This section does not do any configuration, but is extremely useful for testing a configuration once a Modbus device is connected. The middle part, Find Target Device, is also essential for establishing a connection so that you can configure the device.

Diagnostic Read/Write

Object: Enter an object number or scroll to an object number 1 through 100. These translate into AI 1-40, AO 1-8, BO 1-8, and MI 1-60. The abbreviated object name is shown below the object number. This object number is used for reading and writing the Present Value, for setting In/Out of Service status, and reading Reliability.

Present Value: Enter a value to be written to a writeable object, or simply observe the value returned by reading an object.

Priority: AI/MI values do not require a priority to write (if writeable). AO/BO values do require a priority level unless the object is out of service. Select the priority level to be used in writing the object.

Read: Click this button to read the Present Value.

Write: Click this button to write the Present Value, using the selected priority level if applicable.

Relinquish: Check this box, then click the Write button, to relinquish a previously written priority level.
