configuration language is based on ie0611313 industrial standard and provides function block diagram (FBD) and ladder diagram
(LD), instruction list (IL), sequential function diagram (SFC), structured text (st) and other graphical configuration modes. The system contains about 220 functions
The algorithm library of energy block, the basic library with more than 200 graphic symbols and the extended library with a large number of 3D symbols.
The system uses the same set of configuration tool software to co
mplete the configuration and commissioning of process level, operation level and even fieldbus instruments, and uses the same
A global database.
The system scale has strong scalability. The single system supports 1 to 100 control stations and 100 operation stations at most. Each control
The station can support thousands of i/0 points at most, and the scale of the whole system can be expanded. The hardware of the system control station is all metal enclosure, which can withstand the most
Harsh industrial environment. The equipment can be installed in the cabinet or on the wall. The system complies with all current EMC standards and has CE standards
Annals.
