Active OPC Server Lite™ is Moxa’s free software package that
operates as an OPC driver for HMI/SCADA systems to achieve
faster response time with low network bandwidth consumption.
Conventional OPC servers typically use a polling method to connect
to Ethernet I/O devices, which continuously send commands to
In recent years, renewable energy such as wind power has become
more ubiquitous than ever. However, electricity from wind turbines is
erratic, and such fluctuations and interruptions can cause instability
of the power grid. The reason is that a drop in power at one point
can cause power surges elsewhere, which causes switches to short
circuit to counterbalance for the surges, which can result in blackouts.
To neutralize these fluctuations, wind-generated electricity must
first go through a transformer to even out the power voltage prior to
transmission. Transformers are indispensable to power systems since
The ioLogik E1200 is designed with a vertical form factor, and can
be either DIN-Rail or wall mounted. A stress-relief connector at
Moxa’s MXIO library supports the Windows, WinCE and Linux
operating systems, as well as the C++, VB/VC, and .NET development
platforms. The library’s large repository of C# and Visual Basic
sample code makes it easy to use high-level computer languages to
manage I/O devices and data transfer operations over an Ethernet
collect relevant data. Moxa’s Active OPC Server Lite offers active, or
“push” communications, which enables Moxa’s remote I/O products
to provide HMI/SCADA systems with instant I/O status reports by
using “Active Tags,” and use less bandwidth compared to the polling
method.
they ensure reliable operations. To avoid power failures, it is imperative
to monitor the status of the transformers; Moxa’s ioLogik E1200
series is perfect for monitoring transformers, oil temperature, and
gas pressure release and leaks thanks to its mixed I/O combination.
The ioLogik E1200 series comes in a compact form factor, enjoys a
wide operating temperature to ensure reliable performance in harsh
environments, and has a unique active tag function that reduces the
PC’s workload.
