Title: creating Menu System in ladder
Post by: Andy on December 08, 2003, 11:06:44 PM

As i'm quite new to ladder programming, i have trouble imaging how to make a Meny System, which will be required in my case.
When i'm counting all settings inputs, then i get about 26 individual Setpoints.
Should i place the setpoints into the DM[n] Area ? I want to use just 3 Buttons (up,down,Enter). Kindly asking for your support / ideas / samples

Thanks in advance

Andy

I assume you are using the LCD display to create a menu structure. You will need to use a memory location (DM or A to Z) to keep track of where you are and then a custom function will display the correct text based on the pointer.

If you want to use 3 buttons to change set point, there is already an example in your "samples" folder called "SetTimerCtr_SV.PC5" which you can follow to learn to change any of the 3 timers or 3 counters in the PLC.
