Communication
11.1 Communication according to PROFIdrive
The telegram structure
● Parameter p0978 contains the drive objects that use a cyclic PZD exchange. All drive
objects after the first zero do not participate in the cyclic exchange.
● If the value 255 is written to p0978, this drive unit is visible to the PROFIBUS master and
empty (without the actual
process data exchange). This enables cyclic communication of a PROFIBUS master in
the following cases:
– with unchanged configuration to drive units that have a different number of drive
– with deactivated drive objects, without having to change the project
● One PZD = one word.
● Physical word and double word values are inserted in the telegram as referenced
variables.
● p200x apply as reference variables (telegram contents = 4000 hex or 4000 0000 hex in
the case of double words if the input variable has the value p200x).
