Reading from the information registers
The EXDUL module provides several
16-byte wide information areas which
hold module information such as
serial number or Hardware identifier.
Additionally, the user can also read out
the writable user registers.
Information: All of the information areas can only be read as a whole
16-byte block.
Example: Read information area UserA (User string = „EXDUL-581")
An 8-byte block is transmitted and a 20-byte block is received with content from UserA or
UserB
