Parameter
ST_REV
TAG_DESC
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 permitted standard 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 associate
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
Input value and status.
See IN_D1
S, W
Options that the user can select to alter multiple out-
put block processing.
S, W
The delay time in seconds. Time from the detection
of a condition initiating a fault state action in an output
block until the actual initiation of the output action of
the block output. That is provided that the condition
exists continuously during this time interval as sam-
pled by the output block.
S, W
The preset discrete value to be used if failure occurs
in IN_D1. This value is ignored if the "Fault state to
value 1" in the MO_OPTS parameter is false.
S, W
See FSTATE_VAL_D1
This parameter is used to signal to the PCS that a
parameter marked with "S" was overwritten provided
that the PCS supports alarm messages.
This parameter is used to signal to the PCS diagnos-
tic messages displayed in BLOCK_ERR provided
that the PCS supports alarm messages.
Char.
Description
During each writing process to a parameter marked with "S",
the parameter ST_REV is increased by 1.
W, S
Use this parameter to assign a tag to the valve interface (mea-
suring point designation) in the plant or process.
