The table is shown for static CB-switching without acknowledgement (S41 = 0).

Source for w
E
at S85 = 0, 1, (4, 5 as of software version -A5) is w
EA
or at S85 = 2, 3 w
ES
(SES). The external setpoint
fed in through the SES (w
ES
) is tracked. Tracking is not possible when the external setpoint is fed in via w
EA
.
3)
SH can only be reached after w
E
, if Int = 0 and CB goes from 1
→
0 (computer failure). If CB = 0 and Int is switched
from 1
→
0, wi is still active. Since SH is not tracked, switching over to SH can take place with the setpoint ramp tS.
4)
By OR-linking with the digital outputs H, N and the control signal Si no computer standby or computer operation can be
signaled in manual-, tracking- or safety operation.
