4.5 Programming
4.5.1 Introduction
Cyclic and acyclic data as well as diagnostic data can be transferred via the
PROFINET communication system. The number of cyclic data is variable and
is defined with the aid of profiles.
The cyclic and acyclic data have been designed in such a way as to match the
following profiles and meet the following standards:
•
Standard Telegram 1 = “PROFIdrive”
•
Vendor specific 1000 = “PDShort”
•
Vendor specific 999 = “Transparent Mode”
The appropriate profile can be selected by the user in the PLC.
Below is a brief description of the individual profiles.
Acyclic communication
Standard Telegram 1 = “PROFIdrive”
The profile corresponds to the standardized PROFIdrive profile version 4.2.
This group supplements the variable frequency drive profiles with the PROFI-
drive profile, as defined by the PROFIBUS Nutzerorganisation e.V. (PNO) for
cyclic data exchange with a drive. Control and status data will be processed
as per the PROFIdrive profile.
The Standard Telegram 1 communication profile can be used to exchange
control commands (e.g.: control word, status word, setpoint and actual
values).
Vendor specific 1000 = “PDShort”
Control and status data are processed as per the profile defined by the manu-
facturer (Eaton).
The profile corresponds to the standardized PROFIdrive profile version 4.2
with the difference that 2x16 bits of additional data are supplied in cyclic
communication and the PROFIdrive mechanism for the control and status
words is processed internally. This means the user does not have to carry
out the process. The control word and status word are processed internally
according to the PROFIdrive profile.
Vendor specific 999 = “Transparent Mode”
This is an Eaton-specific profile (manufacturer-specific telegram).
The internal communication is converted to PROFINET IO data.
Control and status data are processed as per the profile defined by the
manufacturer (Eaton)
