Review the following information for setting up and configuring the Roc800 Ethernet driver.

Manufacturing Connect Edge Compatible Series

Compatibility parameter	Compatible items
Driver type	Ethernet
Validated devices/series	Emerson ROC800

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

If the device is configured for Ethernet access, find its network parameters. Otherwise, use Emerson software V2.55 on your computer to configure the device for Ethernet access.

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

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

Parameter	Value
Type	Emerson
Driver	Roc800 Ethernet
Network Address	The device address you defined in Step 1
Network Port	4000
Operator ID	LOI
Device Address	240
Device Group	240
Host Address	239
Host Group	1

Step 3: Configure the List of Registers

When you Add Tags to the connected device, refer to the following register table and tag parameters. You can also Search for Pre-defined Device Tags for this device.

Refer to the following additional resources:

Register Table

Name	Value Types
OP	JSON, HEX
PT	JSON, HEX, AC3, AC7, AC10, AC12, AC20, AC30, AC40, INT8, INT16, INT32, UINT8, UINT16, UINT32, FL, DBL, TLP, TIME
History	JSON
Alarms	JSON
Events	JSON

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.

Opcode: Select the Opcode to use.

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 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).
