IFC090-FF Block Description
Access Description
Display of process alarms. The current alarm is displayed in the current field
R
an can have the following values:
Discrete Alarm
HiHi Alarm
Hi Alarm
Lo Alarm
LoLo Alarm
Block Alarm
The additional fields unacknowledged and unreported give respective
information about the current alarm state. The field disabled, which is the
only writable field of this parameter, can be used to disable these alarms.
see also: ACK_OPTION
ALERT_KEY parameter contains the identification number of the plant unit. It
R/W
helps to identify the location (plant unit) of an event. The handling of this
parameter is up to the control system or control person, respectively.
Display of current block state. Field subcode gives information about the
R
state current errors. The following errors can occur:
Configuration Error
Block was put Out of Service
The remaining fields give information about the state and the occurrence of
this alarm.
Display of active block errors. The following errors are possible:
R
Out of Service
Input Failure
Simulate Active
Block Configuration Error
Number of the transducer's logical hardware channel that is connected to
R/W
this Analog Input block. The only valid value is '1' (since the Transducer has
only one hardware channel). Every other value would cause an 'Block
Configuration Error' which is displayed in BLOCK_ERR.
The default value is '0'.
Raw value of the field device in percent of the PV range, with a status
R
reflecting the Transducer condition, before characterization (L_TYPE) or
filtering (PV_FTIME). See 5.3.3 for details.
Options for controlling access of host computer and local control panels to
R/W
operating, tuning and alarm parameters of the block.
NOTE:
This parameter is not supported by IFC090-FF.
With subject to the setting of HI_PRI, HI_ALM shows details about the high
R
alarm as acknowledge state and time stamp. See HI_PRI for details.
see also: HI_PRI, HI_LIM
With subject to the setting of HI_HI_PRI, HI_HI_ALM shows details about the
R
high high alarm as acknowledge state and time stamp. See HI_HI_PRI for
details.
see also: HI_HI_PRI, HI_HI_LIM
The limit value in engineering units as of the HI_HI_ALM is active (with
R/W
subject to HI_HI_PRI).
