I do have DL06 PLC with 5443 of 7680 instructions memory used and 230 V memory positions used as comparison values. I’m trying to log somehow analog inputs from F0-04AD-1 into the memory. I do not need to do it very often (probably 4 times per hour) but from two inputs. Is there some easy program to do this? I’m using about 20 stages in my program, so I guess I have to put instruction for logging into each stage… I also need to log events on discrete inputs X10 and X11 which should not to appear very often (probably once a month) My question is: 1) Can I use internal PLC memory? 2) Is there some simple instruction that won’t take much memory ( I still have 2237 free for instructions) 3) How do I download stored values to some table (I do not need send data over modem or anything like that I just can plug laptop once a month to PLC and download data. (approx. 5760 values each month for analog inputs and very few X10, X11 triggers with date and time of course)

I currently do this with internal PLC memory. I have DSData, and I have an excel sheet that grabs the data in a manual fashion (via ethernet).
I have one major difference between us though. I'm storing 19 different addresses a total of 48 times each. This is 912 V-mem's.
You, on the other hand, have 5760 not including the data stamps. (I believe there are just under 8000 spots available.)
Anyway here's how I do it...
---|trigger|---------LD K30 (48 moves)
LDA O10000
MOV V10001
This moves V10000 to V10001 to V10002 etc 48 times.
If you were to use V10000-V17777, you could do...
---|trigger|---------LD KFFF (4095 moves)
LDA O10000
MOV V10001
Or if you use V1200-V7577 then LD CFF (3327 moves).
For X10 and X11 you could just use LDA O40400 and have your excel file look for particulars.
In your case there is data logging software out there that can accomplish this. For me on a small scale it works out. Your excel sheet would be evil to input. Even mine, with just 912 http://forum1.automationdirect.com/board/eek.gif , took too long.
Also would he have issues with scan time on a move that large?

This datalogger works with the DL06 and writes to compact flash cards.

You could download values from the DL06 using Remote Set Point assuming that the DL06 has an ECOM module. But we have plans to develop a version of Remote Set Point that will communicate directly to a serial port using Modbus.
