Communications via PROFIBUS PA: Pointek CLS200/300
Digital model
Notes:
• The following instructions assume that the user is familiar with PROFIBUS PA.
• For more detail, please see the full manual.
Pointek CLS200/300 is a Class B, Profile Version 3.0, PA device. It supports Class 1 Master for
cyclic data exchange, and Class 2 for acyclic services.
To configure Pointek CLS200/300 we recommend SIMATIC Process Device Manager (PDM) by
Siemens. (For more information go to > www.siemens.com/simatic-pdm.)
Device Description
To use PDM with PROFIBUS PA, you will need the Device Description (DD) for Pointek CLS200/
300. Go to > Device Catalog > Sensors/Level/Capacitive/Siemens Milltronics, or download it
from: www.siemens.com/level under Downloads on the Pointek CLS200/300 product page.
After downloading the DD file, you need to execute DeviceInstall.
Configuration
To configure a PROFIBUS Class 1 Master (for example, a PLC), you will need the GSD file,
SIEM80E9.GSD. It can be downloaded from the Pointek CLS200/300 product page at:
www.siemens.com/level, under Downloads.
Setting the PROFIBUS address
The factory setting for the PROFIBUS address is 126. Reset it locally using Mode 15 (see page 8),
or remotely via the bus, using a parameterization tool such as SIMATIC PDM or HW Config.
When cyclic data transfer with a Class 1 Master is in process, the address can only be
changed via the bus.
Bus Termination
Note: PROFIBUS PA line must be terminated at both extreme ends of the cable for it to work
properly. Please refer to the PROFIBUS PA User and Installation Guidelines (order number
2.092), available from www.profibus.com.
Transmission of user data via PROFIBUS PA
The user data is the OUT parameter of the discrete input function block and is composed of the
Logical Level and Status bytes.
