Issue 1.5 24 March 2006 Page 8-9
DP r Perform a “diagnostic poll” on responder r. This command initiates a
diagnostic poll, similar to that described in section
8.1.6.4. The results are
displayed automatically on the MXP but not the MX4428. To see the results
on the MX4428 use the DR command.
DR r Display the results from the last DP command on responder r. (Use this
command at least 30 seconds after a DP command.)
GH r Reset history of all points on responder r.
GT r Reset tracked values (clean air values) of all points on responder r.
RH r p Reset history of point p on responder r.
RT r p Reset tracked value (clean air value) of point p on responder r.
The above commands are described in more detail in the F4000 Programming manual.
The remaining commands on the DA menu may display returned values from the MXP, but
have no direct affect on the MXP.
