Siemens SIMATIC 6DL1 136-6AA00-0PH1 - HART Gate

The higher the smoothing is selected, the more stable the smoothed analog value is and the
longer it takes until the smoothed analog signal is applied after a unit jump.
Note
After start-up, short circuit, wire break or other channel fault, the smoothing is restarted.
If, for example, the smoothing is parameterized with 16 conversion cycles and all channels are
active, then, with a set interference frequency suppression of 50 Hz, it takes up to 2400 ms until
the process value is reported.
Up to the 󹪝rst valid process value, the peripheral module for the channel reports a value of 0 and
QI = 0.
The following 󹪝gure shows how many conversion cycles it takes for the smoothed analog value
to be completely available, depending on the con󹪝gured smoothing. This applies to every signal
change at the analog input.

5.4.8 HART gate
De󹪝nition
This parameter is used to enable the HART communication for the I/O module.
The "HART gate" parameter acts as a fail-safe "main switch" for the complete module.
