I am trying to add functionality to my communication (as the master) with inverters (the slaves) via a corporate Modbus implementation (from SMA Solar Technologies), without actually connecting to the hardware all the time. Id hoped, that this tool might ease things for me.

However so far, I could not even get it to run with itself.
I thought I tried the simpliest queries I already managed to implement in my own communication.
Reading Input Registers with FunctionCode 0x04 at Register 30843. Unsigned32 (2 Registers) at SlaveID 3 and of course ProtocolID 0.

But all I got is a TimeoutException (see screenshot below).
Is there anything I could check or read up on to figure out where things went wrong?

PS: I am running a Debian Bookworm system with OpenJDK 17.0.5+8-2 using Hotspot JIT. Maybe I should mention, that if I am running the .jar without sudo and trying to connect to 127.0.0.1 it says java.net.ConnecException: Connection Refused.

It would be great if we had low baud rates such as 110 and 300 to test long distance connections.

Dont know, if this is still actively maintained, but as I was having trouble using the GUI itself (#12) noticed the limited data value types.
I was wondering if it would be possible to implement other data value types, for example such as signed16/32/64?

Not sure how interesting this would be, but I myself would use the Functioncode 0x17 and (0x10) as well.
However I understand, that there might be several other codes with higher priority.

Thanks for this tool which is really helpful in simulating and explaining Modbus communication, in my case for configuring filters in OT-firewalls.

For illustration purposes, it would come in handy to also have the possibility to write a single register directly (0x06).

As I don't know about all the dependencies inside your project, I don't want to fork this right away. But if you can tell me about the positions where this might have an impact, I can write these few Java lines by myself as well.

(btw. I'll fix the German translation as well then)

This is a great software, I've been using it for educational purposes. The slave simulator function is really handy, however as a "standalone" slave simulator I found an issue with Modbus Mechanic. It seems that when running it as a slave simulator towards other Modbus Master (software) the slave simulator GUI does not refresh its status on coils and holding registers when receiving write requests from Master. I'm not sure if this mode of operation is the original intension of this slave simulator, although it would be a great feature to be able to simulate slave devices across a network.

(It's running on Windows 10 and Modbus TCP).

It works fine along with the Modbus Master in Modbus Mechanic, however.

Describe the bug

I do not know to what serial device to connect when using slave simulator and end up with an exception when sending a payload.

To Reproduce
Steps to reproduce the behavior:

Start slave simulator RTU, it is not know what virtual device comes up that can be connected to.

It is not known on what serial port the slave simulator is running. when simply setting rtu and sending a modbus payload i get an exception:

Can you clarify to what serial port i have to connect or is this a bug?

Thanks a lot and sorry if i simply dont get it.

regards

Michael

First of all: Thank you very much for sharing this useful software!
It helps a lot developing some Modbus Master and Slave Devices (ESP32+Max487 Hardware with eModbus Library as Master and Attiny85+Max487 as Slave with tinnymodbus Software).
I mainly use Modbus RTU on a Linux Machine and it is a great tool to analyze and test modbus traffic.

I just wanted to know if the Modbus Slave Simulation should work with RTU too? (i have tested it successfully with Modbus TCP when running as root).
eg. i have a Modbus RTU Master which regularly polls some registers and i want ModbusMechanic to answer to this polls. (aka act as a virtual Sensor)
Dont know if this is not Implemented, a bug or a User Error from my side :)

Also when i open the Serial Monitor, i do not see any Traffic, and cannot send Packets any more ("cannot open serial port ttyUSB0") until i close the Serial Monitor Window again..

$java -version                                                                                                                                                                                                ✔

Describe the bug
It would be great to add some information or try to handle the case when a user is not in dialout group.

To Reproduce
Steps to reproduce the behavior:

1. check that you are not in dialout group: $ groups
2. $ java -jar ModbusMechanic.jar -debug
3. Tools-> RTU Scanner, click 'Scan'
4. See error in console:
   purejavacomm.PortInUseException: errno() == 13

   at purejavacomm.CommPortIdentifier.open(CommPortIdentifier.java:159)
   at modbusmechanic.RTUScannerThread.run(RTUScannerThread.java:49)

Expected behavior
To fix that you need to do: sudo usermod -a -G dialout $USER

There are no any errors on UI.

I have a USB modbus stick that places the tty file in /dev/serial. When I select RTU and want to select the correct serial port, I only get to chose from the ones listed under /dev/, so my USB dongle is not detected.

When using my USB dongle with it's file under /dev/serial in Domoticz, it has no problems being recognised.

Good morning,
can I use this app to simulate a master modbus tcp? if yes how?

Kind regards

Francesco

I was trying to see if my FunctionCode 0x06 works alright, but realised that the implementation in Modbusmechanic v2.5 seems to be a little bit faulty?

When I setup the simulator as Holding Register 50000 (UINT16), no swaps, I am not able to overwrite this value with FnC 0x06 correctly. No matter what I want to write, it always defaults to 0. Attached youl find screenshots of the WireShark capture of different write requests, always with the same data value.

ModbusMechanic client with 0x06 request and value=5.

WireShark Output for my own implementation, same settings.

ModbusMechanic client with 0x10 request and value=5 seems to work okay...

... but as far as I understand simply writing one register (u16) should be possible with 0x06 as well?

Sorry in advance, if I missed something.
EDIT: My understandings in this are based on "MODBUS APPLICATION PROTOCOL SPECIFICATION
V1.1b3" from Modbus.org but might be oudated.

In the register scanner when you select the 'Hide Zero Value Registers' option not only Zero value registers are hidden but also some registers where the value is negative. See attached screenshots, the Float with negative values are hidden.

Hi,

i just want to inform, it's working on linux.
linux mint 19.3 Cinnamon.

some enhancements can be made, such as listing only active serial (ttyS* is all listed).

thank you for the software.

While using the register scanner I noticed that values I expected would jump around between the registers on almost every scan.

To Reproduce
Open up the register scanner and scan a node using tcp and note a value.
Scan again and then note that the value you are looking for moved to a new registery
