    PLC directional selection in the elevator control on the application layer Set the direction of the elevator, by the stopping time T control relay, which pull in an elevator running, open the door to stop the elevator after the delay of release. LC control the implementation of

    microprocessor-based programmable controller technology combines computer technology, automation technology and communication technology, with user-oriented programming language, is a complete, general purpose industrial control devices. Relay logic control system based on electrical schematics, determine the control flow, logical

    relations,moncler italia, and input and output signals work. The system selects the Mitsubishi F-40M PLC, the preparation of an external input and output signals in turn control and PLC code corresponding to the input and output relay code table,goedkope uggs, the I / 0 allocation table 1

    corresponding ladder diagram (see Figure 4). Taking into account the characteristics of PLC work, in order to achieve reach the floor (a floor signal) can be given for speed signals. At the same time to eliminate cross the bridge in the floor and the landing door Summon the signal, so the additional time and relay the floor in each signal, the signal given by the elimination of exchange rate lags behind the signal, K must be greater than the value of a calculation period (the average time required for the implementation of a means exaggerated × the number of users of instructions), the system K> 12s × 241 step by 2.89ms. So take time to relay K Sheng small 0.1 seconds. time is set for Speed 2 seconds, and the command car priority from the beginning to open the door for Speed is set to 4 seconds after the delay. According to this ladder and the F-40M PLC programming instruction sheet statements, procedures, a total of 241 steps (a little). by the programmer to program Enter the PLC, the external signal input, PLC in accordance with procedures that can automatically run. 4 In the study, the control system functional requirements,uggs kopen,

    combined with I / O allocation table and the ladder, use the appropriate components, the external wiring diagram drawn PLC ( Figure 5). connected to PLC power supply, the \various features of the original system, and ensure the flexibility of the control system and simplify the original control system, improve system stability and reliability. circle 5PLC external wiring diagram 5 More articles related to topics?
