Sharing up/down keys
« on: January 12, 2004, 06:03:54 AM »
I'm using a MD-HMI keypad with a T100MD888.  I have 3 categories of parameters that I would like to access via a dedicated key on the MD-HMI for each category.  I would then use that same key to select the parameter within that category. (same as in your setTimerCtr_SV example). I can see how to increase/decrease the set value for the parameters using 3 sets of up/down keys, one set for each category.  How do I do it using one set of up/down keys.

Thanks

In our SetTimeCtr_SV example we use one key ("select" input) to select up to 6 parameters (3 timers and 3 counters) - you can do the same here. Just one set of up/down keys and 1 select button.

If you have the HMI, it seems to make more sense to me to use the keypad to enter your values instead of up/down key. In this case, just use a function key (say F1) as the select key to select different parameters (show the chosen parameter on the LCD), then use the numeric keypad to enter the data.
