PLC devices
You can specify PLC devices in the Variable Link entry area.
To pass data from PLC devices, specify the PLC devices in this area.
There are two methods to specify PLC devices.
1. Click the Device Tree button and select the devices on the Device Tree.
The devices that are displayed in the Device Tree are the devices that are used in WindLDR.
2. Directly enter devices in the Variable Link entry area. Refer to the following for the input format.
■ Device format
1. Bit device
The format to specify a bit device is as follows.
Format: "IDEC" ":" "Symbol" ":" "Address"
Example: To specify internal relay M0050 IDEC:M:M0050
2. Word device
The format to specify a word device is as follows.
When you specify a bit in a data register, specify the bit address after the data type “Bit”.
Format: "IDEC" ":" "Symbol" ":" "Address" "." "Data type"
Example: To specify data register D0050 as data type Word IDEC:D:D0050.Word
Example: To specify the 15th bit in the data register D0050 as data type Bit, IDEC:D:D0050.Bit15

Linking to WindLDR
You can link the system to the WindLDR simulation function when you have specified PLC devices in the Variable Link area.
Link to the WindLDR simulation function with the following procedure.
1. Click Simulation on the WindLDR ribbon menu to start the simulation.
2. Set the Web Page Editor operation mode to run mode.
When data is input from a PLC device
You can check the operation of the system by changing device values in the WindLDR Batch Monitor dialog.
When data is output to a PLC device
You can check device values in the WindLDR Batch Monitor dialog.
When 32-bit data storage setting is changed on Function Area Settings dialog box, the changed setting is applied to the web page editor once a project is saved and opened.
