Bytes 5 ... 8: Parameter value / error information
The state of the status bit 7 in the service byte determines the meaning of this data field:
Parameter value (data)
Depending on the data format, the length of the parameter value is between 1 and 4 bytes.
Data are saved in the Motorola format, i.e. first the high byte (high word), then the low
byte (low word):

Meaning of bytes 5 ... 8
0 Bytes 5 ... 8 contain the parameter value (data 1 ... 4 ).
1 Bytes 5 ... 8 contain an error message (error 1 ... 4) due to an invalid access.
Note!
Strings or data blocks cannot be transmitted.
