Henan Wan Jilv the industry limited company is a
fair produces the aluminum ingot, the metallic sodium, the cement and
the electricity generation to a body large-scale rural enterprise,
recently prepared for construction a 80,000 ton anodes carbon
production line, core control product was PLC. Passes through
various factories PLC product carries on the comparison to the market
in, with advantage when FOPLC by its disposition nimble, the support
many kinds of communications way, the module integration rate high,
the system reliable, the man-machine contact surface function
formidable, the convenient application, the higher natural price and
so on were more than superiority to obtain Wan Jilv the industry
approval. Simultaneously considered and when advantage the
company consummates the complete technology and the good post-sale
service ability, Wan Jilv industry finally firmly has chosen and when
the advantage FOPLC, and by with advantage when is responsible for the
entire control system the complete set.
This anode carbon project altogether involves the refinery coke
?fever, the asphalt melts, the remnant level broken, the system
sticks, takes shape and cooling, 炭块 the storehouse and the
roasting, the roasting haze purification and so on many construction
sections, the control point is dispersible, the total control point
amounts to 3,000 above. User through to with advantage when
provides several plans carry on the verification comparison, the
definite scene various construction sections system if between the
long-distance station the network uses Profibus-DP the communication
way. Namely each construction section is a control center,
establishes CPU, the long-distance station disposes the Profibus-DP
communication module, CPU and between the long-distance station
becomes a whole through the shielded twisted pair company, causes the
controller to be allowed very conveniently to visit in this system
wilfully an input/output spot. ?burns in the refinery coke
with the system sticks two control centers respectively to establish
an on position monitoring machine, time the movement and advantage
Focsoft 3.1 monitors software, uses in to monitor PLC the
process information, processes the data report form, in order to
dispatches the personnel to understand the field work condition, and
according to corresponding authorization to PLC transmission order
data. At the same time, when with advantage FOPLC product
support by condition international open style main line agreement and
so on net TCP/IP, Profibus-DP, AS-I, Interbus-S, CANOpen, DeviceNet,
LonWork, therefore, this control system may with conform to the
corresponding agreement any factory equipment realization connection,
has provided the broad space for later system function expansion.
This project smooth implementation, has fully proven and time
the advantage FOPLC product not only the single plane control may
reach DI/O 1,024, AI/O 256, moreover relies
on its good open style network communication function, may complete
the large-scale system the control, the realization and overseas
famous PLC produces the performance which the physical appearance
compares favorably with. At the same time, with advantage when
the FOPLC product by its outstanding performance/price compared to, is
at monopoly position in the overseas PLC control system today, will be
the national brand PLC industry achieves the small space. |
