Hi, i'm working on an already written plc program using twido that controls speed of a drive through an hmi (magelis). unfortunately, no documentation were developed with it. Now i like to add speed option to the drive using using a selector switch wit three positions for three different speeds.
i know how to program these inputs and outputs, however, i'm not sure where to program these speed word in the existing ladder progarm. the three speed are 1000, 2000 and 3000 for example. today these speed are being selected through the hmi. i hope my question is clear enough.
Please let me know if you can you help? dean
