Product Specification
Resource Block
The Resource Block (RB) contains a set of parameters
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.
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.”
Resource Block Parameter Table

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 block’s 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.
11 DEV_TYPE Manufacturer’s model number associated with the resource – used by interface
devices to locate the DD file for the resource.
12 DEV_REV Manufacturer revision number associated with the resource – used by an interface
device to locate the DD file for the resource.
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.
