I'm still a novice, I was able to connect my two GS2 to the DLo6, (start/stop preset speed as show in P5-19). I wish to have their speed tie to an FO-2AD2DA-2 using the pointer method. I'm able to control one drive but not the second one. I use the MWX and MRX where the drive #1 is V2000 and drive #2 is V3000, the Fo-.... is set up that the LDA is on o2000( V701).This will run the drive #1 If I set the LDA to o3000 the drive #2 will run. How can I set multiple drive to go on the same V memory, I tried different solution with no luck. I checked the manual (dlo6, Option Module and GS2 ) with no answer. I was able to go that far with your help and this last step is blocking me, I may miss the point somewhere.

NavInc,
Is there a special reason for using both the coms and a analog out?
Unless I'm missing something you could accomplish the speed at the same time as you were turning the drives on and off with the com port.

That what I try to do, I just the analog Input , I found out that if all the slave are on the same V-memory they will both work, but the plan is to have the drives having their own address, for fault reference.
I download the two sample but still not got it .I really wish I could speak with somebody.Or have a clear sample. :0(.

It's unclear to me the relationship of the analog input to the MODBUS communications to/from the drives.
Are you bringing in a speed reference, perhaps from a potentiometer, through the analog card and wish to send a reference to the drives via MODBUS communications?
If the program or at least the section dealing with the control of the drives, is small you could export that to a text file then cut from the text file and paste it to a post here. That may help give us a better picture.

NavInc,
It doesn't get any better than this! Bernie (bcarlton) has offered to help if you post your code. Do not miss this opportunity.
PS. to get the code in text form go to file, export, program, save as something you can remember and find. Open this file in notepad copy it and paste it in your response.

I changed some starting addresses in the mwx and mrx boxes. If you get a "CE03 " error on the drives change them back.
Here is a quote from the options manual explaining why you were only able to get one drive to work on analog.
This loads an octal value for the first V-memory location that will be used
to store the output data. For example, O2010 entered here using the
LDA instruction would designate the following addresses: Ch1 â€" V2010,
Ch2 â€" V2011
So when you used v2000 that went to the first analog channel and v2001 went to the second analog channel if you had the drive running there would have been a 1 in v2001. This would give you almost no voltage on the analog out channel #2

Vaugh thanks for your time, here is what should happen, X0 turn the system on, X1 turn it off no matter what the analog input in CH1 is.( not using Ch2 in or out)
NOW where I get confuse is how to use my analog signal to start multiple drive, if drive # 1 is V2000, speed reference and drive # 2 is V3000, my main problem is that I can not find out, lack of sample and mostly knowledge, is how to use the pointer system.
The LDA o2000 will load on the V2000 memory, who is here the same V memory than the drive #1. How can I take V2000 and load it on a V3000 (Drive#2, and V4000 & V5000 drive # 3 &4;future drive)?.
I tried to use an IB-201 and IB-200 with no luck, basically I need help to find a way to copy a Vmemory to an another V memory.
One more time thanks for your time and patience.

On another rung use the always on contact SP1 to LD box v2000 and OUT box v3000 and in the future OUT v4000 and OUT v5000

I got it working, I change the LDA to O1500, and made the rung like you said Sp1 LDv1500 and out to v2000 and V3000, I'm able now to start stop the system and change the speed with the pot. Thanks for your help, you guys rock.
