Страница: 44 / 78

7.4 Status code of the measured value
The following status codes are used by the Type 3785 Positioner:
Bad : Valid value
Substatus Condition Value (decimal)
configuration Error Error in device configuration, value cannot be measured 4
device Failure Device error: memory, electronics 12
sensor Failure Error in travel measurement,
limit bits indicate that measured value limits were
exceeded *)
16 / 17 /
18 / 19
no Communication, (last usable value) Internal communication error, no last usable value
available
20
no Communication (no usable value) Internal communication error, no last usable value
available
24
out of Service Transducer block in operating mode OUT OF SERVICE
(e.g. device not initialized)
28
*) Limit bits:
The two least significant bits of the measured value status are used to indicate that the measured value was exceeded.
Bit 0 = Low limited – Limit value not reached.
Bit 1 = High limited – Limit value exceeded.
Bit 0 and 1 = Constant (high and low limited) – Value is blocked.
Uncertain: Valid value, but not derived from process
Substatus Condition Value
non-specific Initialization or zero adjustment running 64
initial value Initial value during start-up (temporary) 76
