8.7.3.6 DATA COPY Command
Description: This command enables the data which has been read into
the BÜP03E Receive buffer to be copied from the PLC program into the
PLC Receive buffer during the Receive process. If the BÜP03E Receive
buffer is not emptied quickly enough with this command, a data loss may
occur which is signalled back. If no new characters have arrived after the
last "Data copy", the user is informed by a fault message.
The BÜP03E Receive buffer is always copied 1:1 into the PLC Receive
buffer. The old data in the PLC Receive buffer is always overwritten by
this command.
