| Abstract: | In this paper in allusion to the shortcoming of the current Programmable Logic Controller of which processing capabilily of analog is weak, designing an analog extended module of PLC which can satisfy the demand of micro computer control system of medium small sized water power station. In allusion to the concrete projecg, also presenting the basic priciple and presenting the basic priciple and realization method of analog extending of PLC in detail, and providing the frame of hardware, software and primary experiment data. |
