Introduction Chapter 1
This manual describes the RX3i Genius Communications Gateway, which acts as a gateway
between PROFINET and Genius I/O. Introductory material may be found in this chapter.
Chapter 2 provides installation and set-up information. Chapter 3 provides configuration
instructions. Chapter 4 describes system operation. Chapter 5 provides diagnostic
information. Chapter 6 covers the use and format of ladder logic COMMREQ instructions.
1.1 Description
The RX3i Genius Communications Gateway, IC695GCG001 (or GCG001), interfaces Genius IO
devices on a Simplex Genius Serial Bus to a GE Intelligent Platforms PROFINET IO Controller.
Figure 1: 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, controlled by the PROFINET IO
Controller (PNC001 or CPE330 LAN 2) to which it is attached. 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.

Chapter 1. Introduction
1.4.1 Mounting
The GCG001 may either be panel-mounted or mounted in the rightmost slot (expansion slot)
of an RX3i rack (IC695CHS012, 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).

1.5 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 Proficy
Machine Edition (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.

Types of PROFINET Communications
Genius Communications Gateways use two types of PROFINET communication transfers: realtime and non-real-time. The illustration below shows real-time communications as solid lines
and non-real-time communications as dashed lines.
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.
Figure 7: PLC - GCG - Genius Scan Cycles
• 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.

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.

Chapter 1. Introduction
Media Redundancy Protocol Support
PROFINET Media Redundancy Protocol (MRP) supports devices configured in a ring topology.
MRP is specified as part of IEC62439 and has been adopted by the PROFINET specification,
which provides for convenient configuration of the ring topology and necessary parameters.
Like PROFINET IO data, Media Redundancy Protocol operations are not routable between
different IP subnets.
Each device within an MRP ring has two physical pathways to the IO-Controller. To connect to
the ring, each device requires an integrated switch with at least two external ports (ring ports)
that support MRP. Devices that are not MRP-capable can be connected to a device in the ring
(i.e., an MRP-capable switch in the ring), but they should not be in the ring themselves. The
redundancy capability offered by the ring topology only extends to the devices on the ring
that are MRP-capable and enabled.
One of the devices on the ring must be configured as the Media Redundancy Manager (MRM),
and all the other devices must be configured as Media Redundancy Clients (MRCs). The
GCG001 can be configured as an MRC. Configuring the GCG as an MRC alters how the
Ethernet ports connect to the network. They attempt to indicate their state to the MRM before
allowing traffic to flow between the ports and close the ring topology through the internal
switch. They also send out notifications to the MRM when a port is lost. Operation of the
GCG001 is otherwise unchanged.
The MRP configuration is stored in non-volatile storage in the GCG001 and activated
immediately upon powering up. Non-volatile storage is updated as part of a connection with
the IO-Controller. A PROFINET Discovery & Configuration Protocol (DCP) Reset disables MRP
Client operation and updates non-volatile storage. The current state of the MRP configuration
is provided as part of the GCG’s Gateway Status Bits which are accessible to user application
logic. Refer to the description of Gateway Status Bits in Section 5.1.1 for further details.
Fast ring-break detection is not fully functional until all MRP clients have received their MRP
configuration. For a discussion of ring-break detection, refer to the following section,
Bumpless Operation with MRP.
Bumpless Operation with MRP
The GCG001 supports bumpless operation under MRP.
1.6 System Limits
IO-Controllers have limitations on the size of the system they support. One of these limits is
the number of PROFINET sub-modules supported. The GCG001 uses four sub-modules: two
for basic operation and two built-in port sub-modules that are always configured. Each
Genius device attached to a GCG001 uses one additional sub-module.
Other limitations, such as the configuration and IO sizes are specific to the configuration
options chosen. Note that not every combination of options is supported in every system. If
the configuration uses all Genius bus slots with a corresponding large device count, the
memory of the IO-Controller system will be a limiting resource.
See GFK-2571 for actual limits in the RX3i PROFINET Controller (PNC001).
See GEK-90486, Genius I/O System and Communications User's Manual for information on how
much I/O, and which type of I/O, need to be allocated to Genius devices,
Machine Edition (v8.0 or later) takes into account both system limits and I/O allocation.

Chapter 1. Introduction
1.7 Operational Differences vs. Genius Bus Controller
Persons migrating from a Genius environment where the Genius Bus Controller performs
functions similar to those of the GCG001 will want to be aware of the following differences:
1. COMMREQ function block SYSID and Task parameters change. SYSID is now the rack &
slot of the PNC connected to the GCG001. Task is now 132.
2. COMMREQ data blocks are different, mainly due to added PROFINET Device Number and
expansion of memory address fields from one word to two words. See COMMREQ
summary in Section 6.3.3.
3. Pulse Test and Assign Monitor COMMREQs do not support Genius bus address of 255 to
send messages to all blocks.
4. COMMREQ commands: GCG001 does not support all datagrams. See section 6.3.2 for a
corresponding list of supported COMMREQs.
5. GCG001 supports hot-standby and duplex redundancy modes only. No support for dual-
bus redundancy.
6. GCG001 can be assigned to bus addresses 30 and 31 only.
7. GCG001 does not support Field Control, GENI, GENA, or PCIM.
8. Prior to V2.0.0, GCG001 did not support 76.8K and 38.4K baud rates. Beginning with
V2.0.0, all Genius baud rates are supported.
9. Prior to V1.1.1, fault contact operation has changed. Whenever there is a fault on a single
channel of a Genius block, all fault contacts associated with that Genius block will
become active. All faults on that device must be cleared before any of the fault contacts
will de-energize. Beginning with V1.1.1, when there is a fault on a single channel, none of
the fault contacts will become active.
10. Genius faults routed through a GCG001 appear as PROFINET faults to the CPU. The same
fault routed through a Genius Bus Controller will present a different error code.
11. Prior to V1.1.1, when a Genius block encounters a circuit fault on one or more points or
channels, the GCG001 causes all of the input references associated with that block to
either hold last state or go to default values until such time as the fault is cleared. See the
Alarms discussion in section 4.1.4 for a work-around to this behavior. However, beginning
with V1.1.1, when a Genius block encounters a circuit fault on one or more points or
channels, the GCG will cause only the faulted input references to hold the last state or go
to default values. The other points or channels on the block will continue to operate
normally.
