Migration of a process control system based on APACS+/QUADLOG controllers with the innovative SIMATIC PCS 7 OS operator control and monitoring systems from Siemens provides the opportunity for retaining proven functions and for significantly increasing the functionality and performance at the same time through specific modernization. Existing operator and engineering systems can be modernized with SIMATIC PCS 7 while retaining the APACS+/QUADLOG controllers and the nested I/O levels. This enables customers to migrate their existing systems efficiently and economically without having to replace any controllers, I/O devices or their wiring, and without any loss of investment into the system configuration.
In addition, excellent alternatives are provided at the controller level by the SIMATIC PCS 7 AS 410 automation system, especially for plant expansions. These are supported by the controller-controller communication via Industrial Ethernet Modules (IEM) and by SIMATIC PCS 7/APACS+ operator systems which can communicate with both APACS+/QUADLOG controllers and AS 410 systems by dual channel.
