ALERT_KEY R/W
ALERT_KEY parameter contains the identification number of the plant unit. It
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.
BLOCK_ALM R
Display of current block state. Field
subcode
gives information about the
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.
BLOCK_ERR R
Display of active block errors. The following errors are possible:
Out of Service
block is in
Out of Service
mode
Input
Failure
SIMULATE.status
is
Bad:NonSpecific
Simulate
Active
SIMULATE.enable
= yes
Block Configuration Error
channel unit !=
XD_SCALE.unit
, or
CHANNEL
!= 1, or
L_TYPE
is uninitalized
CHANNEL R/W
Number of the transducer’s logical hardware channel that is connected to
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’.
FIELD_VAL R
Raw value of the field device in percent of the
PV
range, with a status
reflecting the Transducer condition, before characterization (

) or
filtering (
PV_FTIME
). See 5.3.3 for details.
GRANT_DENY R/W
Options for controlling access of host computer and local control panels to
