Network Address	The device address you defined in Step 1
Port	5001

Step 3: Configure the List of Registers

When you Add Tags to the connected device, refer to the following register table and tag parameters.

Register Table

Name	Value Type	Address Format	Min Address	Max Address	Description
X	bit	DDD	0	255	Input Relay
Y	bit	DDD	0	255	Output Relay
M	bit	DDDD	0	7999	Internal Relay
T	bit	DDD	0	511	Timer Contacts
C	bit	DDD	0	255	Counter Contacts
SM	bit	DDDD	8000	8511	Source Int. Relays
S	bit	DDDD	0	4095	Step Relays
R	word	DDDDD	0	32767	File Register
SD	word	DDDD	8000	8511	Service Data Register
CV2	word	DDD	200	255	Counter Value
D	word	DDDD	0	7999	Data Registers
CV	word	DDD	0	199	Counter Value
TV	word	DDD	0	511	Timer Value

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. 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.

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 only publish NATS messages when the value parameter changes to a new 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 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. Metadata 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).
