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

Refer to the following additional resources:

Register Table

Name	Value Type	Address Format	Min Address	Max Address	Description
X	bit	Ddd	1	816	Input Status (Read Only)
Y	bit	Ddd	1	816	Output Status

T	bit	DDDDD	1	500	Timer Status
CT	bit	DDDD	1	250	Counter Status
SC	bit	DDD	1	1000	System Control Bit
DS	word	DDDD	1	4500	Data Registers

DH	word	DDD	1	500	Data Registers
DF	word	DDD	1	500	Data Registers (Double Word)
XD	word	D	0	8	Input Status Registers
YD	word	D	0	8	Output Status Registers
TD	word	DDD	1	500	Timer Current Values
CTD	word	DDD	1	250	Counter Current Values
SD	word	DDDD	1	1000	System Data Registers
TXT	word	DDDD	1	1000	Text Data 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. 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).
