Process Data - CARLO GAVAZZI PD30ETB BP IO Serie Manual De Instrucciones

Access to internal parameters allows the user to see how the sensor is performing, for example by reading the
internal temperature.
Event Data allows the user to get diagnostic information such as an error, an alarm, a warning or a communication
problem.
There are two different communication types between the sensor and the master and they are independent of
each other:
• Cyclical for process data and value status – this data is exchanged cyclically.
• Acyclical for parameter configuration, identification data, diagnostic information and events
(e.g. error messages or warnings) – this data can be exchanged on request.

2.3.3. Process data

By default the process data shows the following parameters as active: 16 bit Analogue value, Switching
Output1 (SO1) and Switching Output 2 (SO2).
The following parameters are set as Inactive: SSC1, SSC2, TA, SC, DA1, DA2, AFO1.
However by changing the Process Data Configuration parameter, the user can decide to also enable the status
of the inactive parameters. This way several states can be observed in the sensor at the same time.
Process data can be configured. See 2.5.3. Process data configuration.
