DNP Driver

Michael

Using the serial DNP3 driver, but can't get it to commuicate.  Serial cable and port work fine on RTU, and PLC program is trusted.

I'm pretty sure that the issue is in the setup.  The Address is suspect - the help file talks of a device number and the section of the .ini file where the address is?  I must be missing something here.

I see a key name in the client, which seems not to have a place in Citect.  Is that correct?

Any other tips and tricks for this?  I haven't seen a white paper.  The driver help looks like it was for a  few versions ago.

  • I believe the device address should be ## NAME where ## is your DNP remote's address and NAME is a name for a section in your INI where you can put device specific DNPR settings. There can also be a DNPR section in the INI for the protocol wide settings. Making the DNPR work is very tricky. The driver help section lists all the possible variables and whether it can be for driver, port or device level. I would leave most at default and maybe update you event polling times, SCADA master address and maybe timeout

    I'd suggest trying to determine where and what DNP messages is coming out of Citect. Do you have any type of protocol analyzer or does your field device have any comms logging? How about Tx/RX lights on the remote?

    I have done several DNPR projects in the past, so if you still have issues and want to post device settings and INI settings I can take a look and compare with my projects.
