Data Logging
本帖最后由 terefere 于 2022-10-4 05:22 编辑I think about event table screen who show system error. Is possible to update table when I display other screen or event wgo I get in this time must be omitted?.
You can use a USB to TTL module, connect it to the J4 connector on the back of the screen, and use the computer serial port debugging assistant to view the running log of the screen. You can take a picture of the back of the screen. 本帖最后由 terefere 于 2022-10-9 06:10 编辑
No, No. I mean about this option. [doc.gz-dc.com/Control/13_record.html It look's like I can write to table only in time when this screen is active?.
BTW About J4. Some time ago I find that in upper row, at second pin from right you have debugger message ;) In occasion, is possible to catch DBG message string and show it at user application level?.
And I back to J4 again. Is possible to program device by this connector if I modbus port is occupied?. Burn firmware by SD card is a bit tiring at firmware create time.
