Non-Voltile Mem and the T100MD

Is the Max-RTC module required to save the counts from a few counters?  It is important to not save I/O status after resuming from a power failure. But I do need the counter values.

Dan,

I am pretty sure that unless you periodically write to the EEProm the only way the values will be saved is with the Mx-RTC.

If you use MX-RTC and leave DIP switch #1 ON, then all I/O status and internal memory status are kept when power failure occur. If you want to reset the I/O status after a power failure, then on your 1st.Scan function, clear out the I/O by running statement such as:

 OUTPUT[1] = 0   ' clear output #1 to #16
 OUTPUT[2] = 0   ' clear output #17 to #32
 RELAY[1] = 0    ' clear relay #1 to #16.
