>>> RTU PROGRAMMER VERSION 3.03 HELP FILE <<<(continued)
Enabling RF spy mode on one RTU allows that RTU to report all incoming RF
messages over the serial link. These messages can be displayed using the RF Spy
screen available from the Utilities menu. While the RF Spy feature is enabled,
the unit will only operate in RF Spy mode and will not respond to the RF
1.2
Send List:
The send list indicates up to four other RTU's to which this RTU can send its
status. All inputs will be sent to each of the units on the list. Enter an ID of 0
(zero) for any unused entries. If any of these listed units fail to acknowledge the
message, the fail-safe state indicated by the letter next to that unit's ID will be
set. The lettered fail-safe states are listed in the lower right corner of the system
1.3
Repeat List:
When this unit receives a message from another unit, it can use the message
AND send it along to other RTU's. This information is configured in the repeat
list. Each incoming message can be repeated to up to four RTU's. The first
column indicates the unit that originates the message and the next four columns
show the ID's of the units which will receive the message.
1.4
Fail-Safe States:
If a unit fails to receive an acknowledge a fail-safe condition can be set. Each of
the four outputs can be set to a distinct fail-safe condition. The analogs can be
set to any valu e from 0% to 100%. A "no change" option is also available. For
the analog outputs, the "no change" is indicated by a 999%. Any number over
101 % will be interpreted as a "no change". The programmer will automatically
replace this number with "999%" when it downloads the information to the
RTU. For the digital outputs, the choices are: open on fail, close on fail, or no
change on fail. The R column indicates whether the output should revert to its
initial condition when the signal is re-acquired. The choices for the field are yes
orno.
Example 1:
Revert to initial condition is selected for a digital output.
The initial condition for this output is relay open.
The fail-safe condition for this output is relay closed.
This output is not actively controlled by any other RTU.
The relay will be open when the system is started.
The relay will close when the RF link is lost.
The relay will open when the RF link is regained.
Example 2:
Revert to initial condition is NOT selected for digital output.
The initial condition for this output is relay open.
The fail-safe condition for this output is relay closed.
This output is not actively controlled by any other RTU.
The relay will be open when the system is started.
The relay will close when the RF link is lost.
The relay will remain closed after the RF link is regained.
