Excellent tutoring video. It helps to learn when I can slow the process down by rewinding and watching until I 😂 get a clear picture of what's happening. I can practice at my own pace.
fantastic vid, I'm currently running this sim so that when the air out is 100% the first compressor will kick in at 120/20 and the second will kick in at 110/20. both will run until full and then repeats. but if i wanted to put a compressor e stop where would i put it in?
Now how would i program it to where if i only have one car going that the green light would stay on for that car, and would stay a red light for the other lane with no car, vice versa
He mentioned previously that he likes to keep the lights at the bottom, so I guess he added the lights but never showed them. For the Idle Light, I added a run with an XIO linked to the B3:0/0 binary bit and an output to the B:2/6 Idle Light, so when the bit is deactivated, the idle light is on. For the full light, I used an XIC linked to the B3:0/0 binary bit and output to the O:2/5 Run Light, this way if the binary bit is active, the Run light is activated.
@elmeonline9932 Thanks for the video! Would you have any idea why the timer for the "Fill" is not working?(even though the tank fills up - for 8 seconds) The timer for "Discharge" works just fine. Thanks again!
Nice to see young people learning and developing ideas for off grid and sustainable living. Off grid 20+ years with just a 400 watt solar power system and happy to help with ideas for realistic off solutions.
I guessed could do it with a flip-flop, but used a similar latch based on a 2-bit relay counter(not the CTU instruction) because using OSR isn't allowed. It's the same result with about 40 inputs. Actually, this job could be done only with 5v-220v relays and push buttons.
This is more of a logic puzzle to figure out than a real world scenario. In real life you'd most likely have a VFD controlling the motor, then the motor would go into a gear box taking it from 3600rpm down to conveyor speed. A real conveyor would have an acceleration and deceleration rate programmed into the VFD most of the time too.
I am learning plc programming in my off time. I have gone through all the exercises in about a week. It all seems pretty intuitive so far. Assuming the advance bottle simulation goes the same way, how real world application/ skill based would you day these lessons are vs real world application? Trying to get a judge of my own accomplishments/knowledge. Are there any other simulations out there for PLC training or electrical troubleshooting?
Once the last timer is done in this setup, all of the lights momentarily turn off. The cars' response to no lights is to go so it ends up being a small window of time for crashes to occur.
Might I suggest a final rung that does an examine if closed -] [- T4:4/DN with a (RES) T4:0 reset Timer Solved my Crash problems.... If you do this you have to remove the examine if open T4:4/DN from rung 001.
How do you adjust the counter preset value in Advanced Batch MIxing Lab without manually doing it in the program? I was thinking entering counter values with I:3 (BCD) but the number values are confusing.
I think you'd want to manually set the the PV. When the accumulated value reaches the PV is when the CTU or CTD output will go true. If you're wondering how the accumulated value increases or decreases, it's from the CTU or CTD input signal going from false to true. Hope this helps.
@@elmeonline9932 It is said in Exercise#2 that user will have to set the desired batch count, as well as product ratio, using the control panel thumb-wheel switches. I can't figure out the type of number thumb-wheel switches produce (I:3).
Hey pal.. great videos.. i'm completely new to all of this and this is my first scene in Factory, do you have a little clue how to solve the issue when the discharge button is normally closed..? i can't seem to figure it out.. 😞 thx in advance..
Without looking at your exact logic, I can't say for certain. If the "real world" contacts of the discharge button are NC contacts (like most stop button contacts are), you could pretty much do the same thing as I did with the fill by changing the instruction in the ladder to a normally closed. It gets confusing, but a normally closed ladder instruction addressed to a NC real world contact will be open until the button is pressed. Hope this helps.
