Programmable controller with limit detection |
摘要 |
A programmable controller for sensing the status of sensing devices and controlling the state of operating devices in accordance with a stored program includes a position encoder input module which receives position data. In response to instructions in the stored program, the position data from the input module is compared with an upper and a lower limit stored in the controller memory, and if the data lies outside the limits, the controller logic unit is forced to a false decision.
