Cervepar is a Beer Company from Paraguay located in Assunción City, South America.
PROFIBUS PA devices from smar (21 FP303-Profibus PA to pressure converter, 4 FI303-Profibus PA to current converter and 1 FY303 - Positioner) are integrated in the Beer Fermentation Application, performing output signalling and control information. These devices are working at same level with Endress+Hauser transmitters, interfaced by link Devices (IM157) and DP/PA couplers from Siemens. They are integrated into Simatic Software (STEP 5 and STEP 7) and performed by Siemens PLC host.
An important point is the integration between PROFIBUS PA devices and 4-20mA devices using the PROFIBUS PA to current converter from smar(FI303). All field devices configuration was done using Simatic PDM and Commuwin. Although the presence of different manufactures on the bus, the system interoperability and startup was excellent and the plant is operating fine after 4 years of installation. The cost reduction and the simplicity of PROFIBUS were confirmed.
