1.Introduction
The OME-ET-7000/OME-PET-7000 is a web-enabled Ethernet I/O module featuring
a built-in web server that allows remote configuration, I/O monitoring and I/O control
simply by using a standard browser. Remote control is as easy as surfing the
Internet. In addition, the web HMI function means that programming or HTML skills
are no longer required, so creating dynamic and attractive web pages for I/O
monitoring and I/O control purposes will be more enjoyable for engineers in the
future. The OME-ET-7000/OME-PET-7000 offers easy and safe access for users at
any time and from anywhere, and also supports the Modbus/TCP protocol that
ensures perfect integration with SCADAsoftware. Furthermore, the OME-PET-7000
features “PoE” technology, meaning that not only is data transmitted through the
Ethernet cable, but also power, making installation of the OME-PET-7000 extremely
easy. Imagine no more unnecessary wires, with only an Ethernet cable being
required to take care of everything in the field.
This series of analog modules is specifically designed to interface with analog
current and voltage input signals, and all analog input channels can be individually
configured for different kinds of analog input. Thanks to its intuitive design,
measurement of either current or voltage input signal is easy and can be selected
via a jumper. Thus an external resistor is no longer needed.

The "OME-ET-7018Z/OME-PET-7018Z/OME-ET-7019Z/OME-PET-7019Z" is a
thermocouple module that is specifically designed for extremely accurate
thermocouple measurement. The "Z" features automatic cold-junction
compensation for each channel to ensure temperature output consistency and
stable temperature output in the field. Open thermocouple detection and
ESD/EFT/Surge protection mechanisms are also included.
Comparison between OME-ET-7000 and OME-PET-7000
The OME-PET-7000 has some unique features that different from the
OME-ET-7000

OME-PET-7000 = Power over Ethernet + OME-ET-7000
The OME-PET-7000 includes integrated Power over Ethernet (PoE) technology that
allows both power and data to be carried over a single Ethernet cable, meaning that
a device can operate solely from the power it receives through the data cable. This
innovation allows greater flexibility in office design, higher efficiency in systems
design, and faster turnaround time in installation and implementation. The
OME-PET-7000 features true IEEE 802.3af-compliant (classification, Class 1) PoE
using both Ethernet pairs (Category 5 Ethernet cable). The OME-PET-7000 can also
receive power from auxiliary power sources such as DC adapters and external
battery packs, in addition to the PoE-enabled network. This is a desirable feature
when the total system power requirements exceed the PoE's load capacity.
Furthermore, with the benefit of the auxiliary power option, the OME-PET-7000 can
be easily integrated into a standard Ethernet (non-PoE) system.

Industrial PoE Solution
The PoE switch is the ideal power source when using the OME-PET-7000 module.
The NS-205PSE automatically detects whether the connected devices are
PoE-enabled or not, which ensures that the PoE swtch will function in conjunction
with both PoE and non-PoE devices simultaneously.

More information about the OME-PET-7000 series
There are two ways for OME-PET-7000 series devices to obtain power. The first is
through the Ethernet via a PoE switch; the second one is the usual method through
wiring from an external power source. External power source should range from +12
VDC to 48 VDC. The reason that the second method has been retained is because it
might still prove useful for different applications in a variety of scenarios. The
OME-PET-7000 is also equipped with an LED to indicate whether or not the power
is being supplied via a PoE Switch.

1.1. Features
The OME-ET-7000/OME-PET-7000 module offers the most comprehensive
configuration focused on meeting specific application requirements. The following
details the features designed to simplify installation, configuration and application.
Built-in Web Server
Each OME-ET-7000/OME-PET-7000 module has a built-in web server that
allows users to easily configure, monitor and control the module from a remote
location using a standard web browser.
Web HMI
The Web HMI function enables users to create dynamic and attractive web
pages that can be used to monitor and control the I/O points. Users can upload
specific I/O layout diagrams in either bmp, jpg, or gif format, and define a
description for each I/O point. No HTML or Java skills are in order to create the
web pages.

Page: 5
Communication Security
An account and password are required when logging into the
OME-ET-7000/OME-PET-7000 web server. An IP Address filter is also
included, which can be used to either allow or deny connections from specific
IP addresses.
Modbus/TCP, Modbus/UDP Protocol
The Modbus/TCP, and Modbus/UDP slave functions on the Ethernet Port can
be used to provide data to remote HMI/SCADAsoftware based on the
Modbus/TCP driver.
Built-in Multi-function I/O
A variety of I/O components are combined with multiple channels in a single
module, which provides the most cost effective I/O usage and enhances the
performance of the I/O operations.
Automatic MDI/MDI-X Crossover for Plug-and-Play
The RJ-45 Port supports automatic MDI/MDI-x, meaning that it can
automatically detect the type of connection to the Ethernet device without
requiring dedicated straight or crossover cables.
Built-in Dual Watchdog
The Dual Watchdog consists of a Module Watchdog and a Host Watchdog.
The activities of the outputs are also associated with the Dual Watchdog.
The Module Watchdog is a built-in hardware circuit that monitors the
operating status of the module and will reset the module if a failure occurs in
either the hardware or the software.
The Host Watchdog is a software function that monitors the operating status
of the host, and is used to prevent network communication problems or host
failures. When a host watchdog timeout occurs, the module will reset all
outputs to a safe state in order to prevent any erroneous operations of the
controlled target.

Highly Reliable Under Harsh Environments
The OME-ET-7000/OME-PET-7000 is housed in a plastic-based case with a
vertical style ventilator that helps to cool the working environment inside the
case.
Operating Temperature: -25 ~ +75 °C
Storage Temperature: -30 ~ +80 °C
Humidity: 10 ~ 90% RH (non-condensing)
I/O Pair Connection
The I/O Pair Connection function is used to create a DI to DO (AI toAO) pair
via the Ethernet. Once the configuration is complete, the
OME-ET-7000/OME-PET-7000 module can poll the status of the remote input
devices using the Modbus TCP protocol, and then continuously write to the
local outputs in the background.

1.2.2. Back Panel
The back panel of the OME-ET-7000/OME-PET-7000 module contains the frame
ground and the operating mode selector switch.
Operating Mode Selector Switch
Init Mode:
This mode is used for MiniOS7 configuration.
Normal Mode:
This mode is used to execute and run firmware.
On the OME-ET-7000/OME-PET-7000 module, the operating mode selector
switch should usually be in the Normal position. The switch should only be
moved from the Normal position to the Init position when updating the
OME-ET-7000/OME-PET-7000 firmware or the OS. Once the update has been
completed, ensure that the switch is returned to the Normal position.

Frame Ground
Electronic circuits are constantly vulnerable to Electrostatic Discharge (ESD),
which becomes worse in a continental climate area. The
OME-ET-7000/OME-PET-7000 series features a new design for the frame
ground that provides a path for bypassing ESD, allowing enhanced static
(ESD) protection capabilities and ensuring that the module is more reliable.
Choosing either of the following options will provide a better level of protection
for the module:
The OME-ET-7000/OME-PET-7000 has a metallic board attached to the back
of the plastic case, shown as “1” in the figure below.
When mounted to a DIN-Rail, connect the DIN-Rail to the earth ground
because the DIN-Rail is in contact with the upper frame ground, as shown as
“2” in the figure below.
