1. User Features
The RX3i Genius Communications Gateway,
IC695GCG001, or GCG001, interfaces Genius I/O
devices on a Simplex Genius serial bus to a GE’s
Automation & Controls PROFINET I/O Controller or
CPE330 CPU
†
. The GCG001 operates as a Genius
Bus Controller on a Genius network. It scans the
Genius I/O devices configured to it, retrieving input
data and providing output data, and exchanges
that data with its configured PROFINET I/O
Controller over its Ethernet interfaces at the
configured production rate. If the Ethernet network
or Genius serial bus communications are lost, the
GCG001 manages I/O states according to the
individual module configurations. The GCG001 can
manage communications for up to 31 Genius I/O
devices on a single Genius Serial Bus.
1.1. Ethernet Ports
The GCG001 provides two RJ-45 Ethernet ports for
connection to a GE PROFINET controller. Although
the hardware supports the 10/100BASE TX
Ethernet standard, PROFINET I/O over wired infrastructure must be 100Mbps full-duplex or
faster. 10Mbps should not be used for PROFINET. Each port automatically detects the
attached cable and functions properly with either straight-through or crossover cables.
†
In addition to the PNC001, beginning with version 8.90, the CPE330 CPUis capable of controlling a
GCG001 on a PROFINET network. No other PROFINET controllers are supported.

Each port on the GCG001 operates independently through an embedded Ethernet switch.
The switch permits the network to be daisy-chained through the GCG001 to other I/O
devices.
1.2. Genius Serial Bus Connector
The GCG module is equipped with one active sixterminal Genius Serial Bus connector. Two terminals
each are provided on a removable terminal block
connector for Serial 1, Serial 2, and Shield connections.
When the bus is terminated at the GCG001, a bus
termination resistor should connect Serial 1 to Serial 2,
with SHLD OUT unterminated.
When the GCG001 is not at the end of the bus, the two
sets of terminals accommodate two bus cables as
shown at right. The Genius bus will continue to
operate even in the absence of power to the GCG001.
(Removing the connector, however, will disrupt the
Genius bus.)

1.3. Power Connector
The module requires a user-supplied 24 Vdc (±10%)
power source wired to a removable screw-terminal
block located on the bottom of the module. The
module draws 0.2 A maximum current.
1.4. Rear of Module Features
Two seldom-needed features are accessed from the rear of the module: an SD card slot and
a firmware load pushbutton. These are described in the following paragraphs.
Secure Digital (SD) Card Slot
The SD card slot is designed to support a Secure Digital (SD) non-volatile memory card in
standard capacity format. This optional card has two distinct uses: (1) backup storage of
some key PROFINET configuration data and (2) loading new module firmware.
Backup Storage
For use as configuration back-up storage, a small SD card is inserted and left in place. The
module will detect the card automatically and store on it a small amount of configuration
data. If the GCG001 must be replaced in the event of a failure, remove the SD card from the
failed unit and install it in the replacement prior to mounting. All PROFINET configuration data
will then be transferred to the replacement module.
Note: SD cards larger than 2 GB are not supported for use with with the GCG001. SDHC
and SDXC formats are not supported.
