A.3 Setting the USB Port on a DVP-SX2 Series PLC

The operation of the USB port on a DVP-SX2 series PLC differs from the operation of the USB ports

on other models in that a circuit which converts USB to RS-232 is installed in the DVP-SX2 series

PLC. As a result, the operation inside the DVP-SX2 series PLC adopts RS-232 although the port on

the PLC is a USB port. Users must select

RS232

in the

Type

drop-down list box in the

Driver

Properties

window if they want to create a driver in COMMGR. The setting of the communication

protocol for exchanging data through the USB port is the same as the setting of the communication

protocol for exchanging data through a general RS-232 port.

Users can set the communication protocol for exchanging data through the USB port on a DVP-SX2

PLC by means of writing a value into D1109. Please refer to the programming manual for DVP-SX2

series PLCs for more information. If users want to create the driver in COMMGR, they have to make

sure that the communication protocol for exchanging data through the driver is the same as the

communication protocol for exchanging data through the USB port on a DVP-SX2.
