To set up and configure this device in Manufacturing Connect 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 Manufacturing Connect Edge DeviceHub

Step 3: Configure the List of Registers

Step 1: Set up and Configure the PLC Device

Verify the serial port connection between the Manufacturing Connect Edge device and the Omron PLC.

Identify the serial communication port (for example, /dev/ttyS0, /dev/ttyS1).

Record the PLC's serial communication parameters:

Baud Rate

Data Bits

Stop Bits

Parity

Note the PLC's Destination Node ID (Station ID).

Step 2: Set up the PLC Device in Manufacturing Connect Edge DeviceHub

Configure the following parameters when you Connect a DeviceConnect a Device with this driver. Update default values to the specific setup of your device.

Parameter	Value
Type	Omron
Driver	Omron Hostlink
Communication port	The serial port file path (for example, /dev/ttyS0, /dev/ttyS1)
Baud Rate	9600
Data Bits	7
Stop Bits	2
Parity	Even
Destination Node ID	0

Step 3: Configure the List of Registers

Tag Parameters

Name: Select a register name from the drop-down list. The available options depend on the names in the register table.

Value Type: Select a data type from the drop-down list. The available options depend on the register name selected.

Polling Interval: Enter a value in seconds. This determines how often the tag should poll the register for data.

Tag Name: Enter a name for the tag.

Description (Optional): Enter a description for the tag.

Address: Enter a tag address in decimal format, within the allowed min/max range. Omit the leading zeros. For Bit tags, append the bit address without the bit separator. The lowercase letters in the address format indicate how many digits you should enter in the Bit address.

Count: Enter the number of register values to read. A count higher than 1 will generate an array of values from the address value configured and respective subsequent address values.

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:

sqrt

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 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).
