4-2-2 Installing the USB Driver
The following restrictions apply to the connection of the CP1E to a computer due to the USB specifica-
tions. Keep these restrictions in mind when using the USB port.
• Only one CP1E CPU Unit can be connected by USB to a single personal computer. It is not possible
to connect multiple CP1E CPU Units simultaneously.
• Do not remove the USB cable while connected online. The application must be offline before the
cable is removed. The CX-Programmer will not go online simply by reinserting the USB cable. Place
the CX-Programmer offline before reinserting the USB cable, then place it online again.
The USB driver for CP1E must be installed on the computer running the CX-Programmer in order to
connect the CP1E to the computer via USB.
When the personal computer is connected to the CP1E by USB cable, the personal computer automat-
ically recognizes the device and the USB driver installation is started.
Connect the computer’s USB port (1) and the CP1E CPU Unit’s peripheral USB port (3) with a USB
cable (2).
The USB driver will be automatically installed when the cable is connected.
Additional Information
If the software is not automatically installed, refer to Installing a Specified USB Driver later in this
section.
