Configuration restoration confusion

Digi One IA/IAP
1

I pulled a brand new Digi One IAP from the box and loaded the following config file (file_1.cfg).

No messages were added to the status log. I then rebooted the unit and tried to establish a Modbus/TCP connection–no dice.

I then saved the configuration (file_2.cfg) to diff against the file I loaded. Check the “set ia master=1 active=on protocol=modbustcp transport=tcp ipport=502
table=1” line!

OK, maybe I did something wrong. I restored the unit to factory defaults and loaded the original config (file_1.cfg) once more, followed by a save (file_3.cfg). The modbus routing table is still incorrect. I don’t know why file_1.cfg refers to table 2 with no table 1 present, but I suspect that’s part of the problem.

Did I do something wrong? Or is this maybe a latent bug in the configuration file handling?

This could be a latent bug - the next firmware (“F” is in final testing) has moved the “set ia table” section up to before the serial & master. This change was done by an engineer trying to clean up some quirks in the Web UI related to tables, so he may or may not have seen the issue you noticed.

I’d guess the “table=2” was rejected during reload as that table didn’t exist (yet), but table=1 does at that point (ie: a dummy Modbus-compatible table was created for the serial slave, which defaulted to table=1).

Asside from the bug here, manually editing & moving the “set ia table” section above serial & master would solve the problem keeping the table being =2; as would renumbering your table to be 1 instead of 2.

Do I need to do anything with this and the serial stat bug I’ve noticed, or is it too late?

Makes sense to me.

Manual edit worked. It’s talking now.
