1.4 Description
The RX3i Genius Communications Gateway, IC695GCG001 (or GCG001), interfaces Genius IO devices on a
Simplex Genius Serial Bus to a GE PROFINET IO Controller.
Figure 1: Simplex PLC System Using Genius Gateway GCG001
The GCG001 operates as a Genius Bus Controller on a Genius network. It scans the Genius IO devices
configured to it, retrieving input data and providing output data. It then exchanges that data with its configured
PROFINET IO Controller over its Ethernet interfaces at the configured production rate. The GCG001 can
manage communications for up to 31 Genius IO devices on a single Genius Serial Bus.
The GCG001 also operates as an IO Device on PROFINET. It may be controlled by any of the following PROFINET
IO Controllers:
•PNC001 (the RX3i rack-mounted PNC module), or by
•CPE330 LAN 2 when configured as a PROFINET LAN, or by
•CPE400 LAN 2 when configured as a PROFINET LAN.
Thus, when correctly configured, the entire Genius Bus, including the GCG001 itself, becomes visible to the
controlling PLC. Note that the GCG001 operates only with GE PLC PROFINET IO Controllers.
PROFINET operates on an Ethernet network. If the Ethernet network or Genius serial bus communications are
lost, the GCG001 manages I/O states according to the individual module configurations.
Both PROFINET and Genius may be set up in Redundant configurations. These are discussed later in this
manual.

Configuration
GSDML file is available on the Support website for download and
import into PME. The GSDML supporting a firmware release is part
of the firmware upgrade kit available on the Support website.
Hot Swappable
The Genius Gateway requires an external 24Vdc power supply
and does not draw power from the Rx3i backplane. Swapping out
the GCG001 will therefore not impact the PLC. However, this
cannot be performed without disconnecting its power supply. If
configured to support Genius Hot Standby, the loss of a single
GCG001 will be tolerated; otherwise not.
For system standards, general operating specifications, and installation requirements, refer to the PACSystems
RX3i System Manual, GFK-2314.

Mounting
The GCG001 may either be panel-mounted or be mounted in the rightmost slot (expansion slot) of an RX3i
rack (IC695CHS012 or IC695CHS016).
Note: The SD Card supplied with the GCG001 will have been installed at the factory. See
section 2.4.1 for instructions for installing the SD Card when doing a retrofit. The
presence of the SD Card should be checked before mounting the module.
Note: Clearance of 3 inches (75mm) must be provided above and below the module for proper
ventilation and to permit cable access.
Note: External power must always be supplied to the module, regardless of which mounting
arrangement is chosen. When rack-mounted, the GCG001 does not draw power from the
RX3i Universal Backplane.
RX3i Backplane Mounting
The GCG001 may be mounted in the rightmost slot
(expansion slot) of an RX3i Universal Backplane.
The two captive M3.5 screws at the rear of the GCG001
align with mating tapped holes on the right side of the
backplane, providing a convenient mounting location.
When rack-mounted, the module does not make contact
with the backplane connector.
Panel-Mounting
Panel-mounting allows for mounting where no RX3i
backplane slot is available. The two captive M3.5 machine
screws on the GCG001 can be used for attaching the unit
to a panel.
Note: The panel must have a minimum
thickness of 2.4mm (0.094in).
1. Drill two mounting holes using the spacing
shown in the drawing (at right) and tap for
M3.5 (3.5 x 0.6mm).
2. Align the two mounting screws of the module
with the mounting holes in the panel.
3. Using a Philips screwdriver, tighten the two
screws to a maximum torque of 0.5 Nm
(4.4 in-lbs).

1.8 PROFINET Operation Overview
An RX3i Genius Communications Gateway (GCG001) uses PROFINET communications for data exchange with
the PLC. As noted above, the data rate must be 100Mbps full-duplex or faster. The same network may be used
for basic Ethernet communications, but use of a separate Ethernet network and RX3i Ethernet interface is
recommended.
PROFINET Communications
Communications on an RX3i PROFINET network use the standard PROFINET communications described in this
section. Note, however, that the Genius Gateway GCG001 is constrained to work only with GE PROFINET PLC
products.
Application Relationships
Before a PROFINET IO-Controller can exchange data with a PROFINET IO-Device such as the GCG001, an
Application Relationship (connection) must be established between the devices. The PROFINET IO-Controller
automatically sets up the correct number and types of Application Relationship and Communication
Relationship channels (see below) based on its PME configuration. Usually, only one Application Relationship is
established per IO-Device.
Communication Relationships within an Application Relationship
Within each Application Relationship, the PROFINET IO-Controller establishes the following types of
Communication Relationships (CRs):
Record Data CRs –always the first to be established within an Application Relationship. Record Data
Communication Relationships are used for non-real-time transfers of data records such as startup parameter
data, diagnostics data, identification data, and configuration data.
IO CRs –used for the real-time, cyclic transfer of IO data
Alarm CR –used for real-time, acyclic transfer of alarms and events
The following illustration represents an Application Relationship between an RX3i PROFINET Controller and an
RX3i Genius Gateway GCG001.

Figure 6: Real-Time & Non-Real-Time Data Types
Real-Time (RT) communication: PROFINET real-time communication is used for time-sensitive data. A
PROFINET IO-Controller (PROFINET Controller) and PROFINET IO-Device use two types of real-time
communications to exchange data: cyclic communication and acyclic communication:
Real-time Cyclic communication is used to periodically transfer the application’s input and output data. Cyclic
communication occurs each PROFINET IO production cycle.
Real-time Acyclic communication is used to transfer non-periodic data such as alarms. Acyclic communication
occurs only when needed.
Non-Real-Time (NRT) communication: PROFINET non-real-time communication is used for less time-
sensitive data such as configuration, parameterization, diagnostics, and identification data.
Operations of the Genius Communications Gateway
The Genius Communications Gateway performs the following operations:
Consumes PROFINET IO-Device configuration from the PROFINET IO-Controller over the PROFINET network.
Scans input data from each Genius device it manages and produces that data to the PROFINET IO-Controller.
Consumes the output data that it receives from the PROFINET IO-Controller and applies it to each Genius
device it manages.
Where needed, translates Genius Datagrams (background traffic) into PROFINET packages that are sent to the
PROFINET Controller. This includes Datagrams that originated at the Genius Devices, such as Fault Reports.
Translates PROFINET packages that are sent by the PROFINET Controller into Genius Datagrams. This includes
Datagrams that originated at the PLC through use of COMMREQ or Data_Init_Comm instructions. For example,
a COMMREQ is used to generate a Clear Fault Report datagram.

IO Scanning
In the PACSystems RX3i PROFINET network, multiple IO cycles run asynchronously and independently. Figure 7
illustrates typical cycles in a system with an RX3i CPU with a PROFINET Controller module communicating with
a Genius Communications Gateway. Cycles may be different for third-party devices.

Genius IO-Device Scan: In this example, each GCG scans all of its Genius devices. The GCG stores the devices’
input data into its internal memory. Every time the GCG gets a turn on the Genius bus, it transmits the output
data from its internal memory to each of the Genius devices.
3rd party devices: The transfer of IO data between an IO module and the PROFINET IO network is device
dependent. Refer to the third-party manufacturer documentation for specifics for a particular device.
PROFINET IO Production Cycle: Each PROFINET Controller and IO-Device publishes data from its internal
memory onto the network at its scheduled PROFINET production cycle (Note: Production cycles between
IO-Controllers and IO-Devices are not synchronized; each publishes at its configured update rate
independently). The PROFINET Controller publishes output data received from the RX3i CPU to each IO-Device,
and the IO-Device publishes input data from its memory to the PROFINET Controller.
RX3i CPU Sweep: The RX3i CPU Sweep includes both an input scan and an output scan. The CPU input scan
retrieves the current input data being stored within the PROFINET Controller module. This input data is then
available for use by the application logic. After the logic solution, the CPU output scan writes the outputs to the
PROFINET Controller.
