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.

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.
