Signal priorities
21.3.1
When several statuses overlap for one valve
For the classic variants
(24 V DC, 120 V AC, AS-i, DeviceNet)
and
the “Device-specific display mode
8681 Classic X”
of the IO-Link and büS/CANopen variants, the the following priority list applies:
1.
I
nternal error
2. Manual operating mode
is active, e.g. by magnetic manual override - see chapter “22 Service Mode /
3. Other faults,
e.g. position measuring system (WMS) not taught, WMS signal error, bus error or other
(see chapter “21.2.2 Feedback in case of errors / warnings” on page
)
4. Service / maintenance request
For the other display modes of IO-Link and büS/CANopen design:
(see chapter “21.1” on page
) the display logic is described in detail in the respective subchapters:
• “NAMUR” – see chapter “21.1.2” on page
• “Valve mode” – see chapter “21.1.3” on page
• “Valve mode + errors” – see chapter “21.1.4” on page
• “Valve mode + warnings” – see chapter “21.1.5” on page
21.3.2
When position feedback overlaps
The following logic is the
factory setting
for all display modes which report the position:
S1
S2
S3
S4
Error Priority
Note / flashing patterns
active active active
active
S4
Flashing in S4 flashing pattern (if S4 activated by
DIP
*)
) as S3/S4 has priority over S1 and S2
active
active
S4
Flashing in S4 flashing pattern if S4 activated by DIP
*)
active active
active
S3
Flashing in S3 flashing pattern as S3/S4 has priority
over S1 and S2
active
active
S2
Position feedback of S2 has priority
Table 17:
Display priorities when position feedback overlaps (factory settings = „PRIO 24“)
*)
The activation of S4 via DIP switches is possible only with the classical designs and with the büS/
CANopen design.
The IO-Link design has no DIP switches, S4 (external initiator signal) can be activated/deactivated only
via configuration/parametrisation.
Factory settings:
S4 has the highest priority, descending to S1 (i.e. S4 - S3 - S2 - S1) - this corresponds to
the “PRIO 24” in the following “Table 18”
.
If the factory setting described above in
“Table 17” (= “PRIO 24”) is to be changed, this can be done
for
IO-Link and büS/CANopen designs
via software using the sensor parameter “PRIO (priority feedback
positions)” (0x2C05 / 0x8).
