4.1 Profiles
The UFC030 (UFC 3 Beam) supports the PROFIBUS -PA Profile Version 3.0. Additionally, all relevant parameters of
the device are accessible via the PROFIBUS-PA interface (if the manufacturer specific Ident-no is chosen and the
manufacturer specific GSD-file version is used).
The UFC030 (UFC 3 Beam) defines the following blocks:
•
One physical block.
This block contains the parameters defined in Profile 3.0.
•
One transducer block for ultrasonic flow meter devices.
This block provides the parameters and functions defined in Profile 3.0. Attached you will find here all the values
not defined by the profile.
•
Three “Analog Input (AI)” function blocks: “Volume Flow”, “Speed of Sound” and “CORR. Volume Flow or HEAT
Flow (depends on the current device type selection)”.
•
Two “Totalizer (TOT)” function blocks: totalized “Volume” and totalized “CORR. Volume or HEAT (depends on
the current device type selection)”.
4.2 Services
The UFC030 supports the following PROFIBUS-PA services being defined in the PROFIBUS-PA Profile V3.0:
1. DDLM_Set_Slave_Add
2. DDLM_Get_Cfg
3. DDLM_Set_Prm
4. DDLM_Chk_Cfg
5. DDLM_Slave_Diag
6. DDLM_Data_Exchange
The services mentioned above will enable the customer to set the PROFIBUS-PA station address (1), to configure
the data telegram for the cyclic data exchange (3/4), to read back the current PROFIBUS-PA configuration (2) and to
read the current Diagnostic data (5).
The service “cyclic data exchange” (6) will be used to transmit the function block output values (measurement data)
to a master.
4.3 GSD Files
All available GSD files of KROHNE devices – including those of UFC030 (UFC 3 Beam), of course - are supplied
together with each device. The GSD file contains information that will be needed for project planning of the
PROFIBUS -DP/PA communication network. The relevant data files must be loaded into the project planning
system/master system before start-up of the bus system.
The UFC030 (UFC 3 Beam) is supporting the entire PROFIBUS-PA profile V 3.0. The device has two Ident-no.
and two GSD files:
•
Ident-no. “F501” belongs to the GSD file KROHF501.GSD and includes the complete functionality of the
ultrasonic flow meter.
•
The application of the manufacturer independent Ident-no. “9741” (GSD file “PA_9741.GSD”) provides
interchangeability of devices, i.e. an exchange of mass flow meters of different vendors.
Please follow the instructions in the manual of the host supplier when installing the GSD File (KROHF501.GSD,
UFC3_B_n.bmp, UFC3_B_n.dib) into the PLC.
