This driver supports communication with MITSUBISHI MELSEC-A Series PLCs through the programming port (loader port).
Communication Setup: Xpanel
Create a new Device
| To create a new device, select ‘Tools’ → ’I/O Devices’ or click the  I/O Device Name: Give a device name. This name will be used in the tag database, accompanied by the ‘Station Name’. |
Select a device type | After selecting the ‘OK’ button in the previous step, the ‘Serial Communication Configuration’ dialog box will appear as shown in the following picture:  In this window, set the ‘Device Type’ to ‘MITSUBISHI MELSEC A Loader’ and configure the remaining serial communication parameters. Make sure the following parameters match those shown in the image above, as these values are required for this protocol to work correctly. Baud Rate: 9,600 Parity: Odd Data Bits: 8 Bits Stop Bits: 1 Bit Comm. Type: RS232 |
Create a station | Move to the ‘Station’ tab of the ‘Serial Communication Configuration’ dialog box. In this dialog box, connected PLC stations can be configured and registered to the XPanel.  Each station can be configured using the following parameters: Station Name: Give a name to the PLC. This name will be used in the database window, accompanied by the ‘Device Name’. Station Type: Choose the type of connected PLC CPU. One of three CPUs can be chosen (AnS, AnA, AnU). Network ID: N/A Station No: N/A 16-Bit Data Swap: N/A 32-Bit Data Swap: N/A String Data Swap: N/A Using Checksum: N/A Comm. Error Message Pop Up: When this item is checked, Xpanel displays a communication error message box for every Rx and Tx error. Otherwise (unchecked), Xpanel does not display a message for communication errors. This message box will close automatically after a few seconds. |
icon in the toolbar. The following picture shows the first step in creating a new device:Address Notation
Device tag addresses used within Xpanel should have the following format:
Notation (Base) | Format | Example |
10 (decimal) | [Symbol][Address in decimal format] | D0012 |
16 (hexadecimal) | [Symbol][Address in hexadecimal format] | X01FC |
The following table lists the devices which can be referenced within the Xpanel database:
