$images\ico_intf.gif$ Types of interfaces

Two main types of interfaces

A driver can use one of the two main interface types:

Serial connection (COM port, modem or other scheduled connection)
Driver-specific interface (proprietary interface card or standard network card)

$images\ico_com.gif$ COM port connection

If the PLC and the PC are directly connected with a serial cable, select this option on the Connection Type tab and configure the COM port on the Serial Port tab.

$images\ico_modem.gif$ Modem connection

If the PLC and the PC are connected via a modem, select this option on the Connection Type tab and configure the modem, as required.

Remember to set the special parameters for remote connections on the Remote tab.

$images\ico_radio.gif$ Other scheduled connection connection

If the PLC and the PC are connected via another type of scheduled connection, select this option on the Connection Type tab.

Configure the COM port on the Serial Port tab and remember to set the special parameters for remote connections on the Remote tab.

Device-specific interface

Some drivers do not support any of the above serial connections, but only connections via device-specific interface cards or standard network cards.

When you add such a driver, this icon $images\ico_device.gif$ appears in the tree view. Dependent on the interface, one or more property sheets are shown.

Refer to the manufacturer’s documentation for further information.
