includes adds date stamping to the log pane.
New Features in Release 2.1
Release 2.1 of the LNS DDE Server includes the following new features:
• Expanded Polling Capability - When used with either an LNS fast network
interface attached to a LonWorks channel, or an IP network interface attached to
a LonWorks/IP channel, the LNS DDE Server can now poll up to 1,000 points
simultaneously, instead of the maximum of 2 in the previous release. The result
is a significant improvement in the number of points per second that may be
polled.
• Expanded Binding Capability - When used with either an LNS fast network
interface attached to a LonWorks channel, or an IP network interface attached to
a LonWorks/IP channel, the LNS DDE Server now has an address table with
32,768 entries instead of the 16 entries in the previous release. This enables the
LNS DDE Server PC to be a member of every group within a domain, eliminating
many of the binding constraints of the previous release, and supporting many
more bound connections.
• LNS 3 Runtime - Release 2.1 of the LNS DDE Server installs the LNS 3
Runtime. This provides significantly improved performance when using either
an LNS fast network interface attached to a LonWorks channel, or an IP network
interface attached to a LonWorks/IP channel. The performance improvements
are a result of faster throughput through the LNS runtime and the network
interface, and the increased capacities for polling and binding.
• LonWorks/IP Channel Support - Release 2.1 of the LNS DDE Server can be used
to monitor and control remote full client networks over a LonWorks/IP Channel.
This allows the LNS Server PC to be attached directly to an IP channel without
requiring an LNS network interface card. This also increases performance for
most monitoring and control applications. For example, an application that
could previously poll no more than 35 points per second may be able to poll over
600 points per second from a LonWorks/IP client. A LonWorks/IP client can
receive over 1200 updates per second for bound updates. Actual performance
depends on your computer hardware and application.
• Wonderware SuiteLink Support -- The Wonderware SuiteLink protocol is now
supported for accessing the LNS DDE Server, in addition to the Microsoft DDE
protocol. This provides improved performance for Wonderware InTouch clients.
• Multiple Network Support - A single instance of the LNS DDE Server can now
simultaneously open up to 100 LNS networks through a single LNS network
interface. This includes both local and remote networks. This allows a single
DDE application to provide an interface to multiple networks, either through a
