ABB Totalflow DB2 Serial
Review the following information for setting up and configuring the ABB Totalflow DB2 Serial driver.
Note: This driver is experimental. Some features may not work as expected.
Litmus Edge Compatible Series
Compatibility parameter | Compatible items |

Driver type | Serial |
Validated devices/series |
The IRC5 Controller device is not compatible with this driver. As an alternative, you can connect through an OPC UA server.
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 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 the 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 | ABB |
Driver | ABB Totalflow DB2 Serial |
Communication Port | Enter the local serial connection file path. |
Baud Rate | Enter the serial communication baud rate parameter. Default value 9600 |
Station ID | Enter the station ID. Default value 1 |
Data Bits | Enter the serial communication data packet size. Default value 8 |
Stop Bits | Enter the serial communication stop bit for marking the end of each data transmission. Default value 1 |
Parity | Select the desired error-checking method for serial communication. Default set to None |
Step 3: Configure the List of Registers
When you Add a Tag to the connected device, see the following Register Table and Tag Parameters sections. You can also Browse and Add Tags from a Device for the device.
See the following additional resources if necessary:
Register Table
The register table addresses follow the format <application>.<array>.<register>. When entering the address in DeviceHub, add left-padding zeros and remove the period delimiters. Find the list of registers in the TotalFlow XSeries Remote Controller User's Manual.
Name | Value Types | Address Format | Min Address | Max Address |
|---|---|---|---|---|
BIT | bit | TTTFFFDDDD | 0 | 2552553647 |
W_BIT | bit | TTTFFFDDDDdd | 0 | 255255364715 |
BYTE | byte, sint | TTTFFFDDDD | 0 | 2552553647 |
WORD | word, int, dword, dint, float, double, lword, lint | TTTFFFDDDD | 0 | 2552553647 |
DWORD | dword, dint, float, double, lword, lint | TTTFFFDDDD | 0 | 2552553647 |
STRING | string | TTTFFFDDDD | 0 | 2552553647 |
DATEANDTIME | dateandtime | TTTFFFDDDD | 0 | 2552553647 |
Tag parameters
- Name: Select a register name from the drop-down list. Available options depend on the names in the register table.
- Value Type: Select a data type from the drop-down list. 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. The value must in the decimal format within the allowed min/max range. Omit the leading zeros. The device might use the decimal (D), hexadecimal (H), or octal (O) address format. See the Register Table at the bottom of the dialog box. 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:
- 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 publish NATS messages only when the value parameter changes to a new one value. 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 are not 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).
