Communication PROFIBUS DP/PROFINET IO
10.1 Communication according to PROFIdrive
Telegram interconnections
● When you change p0922 = 999 (factory setting) to p0922 ≠ 999, the telegrams are
● Exceptions here are telegrams 20, 111, 220, and 352. Here, selected PZDs can be
● When you change p0922 ≠ 999 to p0922 = 999, the previous telegram interconnection is
● If p0922 = 999, a telegram can be selected in p2079. A telegram interconnection is
This is an easy way to create extended telegram interconnections on the basis of existing
telegrams.
The telegram structure
● The parameter p0978 contains the sequence of DOs that use a cyclic PZD exchange. A
● If the value 255 is written to p0978, the drive unit emulates an empty drive object that is
● The following must apply to ensure conformity with the PROFIdrive profile:
● One PZD = one word.
● Only one of the interconnection parameters (p2051 or p2061) can have the value ≠ 0 for
● Physical word and double word values are inserted in the telegram as referenced
