This driver is used to connect a CIMON Xpanel with a KOYO DL06 PLC using RS-232C or RS-422/485.

Communication Setup: Xpanel

Create a new device

To create a new device, select [Tools] → [I/O Devices] in the menu or click the icon in the main toolbar. The ‘I/O Device Configuration’ dialog box will appear as shown below:

I/O Device Name: Give a device name. This name will be used in the tag database, accompanied by the ‘Station Name’.

Select a network 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 ‘KOYO DirectNet’ and configure the remaining serial communication parameters. Ensure that these parameters are matched with the device’s configuration. See the Communication Configuration section for more information.

Create a station

Move to the [Station] tab of the ‘Serial Communication Configuration’ dialog box and click ‘Add Station’. The ‘Station’ dialog box will appear as shown below:

Each field can be configured with the following rules:

Station Name: Give a name to the PLC. This name will be used in the tag database, accompanied by the ‘Device Name’.

Station Type: Choose either 'DirectNet(HEX)’ or ‘DirectNet(ASCII)’, depending on the PLC configuration.

Station No: Specify a decimal number between 1 and 247. This must match the station number of the PLC.

See the Communication Configuration section for more information about the remaining parameters.

The above table is based on documentation for the Koyo DL06.

If the model used is not a Koyo DL06, DL405, or DL205, then you can only use word memory (you cannot access individual bits).

Digital Tags

  • Example of word memory referencing:

    • V40000.15 - bit 15 of word 40000

    • V40000.0 - bit 0 of word 40000

  • Example of discrete memory referencing:

    • GX017 - bit 17 in octal (15 in decimal) of the remote I/O
