To monitor the data points of a TCP device or entity, you must add them to the device or entity in Security Center.

Before you begin

What you should know

The Industrial IoT plugin role acts as the TCP server. It must be configured to identify data and events by evaluating the payload sent by the devices against regular expressions.
NOTE: To capture a value with a regular expression, a capture group (delimited by parentheses) must be present. The plugin role uses the value returned by the first capture group. If there is no capture group in the regular expression, no value is returned. For help with regular expression syntax, see the Regular Expression Cheat Sheet.

Procedure

  1. From the Config Tool home page, open the Plugins task.
  2. Select an TCP device or entity.
  3. In the Data points section, click Add a data point ()
    The Add a data point dialog box opens.

  4. Enter the following information:
    Name
    The name of the data point.
    Regular expression
