Index
Parameter
Description
1
ST_REV
The revision level of the static data associated with the function block. To support
tracking changes in static parameter attributes, the associated blockís static revision
parameter will be incremented each time a static parameter attribute value is written.
2
TAG_DESC
The user description of the intended application of the block.
3
STRATEGY
The strategy field can be used to identify grouping of blocks. This data is not
checked or processed by the block.
4
ALERT_KEY
The identification number of the plant unit. This information may be used in the host
for sorting alarms, etc.
5
MODE_BLK
The actual, target, permitted, and normal modes of the block.
6
BLOCK_ERR
This parameter reflects the error status associated with the hardware or software
components associated with a block. It is a bit string, so that multiple errors may be
shown.
7
RS_STATE
State of the function block application state machine.
8
TEST_RW
Read/write test parameter – used only for conformance testing.
9
DD_RESOURCE
String identifying the tag of the resource, which contains the Device Description for
this resource.
10
MANUFAC_ID
Manufacturer identification number – used by an interface device to locate the DD file
for the resource.
Resource Block Parameter Table
Resource Block
The Resource Block (RB) contains a set of parame-
ters that define characteristics of the physical
BUSwitch
™
sub-components (function blocks and
transducer block). Some of these parameters are
considered “operational” because they affect or reflect
the operation of function blocks. Others contain more
general data about the device.
MANUFAC_ID, DEV_TYPE, DEV_REV, and DD_REV
provide information to the control system about which
device description to use. All of the RB parameter
data is “contained” meaning no links are made to
this block. No device configuration data is stored in
this block.
General function block operation is reflected in the
RB. MODE_BLK may be used to override the Target
Modes of all function blocks and transducer block.
Supported Modes (MODE_BLK)
O/S, IMAN, AUTO (Factory default = Auto)
Alarm Types
Standard block alarm plus a discrete alarm for
write lock.
Device Initialization
The parameter RESTART permits varying degrees
of initialization.
CAUTION
Initializing with the setting “Defaults” will
reset the device to the board manufacturer’s
defaults, not the Flowserve defaults shown in
this document. When using this command,
users will have to reestablish all the critical
Flowserve factory defaults highlighted in each
block section. Items shaded “black” must be
configured.
1. Write the value “Defaults” to RESTART.
2. Read the RESTART value. It should equal 1.
3. Turn off and then turn on the device.
Users may utilize the other levels of restart at their
discretion.
Resource Block Parameter Table
The following table provides a complete list of all
RB parameters. There are no critical default RB
parameter settings affected by a “Default” RESTART,
however Flowserve recommends setting the
MODE_BLK value to “Auto.”
