Acyclic Services - Beckhoff EL3182 Documentation

HART
The values are automatically updated every three seconds. This value is independent of the set polling time.
Cyclic process data
Furthermore, HART Cmd 3 can be mapped cyclically (see CoE object index 0x6080 [} 88] for channel 1 or
index 0x6090 for channel 2). A HART-specific set of additional process data, which can be read by the
control system, can be created by ticking the "Cyclic Process Data" checkbox.

Once the configuration has been activated, it is updated cyclically with the polling time used as time base.
The acyclic service from this dialog takes values from the cyclic buffer every three seconds.
