7.8.1.1 Change Device/PLC Settings Guide

Summary

Displays the settings of the currently specified devices/PLCs.

If you select the LT series model, the maker, the series, the ports are fixed as follows.

[LT Driver] is the same as [Memory Link].

Manufacturer

Displays the currently specified device/PLC maker.

Series

Displays the currently specified device/PLC series name.

Port

Displays the connection port of the currently specified device/PLC.

If the port is also used for other devices/PLCs, is displayed to the right of the [Port].

Text Data Mode

Displays the text data mode of the currently specified devices/PLCs.

Change

When the [Change Text Data Mode] dialog box is displayed, you can change the text data mode. Normally the text data mode is specified according to each device/PLC.

Data in Device Addresses

Select the data device storage order from [Store from Top Data] or [Store from Last Data].

Storing the text "ABCDE"

Store from Start Data

String Data Mode 1

Store from Last Data

String Data Mode 3

LH/HL Storage

Select the data storage order to specify in one word (16 bits) from [LH Order] or [HL Order].

Storing the text "ABCDE"

HL Order

String Data Mode 1

LH Order

String Data Mode 2

Double Word LH/HL Storage

Select the data storage order to specify in two words (32 bits) from [LH Order] or [HL Order].

Storing the text "ABCDE"

HL Order

String Data Mode 1

LH Order

String Data Mode 5

Text Data Mode

Displays the number associated with the Text Data Mode storage order.

Select

Select the text data mode to be used.

Communication Settings

Configure the settings according to the device/PLC. The settings differ depending on the series. See "GP-Pro EX Device Connection Manual." It is recommended to keep the default settings for [Timeout], [Retry], and [Wait to Send].

Device-Specific Settings

Set this according to each device/PLC.

Allowable Number of Devices/PLCs

Displays the number of connectable units according to the type of the display unit specified.

Add Device

Each time you click the [Add Device], one device/PLC is added.

You cannot add the PLC if the [Allowable Number of Devices/PLCs] or the maximum number of sockets is reached the limit or if the total of PLCs and indirect devices is set up to 128.

Increase Allowable Number of Devices/PLCs

When Yamatake Corporation MODBUS TCP Master is selected for the device/PLC, this selection appears. Click this button and the [Increase Allowable Number of Devices/PLCs] dialog box appears.

The number of connectable units can be expanded to 64 when the [Increase allowable number of Devices/PLCs] check box is selected.

Delete Device/PLC

Deletes the device/PLC settings.

Device Name

Set the name of a device/PLC characters from 20 to 10 (single-byte).

Do not duplicate the device name.
You cannot use a space and the following symbols.
+ - * / = % & ^ | \ : . , â€ # ? @ [ ] < >

Device/PLC Settings

Set individual settings as needed according to the device/PLC. Click the button to display the [Individual Device Settings] dialog box.

The [Individual Device Settings] differ depending on the PLC. For details on the settings of the device/PLC, see "GP-Pro EX Device Connection Manual."

Device ID

When using Indirect Device, and the series in the [Individual Device Settings] dialog box match the device/PLC, use this field to identify the device from 1 to 128.

Make sure you do not duplicate the Device ID with other indirect devices in the same driver. If the Device ID is duplicated, the warning icon appears beside the field.

Add Indirect Device

Set up the Indirect Device feature. Click this button to add a new indirect device to the list. You can add up to 64 indirect devices.

You can add up to a total 128 devices/PLCs and indirect devices to a single driver. However, the allowable number of devices/PLCs varies depending on the driver.

Indirect Device Name

Set the name of the indirect device with up to 20 single-byte characters (or 10 double-byte characters).

Do not duplicate device names.
The name cannot include a space or any of the following symbols.
+ - * / = % & ^ | \ : . , â€ # ? @ [ ] < >

Device ID Address

When using indirect devices, the value in the Device ID Address identifies the device ID of the device/PLC to communicate with. You can only use the internal device addresses (LS area/USRS area).

If the Device ID Address stores a device ID with no associated device/PLC, the parts set to the indirect device will not work.

Initial ID

Right after the display unit is turned ON and the value in the [Device ID Address] is 0, use this field to specify which device/PLC to use from 1 to 128.

Update Indirect Device Settings

Displays the [Update Indirect Device Settings] dialog box. If you change individual device settings after changing indirect devices, use this dialog box to update selected indirect devices with the new device/PLC settings.

Indirect Device Configuration

Displays the [Indirect Device Configuration] dialog box. Use this dialog box to check the association between indirect devices, devices/PLCs, and device IDs.
