Simple Writing of Values

Used when an external system must perform a simple writing or else send the value of a setpoint in a device, for example. Depending on the device, that writing must be performed on the same variable for status reading, or to a second variable created specifically for this purpose.

Single Variable for Reading and Writing

In this case, create a Bidirectional Link in the Value property of both Master and Slave Driver Tags. In addition, users must also configure the respective Master and Slave Driver Tags to allow reading and writing.

Exclusive Variable for Writing

In this case, create a Reverse Link in the Value property of Slave Driver Tags sending a value to the Master Driver.
