7.5.1 Procedure - Changing the Device/PLC at Runtime (Indirect Device)

System Structure Example

Operation Example

In the Data Display, specify the address (D100) in the indirect device (Indirect1).

Change the device/PLC using a Selector List.

Setup Procedure

1. Set up device/PLCs for the system. See the following system structure for the setup. For the setup procedure, see the following.

2. Set up the indirect device/PLC. In the [System Settings], click [Device/PLC] and open the [Device/PLC 2] tab.
   

3. In the [Device-Specific Settings] area, on the right-side of the [PLC 2] settings, click the Add Indirect Device icon.
   The indirect device appears and the Device ID fields are added to [PLC2], [PLC3] and [PLC4].
   

   

   • You can change the [Indirect Device Name] and Device ID. Do not use the same [Device ID] on the same driver.

4. Set "LS0100" in the [Device ID Address] field.

5. In the [Initial ID] field, define the [Device ID] device/PLC to communicate with when the [Device ID Address] is set to "0" (for example, right after the display unit is turned ON). (Example: 1)

6. Open the [Device/PLC 3] tab. In the [Device-Specific Settings] area, on the right-side of the [PLC 6] settings, click the Add Indirect Device icon.
   The indirect device line appears and the [Device ID] fields are added to [PLC6], [PLC7] and [PLC8].
   

7. Set "LS0101" in the [Device ID Address] field.

8. Set the [Initial ID]. (Example: 1)

[Indirect1] and [Indirect2] are set as indirect devices. Click [Indirect Device Configuration] and check the structure.

Set up indirect devices in parts. (This example explains how to set the Indirect1.)

9. Open base screen 10 and draw a Data Display.
   Double-click the Data Display to open its dialog box

10. In the [Monitor Word Address] field, click the icon to display the [Input Address] dialog box. From the [Device/PLC] list select the indirect device "Indirect1". For the device address set "C00000". Click [Ent].
    

11. As required, define other settings such as the Data Type and Input Range and click [OK].

Next, configure settings to change the device.

12. On base screen 10 draw a Selector List.
    Double-click the Selector List to open its dialog box

13. Set the [Display Count] to 3.

14. Select [Word Operation] and set "LS0100" in the [Word Address] field.

15. In the [Word Action] drop-down list, select [Write Data]. Set the [Constant] to 1. In the [Item Name Setting] field, type "Unit 1".
    

16. In the [Selector Function List] click [Add] and select [Word Operation].

17. Set the [Constant] to 2 and in the [Item Name Setting] field type "Unit 2".

18. In the [Selector Function List] click [Add] and select [Word Operation].

19. Set the [Constant] to 3 and in the [Item Name Setting] field type "Unit 3".
    

20. As required, define other settings such as the Font or Switch settings and click [OK].
