PxG55x works according to the Profibus DPV1 specification and can be addressed
in cyclic or acyclic data traffic (
→ [5]).
Acyclic data traffic should be used to make device or process specific settings such
as definition of the Safe Values, Safe States etc. or for reading or writing of rarely
used attributes.
Cyclic data traffic is used for continuous exchange of the required process para-
meter values, i.e. pressure value and status indications. A number of standard
telegrams are available for cyclic data traffic. They can be selected according to
requirements (
→ section "Cyclic Message Telegrams").
