logixpro silo simulation exercise 1 solution

HINT #2: If you really want absolutely no spills, you should examine the silo discharge chute very closely. To get around that obstacle and run with no spills takes some more-advanced techniques than would normally be required. This LogixPro Exercise was programmed by the creator to produce spills any time a program switch is changed, or the sceen focus goes from one screen to another, or any thing else that a student might do while running the simulator. HINT: If I were you, I would stop looking at a non-working progarm, and instead look at one that has been tested and does work, and does not allow ANY spills under ANY condition. You will not be able to do it without adding some similar logic to your program. However, the devious course instructors figured out how to add extra student work by requiring that Exercise #3 be programmed to allow the selector switch to be operated WHILE RUNNING, WITHOUT SPILLS! To do that, see Post #14, Rung 001. Most processes are shut down while such changes are made. The original exercise was not designed to switch the operating mode while RUNNING. Now you have described the problem concisely. The START switch will have to be pressed to start the control system again.This happens when i switch from B to a when prox. If the STOP switch is pressed the system will stop, and the RUN light should go OFF. Move the SELECTOR SWITCH back to position A, depress the START SWITCH to restart the system for the next 10 boxes. To restart the process, move the SELECTOR SWITCH to position B to reset the counter. Once 10 boxes have passed the PROX SENSOR, the process should shut down.

Once the box is full, the FULL light should come ON, and activate a second timer to wait an additional 5 seconds.Īfter the last 5 second interval is complete, the box should move away from the fill station, and the FULL light should go OFF, so the next box can arrive to be filled. The FILL light should go OFF when the box is full.

While the box is filling, the FILL light should flash ON/OFF at a 1 second interval. The first box arrives at the filling station and activates a PROX SENSOR, then activates a 5 second timer to pause the process then starts filling the box after 5 seconds is complete. When the START switch is pressed, the RUN light should come ON. Follow all the Project Parameters listed, include an explanation of how your project works.ĭesign a program that will move boxes to a filling station while the SELECTOR SWITCH is in position A. The project will involve the Silo Simulator within LogixPro 500. Silo Simulator project within LogixPro 500
