BRU.IMPIANTI Group srl usually makes automation systems  with:

• a PLC for system control (or some PLCs, with Profibus net connection, for most complex plants).
• a Personal Computer that is connected to control PLC (by MPI cable or ethernet net); this PC allows the operator to monitor plant working and set working parameters by a program with graphic interface;
  for small and not much complex plants, supervision functions can also be performed just by a device with a display with keyboard or by a "touch screen" display.
  We develop proper control and supervision software for every single automation system. 

We also provide manual command devices, such as push button panels, radio control devices, small displays with keyboard or "touch screen" devices.

Control program into the PLC has to:

• execute working cycles that are set and sent to PLC by operating panel (the PC or other interface device) 
• make optimizating choices when executing programmed tasks; it is particularly important for complex plants
• regulate working variables (temperature and pressure values, etc...) to reference values that have been set by supervision PC or by other operator interface devices
• notice and manage working troubles (such as motor faults, temperature measures over maximum threshold values, etc.)
• code working information so that they can be easily read by supervision PC and by other visualization devices

Supervision program on the operating panel has to:

• show, by animated graphic, several information about plant working (motors working or faults, position of mobile devices, etc.)
• let the operator see and set working parameters (automatic working cycles, reference values for temperatures, etc.)
• give proper warning messages if there are some troubles
• save on a database data about plant troubles 
• save on a database measures and other data about plant working
