Configuration of PA-Devices
From Control Builder M point of view PROFIBUS PA-devices are seen like
PROFIBUS DP-devices. Every PA-device needs to have a hardware definition file to
get it configured on PROFIBUS. But additional configuration aspects have to be
taken into account to get a proper engineering.
Connecting PA-Devices via Linking Device LD 800P and SK3
Due to the fact that PA is using a different transmission technology than DP, PAdevices cannot be connected directly to PROFIBUS DP. A linking device has to be
used.
The Linking Device LD 800P and SK3 is the interface between PROFIBUS DP and
PROFIBUS PA. The LD 800P and SK3 is a transparent gateway. PA devices are
seen as DP devices on the PROFIBUS DP. The LD 800P and SK3 supports all
defined baudrates for PROFIBUS DP from 9.6 kbit/s up to 12 Mbit/s.
The GSD file for PA devices normally do not support higher baudrates. At a
maximum 93.75 kbit/s are entered that is used by SK1. To get the PA devices
running in AC 800M also with higher baudrates, you have two alternatives:
1. Make GSD import with Device Import Wizard
If the parameter Slave_Family is set to 12 in the GSD file, a PA device is
defined. The Device Import Wizard checks this parameter and enters
automatically the settings for the higher baudrates in the HWD files for these
devices. For more information about Device Import Wizard see Insert a new
Slave Type on page 57.
2. Use Device Type Object delivered with Device Library
Device Type Objects delivered with the Device Library always have the higher
baudrates enabled to be used with LD 800P and SK3. For more information
about Device Type Objects see Device Management PROFIBUS & HART on
page 62.
