Ethernet (local) communication settings

The dialog is only available via “Server” > “Communication Settings” when you have set the parameter “Enable MEWTOCOL OPC Server comatibility namespace” to TRUE under “Tools” > “Options” in the “Client Interaction Settings” pane.

NOTE

You can only change the communication parameters for the OPC Server if the OPC subsystem has not been started.

Set the communication parameters according to your hardware. This connection is based on TCP/IP protocol.

Read the "ET-LAN SYSTEM Technical Manual" when you are using the ET-LAN unit.

If you select “Ethernet (local)” as the network type, the following options are available. Note that the bottom half of the dialog looks different depending on whether you have activated the option “Use link station No.” or not.

Parameter		Description
“Computer”	“Automatically acquire IP address”	Activated by default. If not displayed, set properties of TCP/IP from network setting in control panel. (The setting procedure differs depending on the operating system used. Please refer to the manuals and help of the operating system.)
	“IP address”	Specify the IP address of destination (PLC) to communicate with if the option “Automatically acquire IP address” is deactivated.
	“Port number”	Specify a value between 1025 and 32767 in decimal format (default: 1025). The port number for the IP address must be a unique, i.e. it cannot be used twice on your computer.
	“Station No.”	Specify a value between 1 and 64 in decimal format (default: 64). The station number must be different from the destination station number (PLC) that follows. (If no ET-LAN unit is used, the setting under “Station No.” is ignored.)
“Communication timeout”		Specify a value between 1 and 950 seconds (default: 15).
“Connection timeout”		Specify a value between 1 and 180 seconds (default: 60).

If “Use link station No.” is deactivated (default setting), use the command buttons “Add” or “Change” to open the dialog “Register destination”. Here you can add new or change existing destinations.

Parameter		Description
“Use ET-LAN unit”		Activate the option when you are using the ET-LAN unit. Do not activate the option when using the Ethernet-RS232C converter, etc., for example.
“Station No.”		Specify a value between 1 and 64 in decimal format (default: 1). The destination station number must be different from the station number entered under “Computer”. (If no ET-LAN unit is used, the setting under “Station No.” is ignored.)
“IP address”		Specify the IP address of the destination (PLC) to communicate with.
“Port number”		Specify a value between 1 and 32767 in decimal format (default: 1025) that is different from the port number shown next to “Computer port no.”.
“Computer port no.”		Read-only field displaying the port number you have entered in the previous dialog for information.

When the option “Use link station No.” is activated, only one destination can be entered.

Parameter		Description
“Destination”	“Use ET-LAN unit”	Activate the option when you are using the ET-LAN unit. Do not activate the option when using the Ethernet-RS232C converter, etc., for example.
	“IP address”	Specify the IP address of the destination (PLC) to communicate with.
	“Port number”	Specify a value between 1 and 32767 in decimal format (default: 1025) that is different from the port number entered under “Computer”.
	“Station No.”	Specify a value between 1 and 64 in decimal format (default: 1). The destination station number must be different from the station number entered under “Computer”. (If no ET-LAN unit is used, the setting under “Station No.” is ignored.)

The following command buttons are available:

“OK”	Use this command button to save the communication settings. However, the current settings are not entered in the list of registrations. If you want to enter them to the list, use “Add registration” before selecting “OK”.
“Initialize”	Use this command button to reset the current parametersettings to the default values.
