Connection of process automation components and building management

With the Simat­ic S7-1500 HVAC, the pow­er­ful process automa­tion com­po­nents of the Simat­ic fam­i­ly are seam­less­ly con­nect­ed to the Desi­go CC build­ing man­age­ment plat­form. This new Siemens Smart Infra­struc­ture solu­tion enables opti­mal and ener­gy-effi­cient HVAC con­trol in indus­tri­al build­ings and for demand­ing automa­tion tasks.

Envi­ron­ments in the areas of research, devel­op­ment, pro­duc­tion and stor­age often bring with them spe­cif­ic require­ments for indoor cli­mate and plant avail­abil­i­ty. This is an opti­mal solu­tion for the wide range of automa­tion tasks in build­ings. The new prod­uct and the BAC­net Automa­tion Desi­go PX can be com­bined seam­less­ly and oper­at­ed uni­form­ly in one build­ing man­age­ment system.

It includes free pro­gram­ming of HVAC func­tions with the func­tion-test­ed HVAC mod­ules accord­ing to ISO 16484–2‑2 and VDI 3814. Engi­neer­ing and graph­i­cal pro­gram­ming in TIA Por­tal are fast, effi­cient and con­sis­tent through to the Desi­go CC man­age­ment sys­tem for user-friend­ly graph­ics cre­ation. Inte­gra­tion with SCADA sys­tems is also pos­si­ble. The HVAC solu­tion sup­ports the hard­ware vari­ant for fail-safe and redun­dant operation.

In the redun­dant vari­ant, the CPU syn­chro­nizes via PROFINET-IO ring or FO. Should a CPU fail­ure occur, the back­up CPU auto­mat­i­cal­ly takes over process con­trol. Simat­ic S7-1500 HLK meets the high­est secu­ri­ty require­ments through encrypt­ed con­nec­tions between the process con­trollers as well as reg­u­lar updates and inte­grat­ed secu­ri­ty func­tions such as copy and access protection.
