Validated devices/series | Devices that support the MTConnect standard |
To set up and configure this device in Litmus Edge, you will need to do the following:
- Step 1: Set up and Configure the PLC Device
- Step 2: Set up the PLC Device in Litmus Edge DeviceHub
- Step 3: Configure the List of Registers
Step 1: Set up and Configure the PLC Device
If the device is configured for Ethernet access, find its network parameters. Otherwise, use PLC software on your computer to configure your device for Ethernet access.
Step 2: Set up the PLC Device in Litmus Edge DeviceHub
Configure the following parameters when you Connect a Device with this driver. Update default values to the specific setup of your device.
Parameter | Value |
|---|---|
Type | MTConnect Ethernet |
Driver | MTConnect Ethernet (Gen1.3) |
Network Address | The device address you defined during Step 1 |
Port | 47808 |
Step 3: Configure the List of Registers
When you Add a Tag to the connected device, select the name R and value type raw, and then configure the remaining parameters.
You can also browse for tags to add to this device. See Browse Tags.
Tag Parameters
- Name: Select R.
- Value Type: Select raw.
- Polling Interval: Enter a value in seconds.
- Tag Name: Enter a name.
- Description (Optional): Enter a description for the tag.
- Tag Formula: Enter a formula for the tag to process the generated data. Two variables are permitted: value (current tag value) and timestamp (current tag UNIX time in milliseconds). The following math functions are available:
- sin
- cos
- sqrt
- tan
- power: power(x) performs the operation 10^x.
- log: log(x) is the natural logarithm (the logarithm is in base e).
- exp: exp(x) performs the operation e^x.
- Only Publish on Change of Value: Select the checkbox to customize NATS messages to be published only when the value parameter changes from a previous value to a new one. Change of Value only applies to boolean, numeric (such as int or float), and simple string data types. It does not apply to complex types, such as JSON or array. Poll-once topics will not be affected by Change of Value settings. These topics will still only see a single message.
- Meta Data: Metadata summarizes basic information about data. This feature allows you to define key-value pair data for the device output payload later on. It can then be used to find, use, and reuse particular instances of data.
Note: If you use special characters in meta data key names, the special characters are replaced with underscore characters in the payload. This can cause two key names to be combined into one. For example, configuring the key names a**b and a&&b will cause only one key name to be created (a__b).
