Import of a technical question from the user Billym254 via PM. ----------------------------------------------------------------------------------------- Hello, i hope you are well. I have a Logo 8 PLC, and would like to achieve the following: I have 2 loop sensors ,a boom barrier and a PC. The first loop sensor is located just before the boom barrier and the other is located after the boom barrier. The mode of operation is as follows: Once the vehicle is at the first loop, the loop will sensor it, then after the computer operator on the PC will need to key in some data, afterwards he/she will click an open command which will then work with an and function of the first loop, after which the boom barrier opens. Afterwards, the car will the arrive at the second loop and once it has finished going through the second loop, the boom barrier should then close and the process starts all over again. My major challenge is how to ensure the constant communication with the PLC to await the command, any assistance will be highly appreciated. Thanks. |
