Location: Click the Action menu on the Asset Configuration page and select Data Sources. Modbus TCP properties are available only after you add a Modbus TCP data source.

The Modbus TCP data source supports the following properties that you configure to affect how the device communicates with the Modbus slave.

Property Name Description
IP Address The TCP/IP address of the Modbus slave with which you want to communicate.
Port The TCP port of the Modbus slave with which you want to communicate. The default is 502.
Interval (sec) How often the InsightCM device process reads the Modbus slave device, in seconds.
Read Timeout (sec) How long the read process waits for a response from the Modbus slave device when initializing or reading from the device. If the Modbus slave device does not respond within the specified timeout, the InsightCM device attempts to re-open a connection after 30 seconds.
