Title: Standalone CLX driver connection to Micro800
Post by: Wilhelm Baard on April 27, 2020, 09:03:20 AM

I remember a while back it was mentioned that communication to a Micro850 PLC should be possible with this driver if the routepath is set to nothing. I have tried this without success.Im using the below code, as leaving it blank doesnt seem to help.

In the windos forms event (load):
CLXDriver1.Routepath = Nothing

In the properties tab everything is kept on the default value except for the DisableMultiServiceRequest, which is set to true (since the Micro800 PLC's doesnt support the function) and the IP address of the PLC which is set to 192.168.0.1 to match that of the PLC. (RoutePath left blank)

The demo returns error code :Unknown Code 785 in the status strip

Any thoughts? Thanks in advance

Would you be able to do a Wireshark capture to see if the code is coming from the PLC or the driver? If it is the PLC, Wireshark may possibly have a better description of the error code.

Thanks for the quick response

I have attached some screen shots and the wireshark file (didn't even know such a tool existed, so I downloaded it quickly). From what I can gather, the PLC responds with a message that it is unable to connect.

It is trying to pass through a backplane which it should not if RoutePathis set to Nothing. What version of the driver are you using?

It should be the latest one I think (bought and downloaded over the weekend), the relase note file says v1.33
