1)
The table is shown for static CB-switching without acknowledgement (S41 = 0).
2)
Source for w
E
at S85 = 0, 1, (4, 5 as of software version -A5), is w
EA
, which is assigned by S17 or at S85 = 2, 3 w
ES
,
which is fed in via the SES.
3)
Tracking only takes place at S45=0 and only w
ES
and wi to the active setpoint. When feeding in via w
EA
the feeding
instrument must be tracked.
4)
Only to be used as a flag pointer when no analog feedback is possible from the fed instrument.
5)
RC = no K-setpoint generator operation, wi not adjustable.

7)
wired-or-connection of Int = RB and CB supplies Int∨CB
No S-setpoint optentiometer operation, Δw-keys not active
(n) tracked to the value active before switching, therefore bumpless switching
