For the connection of control valves in the still house, a Zone 2 certified LB system from Pepperl+Fuchs is used in the distillation process. Depending on the distillery size and the number of stills, up to 200 control valves may be necessary for the distillation process.
PROFIBUS PA is applied for all measuring field instruments such as level, pressure, flow, and temperature measurement. The high-precision digital transmission of PROFIBUS PA via FieldConnex fulfills the requirement of precise measurements and accurate signal transmission.
The FieldConnex PROFIBUS Power Hubs in the control room feed field-mounted segment protectors, which reduces wiring costs while ensuring diagnostic information is easily accessible. The configuration is done via GSD files, allowing all measurements to be displayed in the control room with digital precision. Remote configuration, alarms and diagnostics from field instruments are transmitted to the maintenance system via PROFIBUS PA, enabling users to proactively review plant performance. In order to avoid information overload or alarm flooding, the data is routed two ways, with only measurement values reaching the plant operators. Maintenance technicians and staff have full access to all other data, allowing them to keep the plant’s processes functioning at a high performance level.
