For every READ and WRITE the CP generates PLC header for request
and acknowledgment messages. Normally the length of these headers is
16Bytes and have the following structure:

Note!
Please regard that in opposite to Siemens-S5 systems, the block
addressing of these CPUs takes the start address as byte number and the
length as number of words.
The following messages can be returned via
error no.
:
Error no. Message
