7.2 Procedure for SIEMENS SIMATIC S7 and STEP 7
Different configuration software is used for different PROFIBUS masters. How
this works with the SIMATIC Manager for the SIMATIC S7 in version 5.1 will be
explained with an example. At least version 5.1 SP4 of STEP 7 is required for use
of DPV1 with STEP 7. The SIMATIC S7 CPUs must also support DPV1. For
whether the particular CPU supports DPV1, see the CPU characteristics under
the hardware manager.
7.2.1 The HW-config
To link in the GSD file in the STEP 7, open the menu "Extras" "Neue GSD Datei
einbinden." Then display the GSD in the device catalog under "Extras" "Katalog
Aktualisieren." This must done only once. After this, the inverter appears at the
position as shown on the screen (Fig. 7-1) in the hardware catalog. HW-Config in
STEP 7 may look like this.
Fig. 7-1: HW-Config
It is not necessary to reserve a separate memory area for the acyclic services
(DPV1). This means that no PPO type must be selected which supports PKW.
Every PPO type has this capability with the DPV1 protocol.
