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 DEVICE_STATUS, which
displays the status of the device. If more than one message
exists, then the messages are displayed in priority order.
If DEVICE_STATUS indicates a problem, refer to
Section 5.0, Troubleshooting.
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.
Please refer to the DD Revision Table Section 1.2.1.
Please refer to Appendix B for a complete list of the three
Transducer Block parameter sets.
To change a parameter at the local user interface, a value
matching the user password must be entered (Default = 1).
If a static parameter is changed from the local user interface,
the Associated Transducer Block goes Out of Service
(OOS).
Please refer to the Section 4.3 for additional information
regarding passwords.
After 5 minutes with no keypad activity, the entered pass-
word expires. However, the device must be placed back in
service from the Host System.
From the Host system network, the instrument always
behaves as if it is in the user password mode by default. In
other words, it is not necessary to enter the user password in
order to write most parameters from the Host system.
One of the main advantages of the Eclipse Model 706 FF
GWR transmitter is that the device can be delivered pre-
configured to the user.
