CFU PA: PA profiles for field devices on PROFIBUS PA
PROFIBUS PA profiles and GSD files
For connecting field devices to a CFU PA, you must choose between the use of PA profiles and
device-specific GSD files.
PROFIBUS PA profiles enable simpler field device replacement than when device-specific
GSD files of the manufacturer are used.
Reasons for this are:
● The replacement device does not have to be identical.
● The replacement device only has to support the configured PA profile.
● If you are using SIMATIC PDM, you will find the PROFIBUS PA profiles in the following
folder:
PROFIBUS-PA > Profile > Ident Neutral > Siemens AG
When PROFIBUS PA profiles are integrated in the CFU PA, you can find the PA profiles of the
CFU PA in the catalog in HW Config in the folder:
PROFINET IO > I/O > Compact Field Unit > Compact Field Unit PA ... > PROFIBUS-PA
Profiles.
IOs in the field device
A field device can have multiple IOs. IOs describe the characteristics of the device. The term
IO corresponds to a PROFIBUS ID number.
When you use PA profiles, the ID number is replaced by readable text (e.g. 0x9701
corresponds to "Transmitter 2 AI").
Selected IO
A "Selected IO" identifies the behavior of the IO that the CFU PA sets in the field device
(examples: "Transmitter 2 AI", "Discrete Output 1 DO", manufacturer-specific IOs). The
configuration in HW Config normally defines the "Selected IO".
Setting the "IO" in the EDD of the field device is not permitted for a CFU PA.
If you use HW Config or SIMATIC PDM for configuring the field devices and the CFU PA, the
CFU PA stores the PA profiles read from the field device and the selected IO.
