Restrictions when
Connecting by USB
In conformity with USB specifications, the following restrictions apply when
connecting a computer running Support Software.
• A USB connection is possible for only one CP-series PLC from a single
computer. It is not possible to connect multiple PLCs simultaneously.
• Do not disconnect the USB cable while the Support Software is con-
nected online. Before disconnecting the USB cable, be sure to place the
application in offline status. If the USB cable is disconnected while online,
the situations described below will occur as a result of OS error.
• Windows Me, 2000, or XP:
The Support Software cannot be returned to online status by simply re-
connecting the USB cable. First return the Support Software to offline
status, and then reconnect the USB cable. Then perform the online
connection procedure for the Support Software.
• Windows 98:
If the USB cable is disconnected while online, an error message may
be displayed on a blue screen. If that occurs, it will be necessary to re-
boot the computer.
The peripheral USB port (conforming to USB 1.1, B connector) is a dedicated
port for connecting Support Software, such as the CX-Programmer.
