logging date and time of an input contact

[raan]

Do you have any suggestions of how to log the date and time in the DM[n] array of when a input closes? I tried several approaches and must have something wrong because it bongs out every time I try to load the program into the plc. I need to log about 700 such entries on a 7 day basis and then reset at the end of the week.

What do you mean by "bongs out"? Do you mean you can't load the program into the PLC?

To log the time into DM[n], you just have to assign it:

DM[N] = TIME[1]      ' log hour
DM[N+1] = TIME[2]  ' log minute
DM[N+2] = TIME[3]  ' log second
DM[N+3] = DATE[2]  ' Log Month
DM[N+4] = DATE[3]  ' Log Day

N = N+5

If this use up too much memory you could compress the data into one variable such as:

DM[N+3] = DATE[2]*100+DATE[3]   ' represent as 101 to 1231
