Siemens SIMATICS PCS7 Manuale Utente
Totally Integrated Automation
3
Integration of the telecontrol technology in TIA has made it
possible to combine the automation of central plants and the
monitoring of distributed units in a single process control
system.
possible to combine the automation of central plants and the
monitoring of distributed units in a single process control
system.
Homogenous operator control and monitoring using a com-
mon control station, uniform configuration with the same
engineering system, and consistent utilization of hardware
components from the TIA product portfolio result in signifi-
cant savings with regard to investments, operation and
servicing.
