3.8.13 DataCORDER Alarms
Alarm display is an independent DataCORDER
function. If an operating parameter is outside of the
expected range or a component does not return the
correct signals back to the DataCORDER an alarm is
generated. The DataCORDER contains a buffer of up to
eight alarms. A listing of the DataCORDER alarms is
provided in Table 3-10, page 3

3.8.14 ISO Trip Header
DataLINE provides the user with an interface to view/
modify current settings of the ISO trip header through
the ISO Trip Header screen.
The ISO Trip Header screen is displayed when the user
clicks on the “ISO Trip Header” button in the “Trip Func-
tions” Group Box on the System Tools screen.
F9 function - Provides the user with a shortcut for manu-
ally triggering the refresh operation. Before sending
modified parameter values, the user must ensure that a
successful connection is established with the controller.
If the connection is established with the DataCORDER,
the current contents of the ISO Trip Header from the Da-
taCORDER will be displayed in each field. If the connec-
tion is not established with the DataCORDER, all fields
on the screen will be displayed as “Xs.” If at any time dur-
ing the display of the ISO Trip Header screen the con-
nection is not established or is lost, the user is alerted to
the status of the connection.
After modifying the values and ensuring a successful
connection has been made with the DataCORDER,
click on the “Send” button to send the modified parame-
ter values.
The maximum allowed length of the ISO Trip Header is
128 characters. If the user tries to refresh the screen or
close the utility without sending the changes made on
the screen to the DataCORDER, the user is alerted with
a message.
