2.4 Module Installation
2.4.1 Install SD Card
The SD card slot is designed to support a Secure Digital (SD) non-volatile memory card in
standard capacity format. This optional card has two distinct uses: (1) backup storage of some
key PROFINET configuration data and (2) loading new GCG001 module firmware. Insert the SD
Card into its slot at the rear of the GCG001 before mounting the module, as shown in Figure 8.
When shipped from the factory, the SD card will have been pre-installed. It will have been
programmed with the then-current version of the firmware for the GCG001. In the event the
firmware on the SD card needs to be updated, see section 2.7. Note that the firmware
upgrade should be performed before mounting the module.
2.4.2 Mounting the GCG001
The GCG001 is designed to mounted in one of the following ways:
a. In the expansion slot of an RX3i Universal Backplane
b. Panel-mounted
In both cases, at least 75 mm (3 in.) must remain clear above and below the module to allow
for convection cooling. See section 1.5.1 for mounting details.
Once the module has been mounted, connect 24Vdc power via the connector on the
underside of the module, connect PROFINET via the RJ-45 connectors and the Genius bus via
twisted pair cable. Each connection is described in the following section.
Once all connections are in place, it will be necessary to configure PROFINET. This is also
discussed in the following sections.
Power Connection
The module requires a user-supplied
24Vdc (±10%) power source wired to the
removable screw-terminal block located
on the bottom of the module. Connector
pin-outs are identified on the module, as
indicated at right. The module draws
0.2 A maximum current.
