Installing the USB Port Driver
The USB Ports on CPUs which support the embedded PROFINET function operate independently of the
PROFINET Controller function itself. Refer to the documentation for the related CPU.
For the slot-mounted PNC001 (-Ax module only), set
up use of the module’s USB port in either of these ways:
1.
Run the provided driver-
install application before connecting the computer’s USB port to the USB port
on
the PNC001 module for the first time.
2.
With the provided installation files accessible on either a local or network drive, attach the PC USB port to
the Rx3i IO LAN USB port.
a)
Windows opens a New Hardware Found Wizard dialog. Within the wizard application, enter the
location of the provided installation files.
b)
Windows then installs the USB driver compatible with the USB port.
The computer automatically assigns a serial port name for the USB port on the PNC001 module. A unique serial
port number will be used for each PNC001 module. The serial port name is COM followed by the next available
number from 1 to 256. After the computer assigns the module’s USB port a C
OM port name, it uses the same
name each time it connects to the module (except for a special case described below).
If the computer has already assigned all its available port names (COM1 through COM256), the next device to
attach is assigned a previously-used COM Port name:
1.
If the last assigned COM port name was COM256, the next COM port name assigned is the first
unconnected
COM port after the physical serial communications ports.
2.
If the last assigned COM port name was not COM256, the next COM port name assigned is the first
unconnected COM port in sequence.
After the initial installation process, the same computer can be attached to other RX3i PNC001 modules
without additional installation steps. The virtual serial port name is automatically assigned when the device is
attached to the computer.
Serial port settings must be 115200 baud, 8-None-1, with no flow control.
