In the status byte an error code is returned, if necessary. In the case of an
error-free transmission, a 0x00 is returned in the status byte.
The control byte contains the information regarding which data block
element of a parameter is accessed. Bit 2 controls the transmission of
sequential telegrams (writing lists in several steps).
In this byte the device address set at in the
P-0-4022, Drive address of
serial interface
parameter has to be entered.
In the useful data bytes it is possible to enter any value that is interpreted
in a different way according to the service. For flash programming, for
example, binary characters are entered in the useful data and when
writing a parameter the decimal numeric value is entered.
The number of bytes in the useful data field and of the useful data header
are entered in the DatL and DatLW bytes.
Status Byte Description
