Advantech Wise4012e Modbus Simulation

Application which simulates an Advantech Wise 4012e IO module. The application is written in .Net Core.

Purpose

It runs a Modbus service at [127.0.0.1] (configurable):

Switch 1 on Discrete coil 1 (read/write) 0 or 1
Switch 2 on Discrete coil 2 (read/write) 0 or 1
Relay 1 on Discrete coil 17 (read/write) 0 or 1
Relay 2 on Discrete coil 18 (read/write) 0 or 1
Knob 1 on Holding Register 40001 (read/write) 0 - 4500
Knob 2 on Holding Register 40002 (read/write) 0 - 4500

Usage

This is a .Net Core application.

Select a local folder (eg. c:\dev) in which the project will be put for execution. (please select a short path to prevent a path with has too many characters).

In Github clone the code or extract is as a ZIP file.

Compile and run this application in Visual studio Code.

Execute the following steps:

Install .Net Core SDK.
Open the folder of the project in VS Code. Select 'program.cs'. Accept any suggestions regarding debugger and packages.
Compile the application

Note: the Debug Console is read-only. We will need to run the app outside VS Code.
Go to \bin\Debug\netcoreapp2.0 folder of the project. Here you will find the \bin\Debug\netcoreapp2.0\Advantech.Wise4012e.Modbus.SimulationApp.dll

Note: Do not expect an executable.
run the dll on the command line using the command 'dotnet Advantech.Wise4012e.Modbus.SimulationApp.dll'.

You can now read and write Modbus using this simulation in Modbus clients like CAS Modbus Scanner or Azure IoT Edge.

IoT Edge Microsoft Modbus Module

It is confirmed this simulation can be used together with the Microsoft Azure IoT Edge Modbus Module

To get it working:

Go to 'settings.json' and replace the localhost address by your specific local IP Address (you can look it up using 'ipconfig')
Start the app as described above
Confirm changes to the firewall for this app and port
Use this IP address in the Module Twin of the Modbus module

The configuration of the device twin will look like:

Alter the behaviour of your simulation

When running the application, you can alter the values of the simulation.

Just enter:

1 0 (switch 1 to false)
1 1 (switch 1 to true)
2 0 (switch 2 to false)
2 1 (switch 2 to true)
17 0 (relay 1 to false)
17 1 (relay 1 to true)
18 0 (relay 2 to false)
18 1 (relay 2 to true)
40001 0-4500 (pick a value between 0 and 4500)
40002 0-4500 (pick a value between 0 and 4500)

Note: The relays can not be changed

NModbus4 library

This simulation is making use of the Nuget package NModbus4. Great work!

advantech.wise4012e.modbus.simulation's Issues

Issue connecting Emulator

Hi Sander, @sandervandevelde
When I start the emulator it looks to be running.
Start Advantech Wise4012e Modbus simulation at 127.0.0.1
Slave 1 supports switch 1, switch 2, relay 17, relay 18, knob 40001, knob 40002

False False False False 0000 0000 - Write '1 [bit]' '2 [bit]' '17 [bit]' '18 [bit]' '40001 [int]' '40002 [int]' or Q to exit
1 1
True False False False 0000 0000 - Write '1 [bit]' '2 [bit]' '17 [bit]' '18 [bit]' '40001 [int]' '40002 [int]' or Q to exit
1 0
False False False False 0000 0000 - Write '1 [bit]' '2 [bit]' '17 [bit]' '18 [bit]' '40001 [int]' '40002 [int]' or Q to exit

True False False False 0000 0000 - Write '1 [bit]' '2 [bit]' '17 [bit]' '18 [bit]' '40001 [int]' '40002 [int]' or Q to exit

But the IoT client cannot connect.. Please advise :) Thanks!

Local IP

Hi
The instruction Go to 'settings.json' and replace the localhost address by your specific local IP Address (you can look it up using 'ipconfig') suggests that you can only interact with this module if it is installed on the IoT edge device (local IP) or in same network?
