Thanks for those replies. I have attached the zipped program. The program is meant to solve a problem in an I/O poor machine control system. The I1 input turns on/off a mixing motor via Q1. Another motor (not part of this circuit) is driving a carriage towards a limit switch which is also input I2. The Q2 and Q3 ouputs provide 3 speed inputs to the controller running the Q1 motor. Another control systen turns the mixer motor on via the I1 input. A few seconds later the carriage reaches the up limit and the switch operates both I2 and stops the drive motor (via the other control system). The other system starts a 15 second delay fom this point, at the conclusion of which it drives the carriage away from the top limit a specified distance. Three seconds later B001 times out, starting B002 and B006. Both Q2 and Q3 chnageover and these outputs change the Q1 motor speed to the second speed. After five seconds at this speed B002 times out, turning off Q2, and changing the Q1 motor speed to its third value. During the five further seconds B006 is running, another controller turns off I1 and the Q1 motor decelerates to a stop. B001 locks the I2 input, and the B003/B004 gates ensure I1 can always overide Q2 and Q3. It is probably not be the most efficient layout, but it works flawlessly in Logosoft, and my question is why does it not work in the actual Logo?

Well, a bug in my particular version is rather unlikely, don't you think? The About lists: V7.0.30 (2011-07-11 15-34) Regards |

Hello, Well i simulated with V7.1.5 and with that version simulation behaviour is same as with real Logo. By the way the update you can find Here Regards, Marcjan |
Problem solved? |
