2.3.3 New pre-installed fonts
The setup package contains a number of new true-type fonts for use in L-Vis and L-WEB
projects. Have a look at the new choices in
fonts\loytec
and
fonts\truetype
.
2.3.4 More operations supporting undo
The new configuration software now allows changes done to base paths of templates or
template instances as well as changes done to an entire batch of data points via the data
point reference manager to be undone. For example, a batch reassign of data points can now
be undone conveniently in case the reassign lead to undesired results.
2.3.5 L-WEB projects use true-type fonts for the preview
Since recent LWEB-802/803 client software is able to use embedded true type fonts in most
cases, the configuration software now also shows the project preview using true type fonts,
instead of the pre-rendered pixel fonts which LWEB-802 would use as a fallback in case
the embedded true type font cannot be used. Note that some combinations of web browser
and font may still cause LWEB-802 to fall back to the pre-rendered pixel font.
2.3.6 Improved performance and memory usage
Especially with larger projects, the new configuration software provides a significant
performance improvement for many operations, as well as reduced memory consumption.
2.3.7 Dual-Ethernet with Separate Networks
L-VIS models with two Ethernet interfaces can now be configured to work with separate
and isolated IP networks. For example, one Ethernet interface can be accessed over HTTPS
from a WAN connected to Ethernet 2 while the building network services are running
locally on the LAN connected to Ethernet 1. For configuration, the device provides separate
Ethernet tabs in the port configuration which allow selecting the offered services on each
interface.
2.3.8 WLAN Interface
In combination with the external LWLAN-800 interface, all models equipped with a USB
host interface provide new configuration tabs for wireless IP networks. Similar to the
second Ethernet interface, one can choose which protocols are available on the wireless
network. The wireless interface can be configured as a WLAN client, access point, or mesh
node. Using the latter, a wireless mesh network of LOYTEC devices can be built.
2.3.9 OPC UA Server
The new LVIS-3ME model series provide an OPC UA server. This server supports the
OPC UA binary protocol and exposes the same OPC tags as the OPC XML-DA server. In
addition, OPC UA offers superior security features as well as a more efficient data transfer.
For more information on the OPC UA server please refer to Section
2.3.10 Alarm Server Ack-All Data Point
Alarm servers now provide a special ackAll property data point. When writing TRUE on
that data point all currently active alarms on the alarm server are acknowledged.
2.3.11 Format Strings in E-Mails
Data point variables used in e-mail templates can now use format strings to specify their
numeric appearance in the e-mail text.
2.3.12 Output NVs with Integrated Feedback
Output network variables (NVs) are used to send updates to remote nodes. In order to poll
back the actual value of the remote variable, a feedback data point had to be created for the
