 Q1. |
In MOXA's Ethernet I/O product line, which models support Active Ethernet I/O? |
| A. |
Active Ethernet I/O is supported by ioLogik E2000 Ethernet I/O servers |
| Top |
| Q2. |
Can I use Active Ethernet I/O with Click&Go™ logic for alarm control applications? |
| A. |
YES. MOXA's Active Ethernet I/O works perfectly
for alarm control and general I/O on/off control
systems. However, Moxa Active Ethernet I/O is
NOT designed for high-speed motion control or
machinery
control
applications. |

| Q3. |
Can
Active Ethernet I/O provide local control of
digital input and output devices, without
requiring a PC? |
| A. |
YES. You do not need to install a field PC for simple local control. After the Click&Go™ logic
is configured, Active Ethernet I/O can operate
independently without connecting
to a PC. |

| Q4. |
Can Active Ethernet I/O be adapted into existing SCADA software systems? |
| A. |
YES. Active Ethernet I/O supports Modbus/TCP
over Ethernet. It is compatible with standard
Modicon drivers for most SCADA software,
including Wonderware, Citect, and iFix. Moreover,
you can establish additional value-added applications
on top of Active Ethernet I/O, such as simple
local control or event mailing. |

| Q5. |
Is Click&Go logic control available for E2240 Ethernet analog I/O servers? |
A.
|
YES. For
typical applications, E2240 Ethernet analog
I/O servers can use Click&Go logic to act
as level-sensing triggers. For example, the
analog
I/O server could be configured to
- send an e-mail when the analog input reaches an upper or lower limit
- send a TCP/UDP message when the analog input reaches a specific value
With Click&Go, the analog input value can
be represented using raw data (in decimal), percentage
(%), or engineering value (mV, voltage, mA). |

| Q6. |
Can the ioLogik E2210 support digital input, counter input, digital output, and pulse output at the same time? |
| A. |
YES. The E2210 supports multiple functions
that can be configured independently for each
I/O channel. For digital input channels, a mechanical
switch can be connected as a pure ON/OFF device
or as a counting device. For digital output channels,
an alarm light can be connected for pure ON/OFF
display or for flashing pulsed output. The desired
mode of each channel is selectable by software. |

| Q7. |
Is a software library available for PCs to access I/O data from the Active Ethernet I/O server? |
A.
|
YES. A MXIO DLL library is provided that
can help you access Active Ethernet I/O data.
The programming library is designed to be intuitive
and easy to learn. I/O data can be obtained
without knowledge of Modbus addressing
and protocols. Functions include standard acquisition
and control of DI, DO, AI, AO, counter, and
pulse output, as well as APIs for TCP and UDP
I/O data retrieval.
The MXIO programming library currently supports Visual Basic, Visual C++, Borland C++ Builder under Windows. Support for Linux and Windows .NET is scheduled for second half 2008.
In addition, the existing Linux, uCLinux, and WinCE library for MOXA's UC-7420 embedded computer can be used to access I/O data. |

| Q8. |
How does Active Ethernet I/O reduce your total system costs by up to 80%? |
A.
|
Traditional remote I/O relies on a PC
controller for operation. This can generate
up to USD$1500 in extra
costs for hardware, operating system, and SCADA
software (costs may differ between different
regions).
Active Ethernet I/O does not require a separate
PC controller, additional software, or programming
for operation. It is designed
to provide all the functionality of traditional
remote I/O systems in one package, while
including peer-to-peer communication over Ethernet,
local
output control, and automated I/O event reporting.
Since a separate PC controller is not required,
there are no costs associated with operating
systems, proprietary SCADA software, or additional
wiring. Also, Active Ethernet I/O is designed
for easy setup by beginners, saving both
time and money spent on specialized programming.
These savings can accumulate to a dramatic
80% reduction in total system costs, compared
to a similarly equipped traditional remote
I/O system. |
