Chapter 2 Starting and Setting
‣ RS232
A computer communicates with a PLC through a communication port on the computer.
‣ USB (Virtual COM)
A computer can connect to a PLC equipped with a USB port through a USB cable. However,
users have to make sure that a USB driver is installed on a computer before the computer
connects to a PLC equipped with a USB port. Please refer to appendix A for more information
about installing a USB driver.
‣ Ethernet
A computer communicates with a PLC through an Ethernet port on the computer.
‣ DirectLink (USB) & DirectLink (Ethernet)
They are the connection functions provided by Delta human-machine interfaces (HMI). If a
PLC connects to a HMI normally, a computer can connect to the HMI through a USB cable or
Ethernet, and connect to the PLC indirectly. Please refer to manuals for Delta
human-machine interfaces for more information about setting a connection.
‣ DVP Simulator & AH Simulator
This type of driver functions as a virtual channel connecting a simulator. If users specify this
type of driver in ISPSoft, COMMGR will transmit data between ISPSoft and a simulator once
related connection operation is performed. It is as if COMMGR connected to a real PLC.
(This mode is a framework adopted by ISPSoft version 2.00 and above.)
(3) Communication parameters
Communication parameters are set according to a connection type selected. Different
connection types have different communication parameters. The setting of parameters for the
different connection types is described in the following sections.
2.4.3.1 Setting Communication Parameters for RS232
(1) Users can type a driver name in the Driver Name box. Special marks can not be used except _.
(2) Select RS232 in the Type drop-down list box in the Connection Setup section.
(3) Select a RS232 communication port in the COM Port drop-down list box. Each item in the COM
Port drop-down list box is composed of a device name and a communication port number. The
communication ports in the COM Port drop-down list box are the same as the communication
ports in the Device Manager window.
