8A good active advisory alarm high limited X X X X
89 good active advisory alarm low limited X X X X
84 good active update event O.K. X X X X

Note
The status conditions have decreasing priority from top to bottom. If several status conditions
are fulfilled, the current status with the highest priority will be signaled.
B.6 Output Data (from Master to Slave)
The output data consist per totalizer (net, forwards and reverse) of one byte of which only the
two LSBs respectively are evaluated. All other bits are not evaluated but should be set to 0 for
safety. This value represents the "SET_TOT" parameter of the "Totalizer Function Block" defined
in the PROFIBUS-PA profile.
Table B-7 Totalizer mode "SET_TOT"
Bit
1 Bit
0 Profile description Meaning
0 0 cancel totalizer is running
0 1 reset totalizer is stopped and reset to 0
1 0 preset Totalizer is stopped and reset to a preset value (PRE‐
SET_TOT parameter, only acyclic access)
The transferred value is effective until it is changed, i.e. after the value 1 (reset totalizer) is sent,
for example, the totalizer will remain on the value 0 until the SET_TOT parameter is changed
again.
Each SET_TOT value affects the corresponding totalizer independently of the others. The
quantities are also cumulated independently of each other, i.e. the net quantity does not have
to be equal to the sum of the quantity forwards and quantity reverse especially if a totalizer has
been reset or was preset.
B.7 Diagnostics
The diagnostic data can be requested with the "Slave_Diag" service.
