For Live data, Historical data, Datalogging to MQTT broker, and Alarming you'll need to set up a data source and add variables. This article shows you how to do this for communication via Mitsubishi's MELSEC.

Prepare the machine

The machine needs to be prepared to enable communication.

Add a data source

The machine will need to be added as a MELSEC data source.

1. Go to Fleet Manager > Devices and click on your device name.
2. In the left menu, at Services, click on the icon and select Data source > MELSEC.
3. Enter the requested information (details below) and click on Add.

   Field	Description
   Name	Enter a name for the data source.
   Identifier	The identifier is entered automatically and ensures that every data source remains unique, even if they share the same name.
   IP address	Enter the IP address of your machine.
   Port	Enter the Port No. that you configured in your machine. In GX Works 2 this is called Host Station Port Number.
   MELSEC Serie	The Mitsubishi MELSEC series to which your machine belongs. If you're unsure, please consult the Mitsubishi website. "QnUCPU" is Mitsubishi's notation for every MELSEC-Q Series machine with CPU type Q..U..CPU, for example Q04UDVCPU or Q26UDEHCPU.
   Transport protocol	Select the same protocol that you configured in your machine (TCP/UDP).
   Network No. and PC No.	If configured in the machine, enter the correct settings here. If not, leave the default settings. Applicable when using a custom MELSEC machine network.
   Request destination module I/O No. and Request destination module station No.	If configured in the machine, enter the correct settings here. If not, leave the default settings. Applicable when using a specific I/O module for communication.
   Authentication type	The Ethernet connection in the machine may be password protected. Enter the password or leave it empty if no password is configured on the machine.
   Polling sleep time	The IXrouter will continuously request data from the machine. This then enables you to log aggregated values, like the average value or the maximum value that occurred, and to trigger alarms when certain conditions are met. The polling sleep time is the time that the IXrouter waits before asking data again, after it just received data from the machine. A polling sleep time of 100ms is recommended. In the rare case that you are experiencing a high CPU load on the machine, you can increase this setting to reduce the load.

Add variables

Once you've added a data source, you can start adding variables.

4. Under your Data source, go to Variables and click onAdd variable.
5. Enter the requested information (details below) and click on Add.

   Field	Description
   Name	Enter a name for the variable.
   Identifier	The identifier is entered automatically and ensures that every variable remains unique, even if they share the same name.
   Type	Select the variable's data type (bool, int, float, etc).
   Device type	Select the variable's device type (register type).
   Device No.	Enter the variable's address. The address notation (decimal or hexadecimal) depends on the selected device type. Device type Device No. notation SM - Special relay Decimal SD - Special register Decimal X - Input Hexadecimal Y - Output Hexadecimal M - Internal relay Decimal L - Latch relay Decimal F - Annunciator Decimal V - Edge relay Decimal B - Link relay Hexadecimal D - Data register Decimal W - Link register Hexadecimal TS - Timer (Contact) Decimal TC - Time (Coil) Decimal TN - Timer (Current Value) Decimal TS - Retentive timer (Contact) Decimal TC - Retentive timer (Coil) Decimal SN - Retentivetimer (Current Value) Decimal CS - Counter (Contact) Decimal CC - Counter (Coil) Decimal CN - Counter (Current Value) Decimal SB - Link special relay Hexadecimal SW - Link special register Hexadecimal DX - Direct access input Hexadecimal DY - Direct access output Hexadecimal Z - Index register Decimal R - Block switching method Decimal ZR - Serial number access method Hexadecimal
   Factor	Multiplies the value. Leave empty if the data type is boolean.
   Unit	Displayed behind the value (e.g. kg).

6. Repeat step 5 for every variable you want to add or click Import from CSV-file near the top right corner to add variables in bulk instead.
   
   • The structure of the CSV file is explained here: Import variables: CSV file structure.
   • Using Export to CSV-file and Import from CSV-file enables you to easily copy variables from one device to another device. Alternatively, you can also use device templates.

You have now made the changes in the IXON Cloud, but these are not yet active in your device. You will need to push your changes to your device for them to take effect.

7. Click on Push config to device in the top right corner.

Test variables

The variables test is recommended to check if all added variables are configured correctly. It shows the value of all variables if everything is configured correctly and shows an error if something is not configured correctly.

8. Click on Run test near the top right corner.
   • The test will attempt to update values every 0.5 seconds.
   • Is the test showing unexpected values? Check the addresses and data types of the variables.
   • Is the test showing a timeout error? Check that the data source is configured correctly and the machine is connected and powered on. If you are still getting a timeout error, contact your IT to make sure the test is not blocked. The test sets up an outgoing connection from your computer to the IXrouter using:
     

     Port	Transport protocol	Application protocol
     443	TCP	WebSocket
