7.4 Status code of the measured value
The following status codes (decimal values) are used by the Type 3785 Positioner:
BAD:
0 =
non-specific – value bad without more details.
4 =
Configuration Error – device settings not consistent.
12 =
Device Failure - device error.
16/17/18/19 = Sensor Failure – error in determining the measuring value (limits exceeded).
Limit bits indicate that the measured value limits were exceeded.
20 =
No Communication, with last usable value – (internal) transmission error, device
operates with the last usable value.
24 =
No Communication, with no usable value - (internal) transmission error, device
does not have an usable value.
28 =
Out of Service – no valid value since the block is out of service.
Uncertain:
64 =
Non-specific – value uncertain without more details.
68 =
Last Usable Value – value uncertain, device operates with the last usable value.
76 =
Initial Value – starting value (default).
Good (non-cascade):
128 = O.K. - value is o.k.
160 = Initiate Fail Safe(IFS) – if the reference variable has this status and is not transferred in
a period longer than the FSAVE_TIME, the action configured in FSAVE_TYPE
is executed.
Limit bits:
The two bits of the measuring value status with the least significant bit are used to indicate
that the limit values have been exceeded.
Bit 0 =
Low limited – lower limit value exceeded.
Bit 1 =
High limited – upper limit value exceeded.
Bit 0 and 1 = Constant (high and low limited) – value is blocked.
