3.4 Resource block
The resource block contains the parameters used to describe physical resources of
the device. It has no linkable inputs or outputs. It is opened by a click on the
resource line.
—
—E+H_CERABAR_S_XXXXXXXX
—RESOURCE_XXXXXXXX (RB)
—TRANSDUCER_XXXXXXXX (TBPR)
—ANALOG_INPUT_XXXXXXXX (AI)
If the NI-FBUS Configurator is being used, a series of file tabs appears on the screen.
The files can be opened to view and/or edit the parameters in the following table. A
short description of the parameter function appears on the side of the screen. A
change in the parameter is stored by pressing the WRITE CHANGES button when the
block is out of service. Press the READ ALL button to check the values stored in the
device. The following are of particular interest.
The function of the resource block parameters not described here can can be taken
from the Foundation Fieldbus specification, see
"http://www.fieldbus.org"
.
