IFC090-FF Block Description
Description
Manufacturer identification number. For KROHNE devices this is always
00012C
= 300
= KROHNE
16
10
Maximum number of unconfirmed notifies messages possible.
see also: LIM_NOTIFY
Available configuration memory in the empty resource.
NOTE:
This parameter is not supported by IFC090.
Time duration of the shortest cycle interval of which the IFC090 is capable. Within this
cycle all Function Blocks (1 Analog Input + 2 Integrators) have to be executed for one
time.
Display of the current (actual), desired (target), possible (permitted) and normal modes
of the Resource Block. By writing a permitted value to the target field, you can control
the execution modes of the block. The following block modes are allowed for the
IFC090-FF Resource Block:
Automatic Mode (AUTO)
In this mode, the complete resource is able to execute. All other blocks
(Transducer, Analog Input, Integrator) can switch to a mode different from Out of
Service)
Out of Service (OOS)
In this mode, the complete resource stops its execution. For the other blocks
it is not possible to switch to AUTO mode, unless the Resource Block does.
NOTE:
Under certain conditions (e.g. RS_STATE = ONLINE_LINKING) the Resource Block is
not capable of switching to AUTO mode.
see also: RS_STATE
Minimum time interval between two cycles of writing non-volatile parameters OUT, PV
and FIELD_VAL. Since these values are not saved, this value is always zero (0) which
means don't save these parameters.
Allows a manual restart to be initiated. Several degrees of restart are possible:
RUN
RESTART RESOURCE
RESTART WITH DEFAULTS
RESTART PROCESSOR
State of the function block application state machine. The following states are possible:
ONLINE
Normal operation state: All defined links are established.
INITIALIZATION
Initialization state: All alarms will be confirmed and
acknowledged.
ONLINE-LINKING Link evaluation state: Wait until all links are established
STANDBY
Out of Service state: Entered if mode of Resource Block is
OOS.
Allows the Fault State conditions for output function blocks to be manually initiated by
setting to 'Set'.
NOTE:
Since the IFC090-FF doesn't have an output block, this parameter is not supported.
Time duration for the monitoring-cycle in which a function block in mode RCAS has to
answer on control system requests.
NOTE:
Since the IFC090-FF has no function block capable of switching to mode RCas, this
parameter is not supported.
Setting for normal operation.
Warm start of the IFC090-FF.
Sets all FF parameters to their default values.
To be used with caution!
Cold start of IFC090 measurement electronics
and warm start of FF process.
