manjey73ParticipantWell, @Mikhail can easily see his mistake. It is enough to look at the result of the CRC calculation in the Modbus driver before it is split into bytes for the packet 🙂
manjey73Participantdid I understand correctly that when you remove frames from the mnemonic scheme, then the trend component starts working for you?
manjey73Participantyou probably made a mistake with the channel number on the trend.
manjey73ParticipantIt is allowed to link to html in another resource, for example http://10.2.0.1:8081 but in this case, the javascript of another resource may be blocked inside the frame.

manjey73Participanthttp://localhost:5000/Object_13 What do you have there? the link for the frame?
if I’m not mistaken, you need to place your pages in wwwroot\custom and the link will start with /custom/myHtmlPage.html
Do you want to download the svg directly as a link? I’m not sure that’s going to happen.
You have Images in the project tree, so you should add an image there. Or a more complicated way, use the ExtraMarkup component.
manjey73ParticipantEnter there 10 06 02 02 00 03
And then enter 10 06 02 02 00 03 F2 6A if the byte order in the CRC corresponded to the display of the VALUE in the parser
manjey73Participantthe calculation is correct, but the displayed value is incorrect, since the CRC in Modbus is always inserted the lowest byte ahead.
manjey73ParticipantCheck in the browser (show code) on the i-frame element
manjey73Participant
manjey73ParticipantIn Modbus, the lowest CRC byte always goes first, then the highest.
A feature of the CRC calculation in the Modbus protocol is that if we send a packet along with the CRC to the calculation, we should get 0
manjey73Participantframe can block scripts. But in theory, if it works within the same domain, then everything should work.
See what’s going on in debugging. Perhaps you just entered the wrong link to display in the frame.
manjey73ParticipantThe speedometer can be adjusted to suit your needs. You can replace the background image and arrows there.
manjey73ParticipantThe format should be On-OFF. The error is probably related to the fact that you need to set the byte order correctly. Or set up the address start correctly from 0 or from 1.

manjey73ParticipantIt is possible to duplicate the device. And this is the only way at the moment.
For example, you have a myDevice1 device, you create myDevice1_1 and myDevice1_2 and make different polling patterns, for example, a part for fast polling and a second for slow pollingA team survey requires formulas to work.
manjey73Participantthere you need to submit a command so that the gateway sends the data that was available during the period of absence of communication. Perhaps you can write a script on the main server to monitor and calculate the time and use the automatic control module.
