Hi there,
I am a newbie
I did some programming on Siemens LOGO and some troubleshooting on Siemens S7.
Now I have to write a progamm for a machine
( big sandwich flipper ).I tried the common way
but ended up having over 30 Rungs! just for the
9 step ( Drum switch )part.
I would like to use a Sequencer but have trouble with programming and addressing it to my
Inputs (15 Limitswitches)and
Outputs ( 8 Solenoids for hydrolic cylinders )
on a Micrologix 1200
I used Sequencer SQO for my Outputs and
SQL for the Inputs because in every step (9),one output must be activated and advance the sequencer to the next step when a number of Inputs are become true.
I programmed the 9 steps into the data table
SQL N7:0 and SQO B3:0.
Now I can not figure out how to address the inputs and outputs to the SQL and SQO.
Do I have to make one rung for each
Input and SQL #N7:0 to #N7:14 and
one rung for each SQO B3:0 to B3:8 and Output.
Or is there a simpler way ?
Thank you very much for any help
Heinz
