Thread Content
The format is as follows; everyone can also add more details. Manufacturer: Siemens Application area: Chemical industry Number of application points: 800 Application model: S7300 315-DP Duration of use: 3 years Known faults: None Number of computers: 4 Additional information:~~~~~~~
Manufacturer: HoliTech. Application area: Non-ferrous metal smelting. Number of application points: 1099 + 2009 + 2106 + 2252 + 2743 + 1651 + 1357 + 1387 = 14,604 points. Application model: MACSV. Duration of use: 3 years. Any known faults? None. Number of computers: (3+2) + (4+2) + (4+2) + (4+2) + (5+2) + (3+2) + (4) + (4) + (3); these correspond to processes such as raw material handling, leaching, sedimentation, evaporation, decomposition, control of filtration, roasting, etc. There is an additional scheduling console in the computers. There are also two PLC control cabinets (200, 300); the number of points in those cabinets is unknown. There are two touchscreens as well. In the gas station, there are 8+8 PLCs of model 200.
