Power-Up

The GCG001 powers up whenever 24Vdc power is properly applied via the connector shown
in Figure 9. During the power-up sequence, the GCG001 module runs diagnostics and
initializes its hardware components. When the necessary hardware components have been
initialized and tested, the module transitions to either normal operation or, if the firmware
load pushbutton is being depressed (see Figure 8), to the firmware update mode.
The firmware update mode is described in Section 2.7.
As the GCG001 transitions to normal operation, it attempts to establish communications
with the PROFINET Controller. Until communications have been established, normal
operation cannot begin.
Once the PROFINET Controller matches the configured PROFINET Device Name that of the
GCG001, PROFINET communications will begin. Any faults detected by the GCG001 prior to
this event will then be uploaded to the PROFINET Controller.
Normal system operation will begin once the RX3i is in RUN mode, PROFINET
communications are up and running and Genius Bus operations are also up and running.

Problems during Power-up

Certain conditions can prevent the module from powering up and becoming operational or
entering firmware update mode:
Problem
Hardware failure
Invalid boot image
Invalid firmware

5.3.2 Transitioning from Firmware Update Mode to
Operational Mode
As described in Section 2.7, the firmware load pushbutton (see Figure 8) must be depressed
during power-up in order to invoke the GCG001 firmware load mode. Whenever the
GCG001 is powered up without this button being depressed, normal operating mode will
commence following power-up testing and initialization. Cycling power will transition the
module from one mode to the other, depending on the condition of the pushbutton.

Module Faults in the RX3i I/O Fault Tables

Module faults from the Genius Devices downstream from the GCG001 Genius Gateway are
passed to the PROFINET Controller and then to the PLC, where they are visible in the PLC's
I/O Fault Table. For details on the operation of the RX3i Fault Table, refer to the PACSystems
RX7i, RX3i and RSTi-EP CPU Reference Manual, GFK-2222 Chapter 14.
