An improved plant overview through decentralized process fields – here through SIMATIC PCS 7 TeleControl V8.0, the external stations are integrated into SIMATIC PCS 7 V8.0 so that the operator is not aware of any difference between central and remote automation in terms of operating philosophy and alarm characteristics. At the same time, SIMATIC PCS 7 TeleControl V8.0 can not only incorporate newly designed remote terminal units into the control system environment but also migrate sub-systems in the external fields. The revised version also makes it easier to set up hierarchical system configurations.
