ET-7000/PET-7000/ET-7200/PET-7200 (Web based)  
   
 
The ET-7x00/PET-7x00, 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 surfi ng the Internet.

Besides Web HMI function, no more programming or HTML skills are required; creating dynamic and attractive web pages for I/O monitoring and I/O control would be fun to engineers ever after. The ET-7x00/PET-7x00 offers easy and safe access for users from anytime and anywhere! In addition, the ET-7x00/PET-7x00 also supports Modbus TCP protocol that makes perfect integration to SCADA software.

Furthermore, PET-7x00 features “PoE” that not only Ethernet but also power is carried through an Ethernet cable. This feature makes installation of PET-7x00 a piece of cake. Imagine that no more unnecessary wires, only an Ethernet cable takes care of everything in the fi eld.
 
   
 
   
1. Power over Ethernet (PoE)
The PET-7000/PET-7200 series module can be powered by an IEEE802.3af compliant PoE switch. Both Ethernet and power can be carried by an Ethernet cable eliminating the need for additional wiring and power supply.
 
   
 
   
2. Daisy-Chain Ethernet Cabling
The ET-7200/PET-7200 Series has a built-in two-port Ethernet switch to implement daisy-chain topology. The cabling is much easier and total costs of cable and switch are significantly reduced.
 
   
 
   
3. LAN Bypass
LAN Bypass feature guarantees the Ethernet communication. It will automatically active to continue the network traffic when the ET-7200/
PET-7200 looses its power.
 
   
4. Communication Security
Account and password are needed when logging into the 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.

6. Built-in I/O
Various I/O components are mixed with multiple channels in a single I/O module, which provides the most cost effective I/O usage and enhances performance of the I/O operations.

7. Dual Watchdog
The Dual Watchdog is consists of a Module Watchdog and a Communication Watchdog. The action of AO,DO are also associated to 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 I/O module. The timeout of the communication Watchdog is proprgrammable, when the I/O 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. Highly Reliable Under Harsh Environment
  • Wide Operating Temperature Range: -25 ~ +75°C
  • torage Temperature: -30 ~ +80°C
  • Humidity 10 ~ 90% RH (Non-condensing)
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 I/O module can poll the status of remote AI/DI devices and then use the Modbus TCP protocol to continuously write to a local AO/DO channels in the background.
 
   
10. Power-on Value and Safe Value
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.
