IOT202020 / s7-12000,

For the memorizing portion of your assignment - roughly:

1> Convert the inputs to network bits to construct a VW word.

2> Use a counter with comparators to indicate 1 to 8 saving positions

3> Use the "Mathematic instruction" with output when EN is off, set to last value.

Do say "Hi" to Gregg Johnson for me if he is the mentor that gave you the assignments. I always liked the expanded elevator assignment he gave the students.


Cheers.

HI,

THATS A WONDERFUL PRG.

I LIKED ALL YOUR PRG. IXO65, AND I DO LEARN A LOT ALSO.

WELL I DONT MIND IF YOU GUYS SHARE YOUR PROGRAMS HERE, AND BECAUSE WE DO GET TO LEARN A LOT REALLY, I DONT MIND WHAT PEOPLE THINK , BUT YOU PROVIDE A WONDERFUL PLATFORM TO LEARN MORE ABOUT LOGO AND DISCOVER THE REAL CAPABILITY WHAT WE CAN PROGRAM THROUGH LOGO.

WE DO MAKE OUR OWN PROGRAMS DEFINITLY, BUT YOU DO IT MUCH BETTER WAY. BY USING SPECIAL INSTRUCTIONS AND REDUCE THE PROGRAM SO SIGNIFICANTLY.

KEEP SHARING BUDDY!!

THANKS AND BEST REGARDS,

Hi,

you could use the Data Log function to store the last 20.000 sensor activation's.
Just trigger it with every I1-I8 and store values you want on the MMC.

hello ixo 65,

sorry i might have not expressed it properly.

about that last point numer 8.  ;  i meant, i would like to know the last 10 sensors [actuated] activity in correct order.

for EXAMPLE :  sensor number 3 actuated , then sensor number 7 actuated, then sensor number 1 , then sensore number 3 on, then sensore number 5 on,   then sensor number 3 [again] and like that way,  the last 10/ previous 10 sensores actuated in correct sequence.

in that way we can make out how the machine is exactly behaving or just moving between fixed few sensors only.

so want to have the record of [atleast]  last 10 position in correct sequence.

did i make it clear?

thanks!! 

How should I know, without a description of the sequence of sensors, when which sensor comes in the right order? I have no crystal ball.....

And the LOGO! has no memory like an S7 or similar.

Hello ,

about that FIFO logic, i must say thats a wonderful program, thanks to ixo65.

and yes i do agree to vkkepl, about learning and discovering more and more about Logo and its application, through this forum and the experts sharing ideas and helping out the needy ones,  and neither do i care what somebody else thinks.

@Adrian,  i have never done the data log, but its a wonderful idea and i would love to learn it sometimes for sure.

regards,
