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.
