A computer system for controlling temperature in a two-state mode and by means of a PI controller in an “intelligent building”

The article presents the application capabilities of the LOGO! controller produced by the Siemens company with respect to heating control in an automated “intelligent building”. The wide range of capabilities of the logic controller finds its reflection in practical implementation, as illustrated by means of a computer simulation example prepared in the LOGO! Soft Comfort v6.0 program. The work presents a comparative analysis of two programs serving two-stage heating control: with and without hysteresis, as well as a control program for an “intelligent” holiday cottage. The article also presents the results of parameter calculations for the B007 analog adapter, based on the examples of sample heating curve characteristics. The wide range of capabilities of the logic controller finds its practical implementation on the basis of examples of PI controller operation simulations in the LOGO! Soft Comfort v6.0 program.
