I just tested the download in Run with FW 2.2 and SP2 and it was very nice to see the PLC run light stay green the entire time. :) I guess with the pro version we can test changes before committing to permanent programming? That would be really nice but not nearly as important since we can put in debug options that run one piece of logic when the debug bit is set to 0 and the test piece of logic when the debug bit is set to 1. When online, just toggle the bit to toggle the code under test. :) Now, what is a changeover contact relay in simple terms? It has both a NC and NC for each relay output? I'm sure there is a good use for this, but right off-hand, I can not come up with one for the projects I'm currently supporting and developing. |
