2.3.1 Transducer Block Parameters
The first six parameters in the TRANSDUCER Block are the
universal parameters discussed in section 2.1.1. After the
universal parameters, six additional parameters are required
for Transducer Blocks. The most notable of these parame-
ters are
UPDATE_EVT
and
BLOCK_ALM
. It should be
noted that these six additional parameters must exist but do
not have to be implemented.
An important device-specific parameter found later in the
TRANSDUCER Block list is
PRESENT_STATUS
, which
displays the status of the device. If more than one message
exists, then the messages are displayed in priority order.
If
PRESENT_STATUS
indicates a problem, refer to
Section 5.2, Troubleshooting.
For a complete list of Transducer Block Parameters, refer
to table in the Appendix.
NOTE: The user should compare the DD file and revision number of the
device with the HOST system to ensure they are at the same
revision level.
Refer to the DD Revision Table Section 1.2.1.
Refer to Appendix B for a complete list of the three Transducer
Block parameter sets.
2.3.2 Password Parameters
To change a parameter at the local user interface, host, or
fieldbus interface, a value matching the user password must
be entered (Default = 0). If a static parameter is changed
from the local user interface, the Associated Transducer
Block goes Out of Service (OOS).
Refer to the Section 4.3 for additional information regard-
ing passwords.
After five minutes with no keypad activity, the entered pass-
word expires. However, the device must be placed back in
service from the Host System.
2.3.3 PULSAR Model R86 FF Configuration Parameters
One of the main advantages of the PULSAR Model R86 FF
Pulse Burst Radar transmitter is that the device can be deliv-
ered pre-configured to the user.
In addition, F
OUNDATION
fieldbus
™
provides the ability to
monitor changes and make adjustments to a transmitter.
The Fieldbus
™
concept allows a user to make adjustments if
deemed necessary.
