. Why do I get the error "Missing value" when reading some M-Bus devices? (FAQ #101762) When reading values from some specific M-Bus devices with the M-Bus modules PCD2/3.F27xx, the M-Bus driver may show the error "Missing value" even though all values are correctly returned by the device. Symptom When using the M-Bus modules PCD2/3.F27xx (with the framing protocol), the M-Bus driver may display the error "Missing value" even though all values are correctly returned. The problem concerns only few devices

protocol for PCD2/3.F2xx(x) e.g. used by the M-Bus library 2.6.100 and later The single function codes (second line of the CSF call, "0" in the screenshot above) of the relevant libraries can be found
The serial number of the S-Bus, M-Bus or Modbus one-phase and three-phase energy meter is printed on the front of the energy meter and it's also possible to read out the serial number over the communication interface. Until June 2013 the two serial numbers were different one from the other, but each one was unique.
