Communication PROFIBUS DP/PROFINET IO 10.1 Communications according to PROFIdrive

Note

Please refer to the following documentation for a detailed description of acyclic communication:

Reference: /P5/ PROFIdrive Profile Drive Technology Addressing:

PROFIBUS DP, the addressing can either take the form of the logical address or the diagnostics address.

PROFINET IO, addressing is only undertaken using a diagnostics address which is assigned to a module as of socket 1. Parameters cannot be accessed via socket 0.

Characteristics of the parameter channel

One 16-bit address each for parameter number and subindex.

Concurrent access by several PROFIBUS masters (master class 2) or PROFINET IO- Supervisor (e.g. commissioning tool).

Transfer of different parameters in one access (multiple parameter request).

Transfer of complete arrays or part of an array possible.

Only one parameter request is processed at a time (no pipelining).

A parameter request/response must fit into a data set (max. 240 bytes).

The task or response header are user data.
