Error "6." after connecting board to SupraMaticE2 #3

Closed riogrande75 closed 3 years ago

riogrande75 commented 3 years ago

I recently built this project and I am pretty confident, that everything was soldered together and programmed correctly. Right now, a UAP1 and a button is connected to my SupraMaticE2 - this works so far. As soon as I replace the UAP1 with the board from this project, I get following output on my MQTT server:

[2021-05-11 16:39:46.695584] garage_links/cover/state stopped
[2021-05-11 16:39:46.695644] garage_links/sensor/garage/status offline

Unfortunately it does not respony to any of my issued commands:

[2021-05-11 16:41:12.825838] garage_links/sensor/garage/set CLOSE
[2021-05-11 16:41:18.133533] garage_links/sensor/garage/set TOGGLE
[2021-05-11 16:41:59.022011] garage_links/sensor/garage/set OPEN
[2021-05-11 16:42:01.973374] garage_links/sensor/garage/set OPEN

If I want to open close the door manually with the button, I just get fault "6." in the display. This points to a fault on the / open "Schlupftür". But I do not have a "Schlupftür" installed at all and the RJ25 plug with the shorting wire in X30 is placed correctly. As soon as I put UAP1 back in place everything works fine again. Connecting RPi with RS485 and running https://github.com/raintonr/hormann-hcp works too, so I guess the door and control unit are ok.

Any idea from the specialists on how I could debug here?

My guess: A wrong, missing or twisted part is messing up the hoermann bus.

To narrow down the problem:

  1. The manual for my Supramatic E3 says error 6 means "Systemfehler" (system error) which would make more sense.
  2. When you have disconneted all slaves (UAP1, this board, raintor's interface) the drive shows error "7". Right?
  3. garage_links/cover/state stopped is the default state if no communication with the drive could have been achived.
  4. garage_links/sensor/garage/status offline is the default state if no BME is connected.

The next steps i would perform:

  1. Check the board's supply voltages. Are 24V, 5V and 3.3V fine?
  2. Check the RS485 lines with an oscilloscope. Can you see the master messages or is it just a flat line?
  3. Check the board parts on the RS485 side (IC4, T1, T2, T3, T4 + surrounding parts). My guess is that one or more parts have wrong values or are mounted twisted.

Ok, finally found time to work on this issue again. Factory resetting my SupraMatic E2 solved the error 6 problem easily. BUT: I dunno why I was reading over it so many times: This project is for SupramaticE3 and not my E2 - so it will not work anyway. :-(
