I've used the dnetudp communication driver to communicate with a number of 205 series PLC's and it has always worked very well. Now, I'm trying to use it with a DL06 PLC and I cannot get it to work at all. I'm using the same Windows 7 PC that I've used to communicate with the 205's. Has anyone used this for DL06 PLC's? What's the trick to get it to work? The LabVIEW error message I get is code 54:
"The network address is ill-formed. Make sure the address is in a valid format. For TCP/IP, the address can be either a machine name or an IP address in the form xxx.xxx.xxx.xxx. If this error occurs when specifying a machine name, make sure the machine name is valid. Try to ping the machine name. Check that you have a DNS server properly configured."
I'm entering the IP address as UDP::192.168.1.10. I've confirmed that I can see the PLC by pinging it on my PC and I can communicate with the PLC over the ethernet link using Directsoft.
