M-Bus via IR on ABB B23 111-101?
I need to communicate with an ABB B23 111-101 Energy Meter via the IR-interface located on the left side of the housing.
This is done via a 3rd party IR Write/Read-head. From what I can see no communication can be established to the meter.
I am sending in a REQ_UD2-telegram, however no answer is provided at all. No blinking of the IR-LED of the meter.
What I am sending in is:
0x10, 0x5B, 0x09, 0x64, 0x16
0x10 = Start
0x5B = REQ_UD2
0x09 = Adress
0x64 = Checksum (=0x5b + 0x09)
0x16 = End
Baud-Rate & address were set on the meter to 2400 Bd and address 9, the password is left "open".
Is there any wake-up signal required? The user-manual ([LINK NOT ALLOWED]) does not mention anything on that topic so I "guess" it is not required.
Any idea of what may be going wrong here? The IR Wr/Rd-head is active and can communicate with other components like ACE3100 smart meters.
Thanks and best regards
