Description
This parameter is used to signal to the PCS that a
parameter marked with "S" was overwritten, provided
the PCS supports alarm messages.
This parameter is used to signal diagnostic mes-
sages that are displayed in BLOCK_ERR to the PCS,
provided the PCS supports alarm messages.
The current status of the alarm messages of the
block.
S, W
Determines if alarms of the function block have to be
confirmed or not.
S, W
Priority of discrete alarm
S, W
Digital input state, in which an alarm is supposed to
be generated.
S, W
The current state of the discrete alarm, along with a
timestamp and datestamp.
Char.
Description
S
During each writing process to a parameter marked
with "S", the parameter ST_REV is increased by 1.
S, W
Use this parameter to assign a tag to the valve inter-
face (measuring point designation) in the plant or
process.
S, W
The strategy field can be used to identify comprising
blocks. This data is not controlled or used by the
block.
S, W
Identification number of the plant component. This
information can be used by the control computer,
e.g., to sort alarms. Valid values are 1 ... 65536.
S, W
Displays the current, allowed normal mode and the
target mode of the block. The target mode can be set
to the values "Auto" or "Out of Service".
Default: Auto
Displays diagnostic messages of the block.
S, W
The channel parameter is used to logically associ-
ated signal converter and function block information.
During block configuration, the value of the channel
number can be configured in input and output func-
tion blocks. See chapter 8.3
Output value and status.
Manual mode permits the operating personnel or
engineer to manually substitute the value of OUT_D,
for test or other purposes.
See OUT_D1
This parameter is used to signal to the PCS that a
parameter marked with "S" was overwritten if the
PCS supports alarm messages.
This parameter is used to signal to the PCS diagnos-
tic messages displayed in BLOCK_ERR, if the PCS
supports alarm messages.
