WRITE_PRI Behavior of WRITE_ALM
0 No alarm is been generated in WRITE_ALM
1 Alarm is been generated in WRITE_ALM, but the control system won’t be notified about
it.
2 reserved for block alarms
3-7 Clearing of write protection is sent as user/operator note to the control system, according
to the specified priority (3 = low and 7 = high).
8-15 Clearing of write protection is sent as alarm to the control system, according to the
specified priority (3 = low and 7 = high).
5.1.3 Resource State Re-Initialization
The resource consists of a state machine which reflects the current state of the FF specific part of the IFC090-
FF. This state is displayed in the Resource Block parameter RS_STATE and can have the following settings:
RS_STATE Description
ONLINE This is the normal operation state. All FF links are established and the resource
works in automatic mode
INITIALIZATION Resource’s initialization state. This state will be passed if the device is connected
with the fieldbus. All FF specific parts will be initialized with respect to saved
configuration
ONLINE LINKING In this state, all parameters are initialized and the device is waiting for the links are
all established.
STANDBY This state reflects, that all initializations are made, but the Resource Block is in Out
of Service mode.
In some situations it could be necessary to restart or re-initialize some portions of the device (due to a
completely wrong configuration, etc.). To perform this, some degrees of reset/re-initialization are supported by
the Resource Block parameter RESTART. Assigning a special value to this parameter, it is possible to enforce
re initializations as described in the following table:
RESTART Description
Run Setting for normal operation.
Restart Resource Warm start of the IFC090-FF measurement electronics.
Restart with Defaults Sets all FF parameters to their factory default values.
NOTE: To be used with caution!
Restart Processor Cold start of the IFC090-FF measurement electronics and warm start of the FF
specific application.
5.2 Transducer Block Configuration
The Transducer Block as interface between the device specific measurement hardware and the Fieldbus
Foundation specified Function Block model, decouples the sensor output functions required to read the
measurement value from the Function Blocks. Therefore, the Transducer Block is also based on contained
parameters only, but provides its measurement value in a channel based scheme to the Function Blocks.
