(2) Connection type

Users can select a connection type in the

Type

drop-down list box. The connection types

supported by COMMGR are as follows.



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.
