News > Release 4.2
Release 4.2 of Tibbo AggreGate significantly increases system connectivity and
device management capabilities by introducing a number new features and
modules:
Modbus Device Driver. Full support for Modbus TCP, UDP, RTU, ASCII,
and BIN. Unlimited number of registers per device, with individual polling
and synchronization options.
OLE for Process Control (OPC) Device Driver. This driver lets LinkServer
act as an OPC Client and communicate with OPC Servers from different
manufacturers. OPC Data Access (DA) 2.0 specification is fully supported,
including arrays and other complex types. Connections are established using
Distributed COM (DCOM) technology, bringing several advantages over other
OPC Clients, such as interacting with OPC Servers running on remote machines
or accessing them from operating systems other than Microsoft Windows.
OPC Device Driver is fully functional on versions of LinkServer for Linux and
other operating systems.
Major improvements in device communications and synchronization. This
includes several methods of fine-grained synchronization control: custom
synchronization period for individual settings, Direct mode allowing
to avoid caching and perform all read/write operations directly to the device,
and suspending devices (temporarily disabling all device I/O).
Trackers. Trackers help monitor mission-critical server data in real-time.
All trackers are shown together in a single table that uses color highlighting
to indicate their state.
Alert Hysteresis. "Hysteresis" is a term describing the delay between
an event and the response to it. This feature allows operators to specify how
long must the alert condition last before the alert will is actually raised.
This is extremely helpful for defining alerts like "temperature is over 50
degrees for more than 10 minutes".
Alert acknowledgement by e-mail. LinkServer can check incoming mail by
polling a POP3 mailbox, so system operators may set alert acknowledgements by
replying to alert notification e-mail message and writing an acknowledgement
in the reply text.
Data-related context actions. Right-click on any data being viewed or
edited to access actions that can be applicable to process it, such as
Create Chart or View Change History.
Widgets auto-generation. Create a custom form for editing a complex
data structure with just a few mouse clicks. This form may be later fine-tuned in
the GUI Builder to better suit your needs.
Gauge, meter and
compass widget components. These highly configurable componends are ideal
for building custom Human-Machine Interfaces (HMI) for SCADA and sensor
monitoring applications.
Absolute positioning in widget containers. Combination of grid and
absolute layouts help building complex graphical interfaces.
Event-driven widget scripts. Scripts may be launched upon different
system events or just periodically. They can perform widget interface
modification on-the-fly, along with custom data processing.
Fully-functional embedded text editor with syntax highlighting. For
editing Java code, XML documents, SNMP MIB files, etc.
