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.

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.
