to
series 90-70 PLC. Environmental ratings of this module include
0 oC to +60 oC (+32 oF to +140 oF) operating temperature; Storage
temperature of –25 oC to +70 oC (– 13 oF to +158 oF);
Humidity of 5% to 95% (non–condensing) while the mechanical ratings
include 0.2-inch displacement 5Hz to 10Hz and 1 G
10Hz to 200Hz operating vibration and operating shock of 5 G 10Ms
duration. Aside from Global data exchange, the
IC693CMM302 allows data monitoring through a personal or industrial
computer, monitoring data with the use of I/O blocks,
device communication over the Genius bus, and I/O emulation. The
IC693CMM302 has a backplane power consumption of
<300 mA at 5VDC. Aside from Series 90-30 PLC, it can be used
with Series 90-70, Series Six PLCs as well as the Genius
Hand-Held Monitor (HHM) for local configuration.
The Series 90-30 IC693CMM302 communication module was designed and
manufactured by GE Fanuc to be a GCM+ device,
also known as an enhanced Genius communications module. The
IC693CMM302 enhanced Genius communications module can
communicate with global data between up to 32 devices. These
devices are a GE Series 90-30 PLC and 31 other devices that
are connected to a genius bus. It is recommended to install the
IC693CMM302 enhanced Genius communications module on
the CPU baseplate of the host PLC system for the most efficient
operation, but it can also be installed on the remote baseplates
or the expansion baseplates in the same system. However, enhanced
Genius communications modules cannot be installed in
PLCs that have regular Genius communications modules or GCMs in
them.
Multiple enhanced Genius communications modules like the
IC693CMM302 module can be installed in a single PLC system, and
each enhanced Genius communication module has its own genius bus,
which means that each of these modules can connect to
and communicate with up to 31 additional devices at a time. For
example, a Series 90-30 GE PLC that has 2 enhanced Genius
communications modules in it can communicate with as many as 62
additional devices at a time. The IC693CMM302 enhanced
Genius communications module is primarily used to exchange global
data, but it can also handle data monitoring with an
industrial or personal computer, peer-to-peer communication and
master-slave communication between the bus devices, and
data monitoring from the genius I/O blocks (note that the
communications module cannot control these I/O blocks.
