Baumer NE215 Operating Instructions Manual
Open interface description
Important
The blanks between the particular characters of the commands
only serve the purpose of better legibility. The input at the PC must
be effected without blanks. Control characters (less than 20Hex) are
set in „pointed" brackets. If a false protocol has been sent by the
PC, the counter will return an error message. Please read the
paragraph regarding error messages on page 29 under 7.7 .
7.3
Reading of storage location
All storage locations that are indexed with a line number in the
programming scheme (except the separating lines that are indexed
dashes) can be read out. The protocol: <STX> Address line <ETX>
[<CR>] can be used for each line. The return answer of the counter
may vary in the protocol length from one line to the other. This
depends on the data length of the individual storage locations.
The counter can also be read out if operated in the RUN mode as
well as in the PGM mode. The only difference is that the return
answer of the counter will contain an „R" or a „P" in the mode
parameter, as described in the following.
