The OME-ET-7000/OME-PET-7000 Series, a web-based Ethernet I/O module, features a built-in web server which allows configuration, I/O monitoring and I/O control by simply using a regular web browser. Remote control is as easy as browsing the Internet. With the web HMI function, programming or HTML skills are not required creating dynamic and attractive web pages for I/O monitoring and I/O control is easy. The OME-ET-7000/OME-PET-7000 Series offers easy and safe access for users at any time, from any location. In addition, the OME-ET-7000/OME-PET-7000 Series also supports Modbus TCP protocol that makes perfect integration to SCADA software. OME-PET-7000 features “PoE” where not only data but also power is carried through an Ethernet cable. This feature makes installation of OME-PET-7000 easy. No more unnecessary wires only an ethernet cable that takes care of everything in the field.
Features
1. Power over Ethernet (PoE) The OME-PET-7000 series module can be powered by an IEEE802.3af compliant PoE switch. Both data and power can be carried by an Ethernet cable eliminating the need for additional wiring and power supply.
2. Built-in Web Server Each OME-ET-7000/OME-PET-7000 module has a Built-in web server that allows the users to easily configure, monitor and control the module from a remote location using a regular web browser.
3. Web HMI The Web HMI function allows the users to create dynamic and attractive web pages to monitor and control the I/O points. Users can upload specific I/O layout pictures (bmp, jpg, gif format) and define a description for each I/O point. No HTML or Java skills are needed to create the web pages.
4. Communication Security Account and password are needed when logging into the OME-ET-7000 web server. An IP address filter is also included, which can be used to allow or deny connections with specific IP addresses.
5. Support for both Modbus® TCP and Modbus UDP Protocols The Modbus TCP, Modbus UDP slave function on the Ethernet port can be used to provide data to remote SCADA software. A free MODBU S software development toolkit is included on the utility software CD that is supplied with the OME-ET-7000/ OME-PET-7000 Series modules.
6. Built-in I/O Various I/O components are mixed with multiple channels in a single module, which provides the most cost effective I/O usage and enhances performance of the I/O operations.
7. Dual Watchdog The Dual Watchdog consists of a module Watchdog and a communication Watchdog. The action of AO/DO are also associated with the Dual Watchdog. Module Watchdog is a Built-in hardware circuit to monitor the operation of the module and will reset the CPU if a failure occurs in the hardware or the software. Then the power-on value of AO/DO will be loaded. Communication Watchdog is a software function to monitor the communication between the host and the OME-ET-7000/OME-PET-7000 module. The timeout of the communication Watchdog is programmable, when the OME-ET-7000/OME-PET-7000 doesn’t receive commands from the host for a while, the watchdog forces the AO/DO to pre-programmed Safe Value to prevent unpredicatable damage of the connected devices.
8. Power-on Value and Safe Value![](jpg/ome-et-7000_ethernet_art.jpg)
Besides setting by the set AO/DO commands, the AO/DO can be set under two other conditions.
Power-on Value: The Power-on Value is loaded into the AO/DO under 3 conditions: Power-on, reset by Module Watchdog, reset by reset command.
Safe Value: When the Communication Watchdog is enabled and a Communication Watchdog timeout occurs, the “safe value” is loaded into the AO/DO.
9. I/O Pair Connection This function is used to create a AI/DI to AO/DO pair through the Ethernet. Once the configuration is completed, the OME-ET-7000/OME-PET-7000 module can poll the status of remote AI/DI devices and then use the Modbus TCP protocol to continuously write to local AO/DO channels in the background.
10. Highly Reliable Under Harsh Environments • Wide Operating Temperature Range: -25 to 75°C (-13 to 167°F)
• Storage Temperature: -30 to 80°C (-22 to 176°F)
• Humidity 10 to 90% RH (non-condensing)
