Revision 4 Foundation Fieldbus RMA803 Remote Indicator User's Guide Page 35
5.3 Resource block
The Resource block is used to describe characteristics of the Fieldbus device such as the device
name, manufacturer, and serial number. The block does not contain any input or output parameters.
The block contains data that is specific to the hardware associated with the resource. The resource
block monitors and controls the general operation of the device hardware. For example, if the
resource block is in out of service mode, it affects all the other blocks. The ITK_VER parameter is
used to identify the version of the Interoperability Tester. The RMA803 Remote Indicator’s
Revision and Versions, and Model Number can be obtained by executing the methods available in
the resource block.
The block modes are used to control major states of the resource:
• The OOS mode stops all function block execution.
• The Actual mode of the function blocks changes to OOS but the target mode does not change.
• The AUTO mode allows normal operation of the resource.
Configuring the Resource block
The Resource block supports scalar input only as HARD_TYPES. This parameter is a read-only bit
string that indicates the types of hardware that are available for this resource. The RS_STATE
parameter contains the operational state of the Function Block Application for the data containing
that resource block.
RESTART
The RESTART parameter allows degrees of initialization of the resource.
Restart Operation
Run (1) The passive state of the parameter.
Restart resource (2) Discards unnecessary alarms, and also discards the
resource dynamic values.
Restart with defaults (3) Resets all configurable function block application objects to
their initial value, which is their value before any
configuration is done.
Restart processor (4) Provides a way to press the reset button on the processor
associated with the resource.
