C# Example Demo

[Michael LeTan]

I have successfully downloaded and run the C# example of the master and outstation. I can see the value change in the outstation reflecting in the master. The issue I am having, the timestamp mode and the timestamp within the master are showing "INVALID" and "1/1/1970 12:00:00 AM respectively.

Any advice would be greatly appreciated.

Thank you!

Hi Michael,

Many DNP3 variations, including all of the static ones, don't carry a timestamp.

If you produce an event that carries a timestamp, then you'll see the value become "synchronized" and have a non-epoch value.

Adam,

Thank you so much for replying! 

I have created a SimpleConsoleCommandHandler. It is very similar to the SimpleCommandHandler. In the SimpleConsoleCommandHandler, I returned CommandStatus.Success for all the implemented functions. I have placed a breakpoint in each function so I can inspect the behavior. I then added the instance to the channel.AddOutstation as seen below. When I run it, it would not stop for debugging. The snippet below, very similar to the example, I added two instances for debugging.

var outstation = channel.AddOutstation("outstation", SimpleConsoleCommandHandler.Instance, ConsoleOutstationApplication.Instance, config);

The attachments are:

• SimpleConsoleCommandHandler - simple implementation that returns CommandStatus.SUCCESS
• ConsoleOutstationApplication - something simple to test and explore.

I am unable to simulate the value with a timestamp at the same time debugging and learning.

Any guidance would be appreciated.

Thank you for your time!

Michael

Adam,

After reading through other emails, I was able to solve the double issue along with the time stamp.

On the Outstation, when adding an analog type, once I set the eventVariation and the staticVariation, both the double value and the timestamp showed up in the Master.

The snippet below illustrates what was done:

outstationStack.databaseTemplate.analog.Add(key, new AnalogConfig()

                    {
                        eventVariation = EventAnalogVariation.Group32Var7,
                        staticVariation = StaticAnalogVariation.Group30Var5
                    });

Thank you for your time!

Thanks for sharing that you got this worked out.

Going back to the example demo, I am trying to get the OctetString to show up. I have simulated updates for strings less than 200 bytes.

I have set the OctStrings in the Outstation as follow:

outstationStack.databaseTemplate.octetString.Add(key, new OctetStringConfig()

                    {

                        eventVariation = EventOctetStringVariation.Group111Var0,

                        staticVariation = StaticOctetStringVariation.Group110Var0

                    });

I would simulate them by calling the changeset.Update:

changeset.Update(value, dataType.Key);

When getting it from the Master, I do not see any updates from the OctStrings.

Not sure what I am doing wrong. I am doing the same steps as the Binary and for the Analog. Please advise.

Thank you!

Michael,

Just letting you know I haven't had a chance to try out the C# examples yet with octet strings.
