Byte number (BCD format) ++)
In compact terminal blocks, it is not possible to enter the individually
defective module in the error fine coding (the terminal block always fails as a
complete unit); i.e. the first defective byte (the byte with the lowest address)
found in the image is always the one given in the error fine coding. If the
terminals are mixed (inputs and outputs), this is always an input byte.
