ge control(fullautomatic control, automatic control, order to move a control) with surveillance, make use of Intouch7. 0 engineering software packages provide a good person machine dialogue boundary but obtain concerning parameter and equipments appearance information from the PLC by searching a way, keep a view manifestation to e out on the CRT by good sketch type, print a necessary data in the meantime and be provided for lord to control and manager instruction and control boundary but include the system total diagram, system cent diagram, imitate the quantity general chart, parameter a constitution, report to the police a window, history trend and register a window etc. boundary the system total diagram, circulate the personnel can keep watch on signals, such as all movement appearances, equipments trouble and liquid which control an equipments and discharge...etc..Operate a personnel in the system the cent the diagram can carry on a single machine point to move to circulate an operation to all control equipmentses, bee the set automatically circulate operation or the whole factorieses fullautomatic operation bine the meantime place of honor machine 2 and do a plait distance a control room to establish another an inset type emulation to hold, is been one control by the place of honor machine, in order to keep the craft process of the view manifestation whole factory and main parameter value. 1. 2 The PLC stand According to wastewater treatment of two part, the spot the long range of the equipments the control output and the spot the signal collect to control a station pletion from two PLC wood native control station control the space grid, sewage promote a pump house, Pu spirit to sink sand pond39。 s etc. to prepare a processing PLC2 native control station controls dirty mire to dehydrate, press to filter machine etc. department..PLC3 native control station control SBR living creature processing , the on the spot native control station is each to establish an operation terminal to establish each, be responsible for at native to establish each control on the scene.(automatic control, order to move a control) The spot is each the physical parameter that the supervision order and include water level, temperature, discharge and turn soon, electric current39。 s etc. imitate quantity, from to in response to of an appearance spread a feeling machine or change to send to a machine examination to e out and change into the electric current signal of the 4~20 mA, through shield inside the PLC that the electric cable sends to each statures system, from the PLC picks up a people through various mold piece sample telemunication , imitate quantity control the signal send to performance anization by the 4~20 mA electric current form after being output by the PLC, control performance anization of action. The Modicon Quantum series PLC of Schneider pany is satisfy liberal of, according to standard of work conjunction and the spot total line conjunction etc. application the technique provided various work a choice, support Modbus, Modbus Plus(MB+), the long range I/0, TCP/IP etc. work conjunction, have stronger and , the wastewater treatment is convenient to arrive of the PLC choose the series of Modicon Ouantum of use Schneider. 1. 3 Correspondences MB+agreement is the Modicon pany release of an open type of the adoption IEEE802. 4 correspond by letter 5 agreements the spot total line of card +the work together other works pare to have a set of simple, the investment be little, work speed quick, correspondence the stability strong etc. characteristics, it make calculator, controller and other data sources through an usage double wring line or fiber optic cable Be a body to together carry on correspondence at the whole work the CPU mold piece of the Modicon Quantum series PLC imply MB+correspondence, therefore correspond by letter a work to choose to use MB+ control two machine, two control stations with native PLC of ro。
