  • Page 21: Cyclic Configuration

    The FI303 has 3 functional blocks with analog output (AOs) that the class 1 master uses to execute the cyclic services and the user must choose what configuration best suits their application. If the slave AO master is in AUTO, it will receive the value and the status of the class 1 master setpoint.
  • Page 22 The watchdog condition may be activated, prompting the equipment to enter a fail-safe mode when detecting a communication loss between the slave and the master equipment. Since the FI303 will be on a final element, it is recommended that a fail-safe value be configured.

For this procedure the following parameters are necessary:...
  • Page 24 The characterization curve is used to give a determined profile to the output. This is useful, for example, when the FI303 is controlling a valve with a non-linear characteristic. Characterization curve, when used, is applied to the input signal, before it is converted by the transducer to analog current.
