ServiceType
Summary Determines the service type used when sending explicit
messages with a message monitor point.
You cannot set this property through the CurrentOptions
property of a temporary monitor point, as the CurrentOptions
properties of all temporary monitor points are not accessible.
However, you can set this property through the NvOptions or
MsgOptions property of a temporary monitor set to determine
the default messaging service that will be applied to all
monitor points as they are added to the set.
See the Monitor and Control chapter of the OpenLNS
Programmer’s Guide for more information.
Availability Local, full, lightweight, and independent clients. Note that
temporary MonitorSet objects and temporary monitor points
are not available on Independent clients.
Syntax retryValue = monOptsObject.Retries
Element Description
retryValue The valid values for this property,
which are enumerated in the
ConstServiceTypes constant, are as
follows:
0 lcaSvcAckd
Acknowledged messaging service.
The device sends an
acknowledgment message after it
has received the message.
If your application will be sending
messages to large numbers of
devices at once, one of the
unacknowledged messaging services
may be desirable, as the
acknowledgment messages may
generate a significant amount of
network traffic.
1 lcaSvcUnackdRpt
Unacknowledged repeat messaging
