SINAMICS G120 (CU240S DP) Control via PROFIBUS

V1.0, Beitrags-ID: 45288241

7.1.1.1 Standard Telegram

Various pre-assigned telegrams and a freely parameterized telegram are available

for this communication; these can be selected from the hardware catalog.

The freely parameterizable telegram (Universal module) can be used in this

function example. This has the advantage that the telegram structure can be freely

adapted to the particular application.

Analog to HW-Config, this telegram selection must also be made in the SINAMICS

G120 (refer to Chapter 6.5).

(1.) To parameterize the telegram, first select an Out-input range for I/O Type.

(2. and 3.) Then, when using the Universal module, the telegram length must be

defined for the send and receive directions. In this example, a length of 6 Words is

parameterized for sending (Output) and 6 Words for receiving (Input) - from the

starting address 256.
