FieldPoint Explorer to update your
.IAK
file. If necessary, consult your FieldPoint online
help for detailed instructions on using FieldPoint Explorer. To re-import the
.IAK file,
unselect the Import alias information checkbox and click on OK. Reopen the FieldPoint
object dialog box and select the Import alias information checkbox again. When you
click on OK, Lookout
Direct
re-imports the new
.IAK
file infomation.
Serial port specifies which COM port the object uses for communicating
to the external device. This does not specify the communication type.
Communication type is determined by the Options»Serial Ports... menu
command.
Data rate indicates the baud rate that Lookout
Direct
uses to communicate
with the hardware device. This setting should match the selection made on
each of your network modules.
Phone number specifies the number to be dialed if the selected serial port
is configured for dial-up. This number only applies to the individual
protocol object.
PollRate is a numeric expression that determines how often to poll the
device. The object then polls the device at the specified time interval.
Ordinarily, this is a simple time constant such as 0:01 (one second). See
Numeric Data Members in Chapter 2, How LookoutDirect Works, of the
Getting Started with LookoutDirect manual for information on entering
time constants.
Poll is a logical expression. When transitioned from FALSE to TRUE,
LookoutDirect
polls the device. This can be a simple expression, like the
signal from a pushbutton, or it can be a complex algorithm.
Communication alarm priority determines the priority level of alarms
generated by the FieldPoint object. Such alarms are typically related to
communications with the physical device.
Retry attempts specifies the consecutive number of times Lookout
Direct
attempts to establish communications with a device if it is not getting a
valid response. After it tries the number of Retry attempts specified, the
FieldPoint object generates an alarm and releases the COM port. Refer to
Chapter 3,
Serial Communications, in the LookoutDirect Developer’s
Manual
for more information.
Receive timeout is the time delay Lookout
Direct
uses in waiting for a
response from a device before retrying the request.
