Geez, what a headache. But I got it to work properly. Was able to establish communication via Lab View HMI to a Direct Logic DL230 PLC using the DS Data OPC server (DS data server is included with the direct logic install). For example, I bound six toggle switches (Must be read/write) through the OPC server and to the PLC. The problem I was having at first was simple; I didn't put an END statement in a blank PLC program and I didn't enable the OPC server. So I just made another toggle switch and bound that to the enable bit. Made it true and BOOM it worked. If anyone wants to do the same thing you can message me and I will be more than happy to assist you.

Thanks Yen! I think I found out my problem. I do not have an OPC lookout driver installed when I try binding the controls of the PLC with IA OPC Server 5.1--sometimes not having the right stuff can be a headache. Not to mention, being able to obtain the stuff you need without breaking the bank. Anywho, I did notice an DsOPC server that comes with my Direct Logic software that I was able to bind with some toggle switches, so I might just take this route instead because the OPC client is easier to obtain. It appears the server is communicating with Labview, but not with the PLC. I guess there are usually 4 parts to this type of system, and don't quote me on this, in order for the system to work. The application; the OPC server; the OPC client and, of course, the PLC or whatever. I think I only have 3 parts....Yes this will end up driving me insane before you know it, but I have learned a lot. I just hope I learn it completely.

Hi, Wondering if anyone has an OPC lookout driver for Labview that they can send me. For some reason, I cannot bind my data socket (or path) to my PLC outputs due to the lookout driver not being installed for some strange reason. I have looked on ni.com for a driver, but with no success. I believe this is the only thing at the time holding me back. Furthermore, my Measurement and automation does not show any interfaces on the left hand column. Not sure what is going on, but it's kind of funky. I would appreciate any help. Thanks.

Yen, thanks. Now that you gave me that remember. Duh, 1 for the PLC addy. Thanks, again.....That takes care of part of my problem. Now I need to establish communication through Labview to my PLC. Like Data binding and data socket in Labview so Labview recognizes the path to the PLC.........New territory for me. If you remember that would be a huge push. Thanks, rolf I appreciate your input. But I want to keep it simple. Although I have taken an in depth course of Labview, I'm not quite getting what you are saying, sadly. Anyway, I have downloaded your file and will eventually take a look at it, but it's not what I am looking for at the time. Jim

Hi, My project requires an OPC server to communicate with a Direct Logic PLC (DL230). I am unable to locate any tutorials on how to do this. I have all the required programs.....Measurement and Automation, Industrial and Automation OPC server 5.1 and Labview 8.5. Basically I am looking just to control outputs on the PLC with toggle switches; just something easy for now. Any insight would be appreciated. Thank you! My email address is genroymad@yahoo.com
