PM861AK01 RS232/RS485 interface

With the increase in the use of years, the workshop in the high temperature and dust production environment, making the main control computer connector aging, poor contact and corrosion of the circuit board is serious and easy to lose parameters, the phenomenon of crash. Easily caused by the control action is not normal, signal distortion, affecting the timing, action control device’s normal work (or cause damage); On the other hand, the display requires more input parameters, cumbersome operating steps, the display is not intuitive equipment maintenance is larger, the computer spare parts are not available to buy domestic, affecting the production schedule. It is difficult to meet the needs of modern industrial production. In view of the above disadvantages, we put forward the corresponding transformation programme, the use of more advanced technology platform —–PM861AK01 series and human-machine interface (touch screen) products to replace the original monolithic special control computer.

PM861AK01 transmission part of the operation is more normal and basically intact, so the principle of improvement is not to make improvements to the transmission part, only the original electrical computer automatic control part of the transformation. Redesign drawings, according to the characteristics of the pressing process to prepare the corresponding application. Selection of general PLC, touch screen series system to complete the replacement of man-machine dialogue and automatic control of this equipment. Control instructions from the system touch screen centralised operation, the system through the operator instructions output control signals. PM861AK01 required applications according to the process operation requirements by online debugging modification and improvement, has made the machine stability, so that the degree of automation to improve the machine, stable and reliable performance, enhanced functionality, easy and intuitive to operate, reduce labour intensity, greatly improving production efficiency. Reduce the operation steps, no need to input parameters, can make the operator more quickly familiar with and skilled operation of the machine. It can be improved or increased in real time according to the process requirements, and spare parts are easy to purchase. High degree of system integration, the electrical structure is simple, intuitive and easy to check. Reduced failure rate.
