6.3 Commissioning the PROFIBUS
®
PA interface
!
Note!
Chapter 11 "Operation using PROFIBUS
®
PA" provides a detailed description on all of the functions
required for commissioning.
6.3.1 Commissioning PROFIBUS
®
PA
Procedure:
1. Check hardware write protection
The WRITE PROTECTION parameter shows whether write access to the device is possible
using PROFIBUS
®
(acyclical data transfer, e.g. using "FieldCare" operating program): SETUP
ADVANCED SETUP WRITE PROTECTION
One of the following options is displayed:
– OFF (default value) = write access possible using PROFIBUS
®
– ON = write access not possible using PROFIBUS
®
Disable the write protection if necessary, ä 24
2. Enter the tag name (optional) DIAGNOSTICS SYSTEM INFORMATION TAG
3. Configure the bus address
Hardware addressing using DIP switch, ä 25
4. Configure the transducer blocks
The individual transducer blocks cover various settings such as unit, sensor type etc. The
parameter groups are grouped together in blocks as follows:
– Temperature sensor 1 Transducer Block 1 (slot 1)
– Temperature sensor 2 Transducer Block 2 (slot 2)
5. Configure the Analog Input function blocks 1-4
The device has four analog input function blocks (AI module). They are used to transmit
different measured variables to the PROFIBUS
®
master (class 1) cyclically. The allocation of a
measured variable to the analog input function block is shown below using the example of
Analog Input Function Block 1 (AI module, slot 1).
Using the CHANNEL function, you can specify the measured variables that should be
transferred cyclically to the PROFIBUS
®
master (class 1) (e.g. Primary Value Transducer 1):
• Call up the CHANNEL function.
• Select the "PV Transducer 1" option
The following settings are possible:
CHANNEL
– Primary Value Transducer 1
– Secondary Value 1 Transducer 1
– Reference Junction Temperature
– Primary Value Transducer 2
– Secondary Value 1 Transducer 2
Check hardware write protection
Configure bus address
Enter tag name
Configure the measuring inputs (see chapter 11 for detailed description)
Configure the Analog Input parameter (see chapter 11 for detailed description)
