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.

  • Thanking everybody for their help.  Things are moving along, but not there yet. 

    We are able to read properly.

    Writing is a different story.

    In using a latched write, the first 32 outputs function properly, but none after that.

    DNP is using 2 PLC bits per address, which is understood.

    What would cut the operation off at 33?

    Tried block size, Maxbits, MaxPending.

    Even went into the driver with the instructions for using the Supergenies with DNP.

    Is there something basic that we are missing?
