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:

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.
