You don’t have a system tray that shows the clock, keyboard layout, network status, mixer status, battery, and so on.
You only have the Task Bar work area- This reply was modified 5 years, 9 months ago by manjey73.
manjey73ParticipantRun Setup again, there will be a choice of installation or removal.
manjey73ParticipantThe Server and Communicator are started in minimized mode, locate from the system tray
manjey73ParticipantHope just for those who have devices with m-Bus. At least it is planned to make free drivers that work with a specific device on the logs of requests and responses of the device. It is not difficult, as little changes there.
manjey73ParticipantThere is also a problem with scanning devices, not all manufacturers lay this functionality. For example, Wesser Heat Meter does not have this functionality and does not even have an address provided by the Protocol. It has only ID and only it can be used to run a survey.
manjey73ParticipantSorry for my English, I use online translator
Thanks for the links. But the problem I have is not with the description of the Protocol, and with real data from the devices. The Protocol gives a greater freedom of choice of data transmission, which of them will choose the manufacturer only knows. I would like to see different types of data transmission from different manufacturers. At the moment I have only two devices and both transmit Variable data Structure.
At the moment I have implemented the processing of Variable Data Structure in the response.

So it became clear that any online calculator Modbus CRC in the calculation of CRC along with it should give the result 0
It was necessary to buy such a module, there is a description in English and you can check the information on the Protocol and the method of calculation of channels.

manjey73ParticipantWrite to the Chinese that they have the wrong byte sequence in the CRC. Well, if it does not help, you can try to build KpModbus.dll in the new version, where you change the sequence of bytes for CRC, and to call it KpErrorModbus.dll 🙂
manjey73ParticipantProbably your device is not quite standard. If you use the specified link and check your request, the CRC is correct, the lower byte forward, according to the Modbus Protocol.

Online Calc shows just the CRC value as it is.
I would like to look at this device that does not send CRC Modbus younger byte forward, I have never seen this in the factory products.

manjey73ParticipantThe link at the bottom has links to but in Chinese. There will be question marks instead of characters
manjey73ParticipantCheck if this Board has a WEB interface ?
manjey73ParticipantThe description indicates that the relay must be sent ON1 to be switched on. I can assume that this is the name of the button but the screens Chinese characters. Write to the sellers of this Board, or follow the links, maybe they have this program in English. If I’m right, then put this program you can use the tracking programs and see what are the parcels in the Protocol.
The Chinese may be deceiving, saying that there Modbus TCP. I was afraid to buy a Board without a description in my time. I chose the one where the list of registers for management was given.

manjey73ParticipantGiven the Ethernet module used, it can be assumed that there is no Modbus TCP but Modbus RTU on top of TCP. It is a relay not come across live.
manjey73ParticipantGive a link to the device you purchased on AliExpress
When connecting via RTU, you are informed that the address does not match
manjey73ParticipantWhat exactly do you use from the Chinese site ?
On AliExpress was not a description of the registers ? -
