I can’t tell you who is changing the port, but the server, when sending to port 502, expects it to return to port 502.
copy the contents of the response from wireshark to modbus parser from the data block and find out. if there is an adequate response, then configure the firewall.
However, this will require advanced Mimic components (paid), specifically ExtraMarkup from the components.
You can create a circuit in the new Mimic editor and make the sound play cyclically while the page is open.
Yes, if the address requires 0 for the device, this may be the reason. Another option is to send a broadcast address to the device – 254 or 255 in Modbus mode when it is connected to TCP. Such things should be specified in the device documentation.
And start with one register, specifying in the settings to start with 0 or 1. Do you also have the exact device address = 1 ? Depending on the device, the device ID may be ignored in Modbus TCP mode, or it may have to correspond to some value.
show the log of a specific device. what data goes into it. is the device responding or just a timeout error?
show the line and device settings.
If you don’t see any bytes transmitted from the device in the log, then there is a problem with the connection.
As far as I know, no. I made a mnemonic specifically for the vertical version of a mobile device and created a second user specifically so that they could connect from a mobile device. Then he scored 🙂
– Will you have yesterday’s soup?
– Yes, of course.
– Then come back tomorrow. 🙂In order to write into the future, this future probably needs to be created. You can’t do this with scripts like that. It also doesn’t seem to be possible to read database data using scripts. But is it possible to rewrite the channel data all the time so that these values will be relevant tomorrow?
