I am new to the use of the FO-04DAH-2 analog card and would like to ask if someone could please explain in more detail how this card works. I am using this module in my DL-05 . On pg 9-7 of the manual, it talks briefly about how to configure this module, what memory locations are used, and something about pointers. My application is that I want to simply ramp up to the maximum ( 65535 ) over some short time period, say 20 seconds. Then ramp back down to zero in another 20 seconds. I was thinking to have two parts to the PLC program. One to count up and the other to count down. Use a timer to act as a trigger to increment the count. So the ramp up and ramp down would have a small stair case appearance. Memory location V7700 is used to configure the data format for the module. But how to you load 0084 to V7700 ? Don't know how to do this. Would like to use binary, since I am most familiar with that. On pg 9-9 it looks like I could use the IBOX Instruction to setup the pointer, memory. But that about all I can get out of it. Using the 0-10VDC signal to ramp up a small fractional hp motor. The 0-10VDC signal will be wired to a VFD that will then ramp up the motor to the maximum hz setting in the VFD and then ramp it back down. Any help is appreciated.

try using the I-Boxes, you don't have to do anything other than the data entry in the I-Box...no additional setup or programming needed.
here is a screenshot of what you 're describing, an analog out I-Box, assuming Slot 1, set for binary, outputting all four channels

also, for the 'stepping ' part you described, you should look at the edrum instruction... you can configure this based on time or events to trigger stepping through the drum.

Try this text file copy of a program for the ramps

Thanks for the info will have to read up on the various ibox info.
The text file was alittle over my head at the moment. Will try and figure out what the various acronyms mean.
STR ? SPO ? LDD ? OUTD ? TMRF ? STRN ? LD TA1 ? MULD ? DIVD ?
OUTD ?
Sorry for being so ignorant, but I just haven't used the Automation Direct plc programming language at all except to do some very simple ladder logic recently.
Thanks again.

Here is the link to the main manual. Chapter 5 has all of those acronyms in it.

Is the DL06 applicable to the DL05 that I am using ?

Save the text file on your computer, and then use DirectSoft to import the text file as mnemonics.

Open a new empty program. Use 'menu ' - 'Import ' 'Program '. Point to the text file. The ladder will be created. But if you will be using the DL PLCs you should read the manual.
While working on any program you can use 'View ' - 'mnemonic View ' to see the 'mnemonics ' (the text version of the instructions and program data) of the program. This is the information which can be 'exported ' the 'imported ' to transfer the logic of the program. Note: the values in the data table (V Memory areas) are not transferred by using this method.

Sorry, I grabbed the wrong link. Here is the DL05 Link .
