In BFM's (buffer memory) with an " * ", data
can be written from the programmable cont-
roller using the TO command.
These BFM's should always be given when the
programmable controller goes from STOP to
RUN. Buffer memory (BFM's) are reset to their
default settings upon power on.
The buffer memory also handles information
