QUESTION

How should I access these (Enron Modbus) registers?

Asked 2021-Dec-07 at 15:02

While using an OMNI Flow computer I ran into an issue I can't really wrap my head around. I'm trying to access 32 bits IEEE floating points number using NModbus.

What I do to get one number :

Read 2 registers using ReadHoldingRegisters(byte slaveAddress, ushort StartAddress, ushort numberOfPoints) with numberOfPoints = 2.
Convert the 2 ushorts I read into 1 float like so :

...

ANSWER

After a few tests I have noticed that I am able to read the correct value from a register by using ReadHoldingRegisters(byte slaveAddress, ushort address, ushort numberOfPoints) with numberOfPoints = 2 while I get an error if I try with numberOfPoints = 1 because my device sends back 8 bytes of data instead of 4. This is coherent with the documentation stating that

You cannot read or write a partial variable

And since each floating point is in the form of a 32bits register I can't read less than 2 ushorts.

Moreover, I discovered that, for me to read a value from a specific register (be it float or boolean) I had to use an address that was decremented by 1. So for example if I wanted to read the value in register 8080, in my code I should in fact read register 8079.

I had a feeling there was an offset in the addressing but I wasn't expecting this.

I'm converting a project from NModbus4 to NModbus (since NModbus4 has last commit 5 years ago) but I can't find any modbus slave tcp implementation example so I'm stuck to this code and don't know how to get further. I'm searching for a solution all morning but

With this package I've managed to connect to Modbus RTU<->TCP converter that communicates with measuring device:

Here you have some code samples that may be helpful (Especially from line 466):

I have tested one method for reading holding registers (but as master) and it seems to be working.

QUESTION

Azure DevOps build cannot load referenced assemblies

Asked 2020-Sep-08 at 16:30

I've a .Net 4.7.6 solution with 400 projects. Some of those projects are referencing local DLL, some are using nugets packages.

Everything is building fine on our VS, everything is building fine on our build machine(with MSBuild), but once we pushed everything on Azure DevOps, we have a bunch of referenced DLL(not all) that doesn't load:

One example coming from package would be Log4Net:

What could be different regarding the loadable DLL between our VS Studio of the whole team and azure?

When we deal with local dll files on Azure devops, we need to submit the those local dll files into the repo.

And the HintPath in the project file for those local dll files should be relative path not absolute path.

Last but not least, if you push dll files through git lfs to repo, in the Get Sources step there is a specific checkbox to enable git-lfs support. Without it the file will be replaced with a placeholder to the lfs download location:

Update:

we need to submit the those local dll files into the repo. what do you mean by that? All DLL are on our git(I mean, on a brand new computer with visual studio, I can checkout the code and build, no need to install anything else). Also, we use Azure Repository, so we don't have GUI steps, and I've no Get Sources step in the template that has been generated

I mean if we use those local dll files with Azure pipeline, we need submit those dll files with our projects to the Azure devops repo. When we create a build pipeline, we will select the build source, then Azure devops pipeline will checkout the build source to the build agent:

The code source could be Azure devops repo, Github, Github Enterprise server, Bitucket cloud. If you select the Azure devops repo as code source, we need submit and push those dll files to the Azure devops repo.

Next, when you open your build pipeline (YAML), and click the three vertical dots, select the Triggers and switch to YAML tab, you will see the get source:
