PLC
automatic process control system to control production ,testing process
,supply reliable working data for production scheduling and management.
This
system is mainly made up of industry computer and PLC control cabinet
and on-site control cabinet it is switched by the remote control and
local control in order to achieve operational consolidation, centralized
management, control, dispersion, risk dispersion.
The PLC main controller CPUintegration hasindustrial
Ethernet interface that connect PLC and computer to industrial Ethernet
switches. It not only achieve communications between the computer and
PLC to real-time display and monitor production process on computer, but
also get Ethernet interface on switch to associate the system into the
factory management network, then the system can uploaded data to the
management network. Last, the automatic control of whole factory come
to true.
The
industry computer is human-computer interaction interface to achieve
control. It accepts the data carried out by the PLC, first it
establishes a dynamic database, and then configuration software disposes
it timely .Last ,the function of dynamic display, automatic control,
data logging, reporting, analysis, curve query is achieved .
Main content of PLC system control:
ØChain start-stop and fault alarm of computer control equipment automatically.
ØThe system self-diagnostic function, the external signals recognition
ØAutomatic inspection, diagnosis, and treatment of Information
ØAutomatically display, record, print various fault of voice broadcasting equipment
ØReal-time dynamically display and control of whole production process
ØIt can be voice communications, such as drive notification, fault location liaison and production scheduling
ØIt can print statements or copy images manually or automatically.
ØAll
on-site sensors of stall, plug, wandering and high-performance devices
complete signal detection and a variety of real-time control together.
ØData transmission and communication networks
ØData records, reports, printing and statistical analysis of flow balance and packing balance
ØLevel monitoring alarm and prompt
Øspeed measurement, fault alarm and chain control of bucket elevator
ØPlug-proof, fault alarm and interlock control of all system
ØImportant statistical analysis of power consumption, extraction rate, the cost of groups
ØRemote computer network query and control of management staff
