Chapter 1. Introduction The PET-7026/ET-7026, 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. Besides, with the web HMI function, no more programming or HTML skills are needed; creating dynamic and attractive web pages for I/O monitoring and I/O control would be fun to engineers ever after.
PAGE 7
The features of the PET-7026 differ from the ET-7026 The PET-7026 has integrated Power-over-Ethernet (PoE), it allows power and data to be carried over a single Ethernet cable, so 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 set-up and implementation. The PET-7026 feature true IEEE 802.

1.1. Features  Built in Web Server Each PET-7000/ET-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 regular web browser.  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.

 Communication Security Account and password are required when logging into the PET-7000/ET-7000 web server. An IP address filter is also included, which can be used to allow or deny connections with specific IP addresses.  Modbus Protocol The Modbus/TCP slave function on the Ethernet port can be used to provide data to remote SCADA software.
PAGE 10
 Built-in Dual Watchdog The Dual Watchdog consists of a Module Watchdog and a Host Watchdog. Module Watchdog is a built-in hardware circuit that can be used to monitor the operation of the module and will reset the CPU module if a failure occurs in the hardware or the software. Host Watchdog is a software function that can be used to monitor the operating status of the host, and is used to prevent network communication problems or host failures.

Chapter 4. Modbus Applications The PET-7000/ET-7000 is a Modbus device that allows you to access terminals data via Ethernet and communicates using a master-slave technique in which only one device (the master) can initiate transactions (called queries). The other devices (slaves) respond by supplying the requested data to the master, or by taking the action requested in the query.
PAGE 71
4.1. What is Modbus TCP/IP? Modbus is a communication protocol developed by Modicon in 1979. Different versions of Modbus used today include Modbus RTU (based on serial communication like RS485 and RS232), Modbus ASCII and Modbus TCP, which is the Modbus RTU protocol embedded into TCP packets. Modbus TCP is an internet protocol. The protocol embeds a Modbus frame into a TCP frame so that a connection oriented approach is obtained thereby making it reliable.
PAGE 72
4.2. Modbus Message Structure Modbus devices communicate using a master-slave (client-server) technique in which only one device (the master/client) can initiate transactions (called queries). The other devices (slaves/servers) respond by supplying the requested data to the master, or by taking the action requested in the query. A master‟s query will consist of a slave address (or broadcast address), a function code defining the requested action, any required data, and an error checking field.
PAGE 73
4.2.1. Address The first byte of information in the message structure of Modbus is the receiver‟s address. The valid addresses are in the range of 0 to 247. Addresses from 1 to 247 are given to individual Modbus devices and 0 is used for broadcast. Reference Description 0xxxx Read/Write Discrete Outputs or Coils. A 0x reference address is used to device output data to a digital output channel. 1xxxx Read Discrete Inputs.
PAGE 74
4.2.2. Function Codes The second byte in the frame structure is the function code. The function code describes what the slave is required to do. Valid function codes are between 1 and 255. The slave uses the same function code as the request to answer it. Only when error occurs in the system, the highest bit of the function code will be made „1‟. Hence the master will know if the message has been transmitted correctly or not.

Appendix A. Frame Ground Electronic circuits are constantly vulnerable to Electro-Static Discharge (ESD), which become worse in a continental climate area. PET-7000/ET-7000 series modules feature a new design for the frame ground, which provides a path for bypassing ESD, allowing enhanced static protection (ESD) capability and ensures that the module is more reliable.

Appendix B. Node Information Area Each PET-7000/ET-7000 module has a built-in EEPROM to store configuration information such as IP address, type code, etc. One minor drawback is that there are no visual indications of the configuration of the module. New PET-7000/ET-7000 modules include node information areas that are protected by a cover, as shown below, and can be used to make a written record of the node information, such as IP address, etc.

Appendix C. Modbus Application Notes C.1. Dual Watchdog Dual Watchdog consists of Module Watchdog and Host Watchdog. 1. The Module Watchdog is a built-in hardware circuit that will reset the CPU module if a failure occurs in either the hardware or the software. If the application does not refresh the watchdog timer within 0.8 seconds, the watchdog circuit will initiate a reset of the CPU. 2. The Host Watchdog is a software function that can be used to monitor the operating status of the host.
PAGE 111
C.2. Power ON Value If the ET-7000/PET-7000 series module is reset, the output of the module is set to the predefined Power ON Value for the DO and AO channels. DO address 00435 of the ET-7000/PET-7000 series Modbus register is the first address of the Power ON value, and the total number of channels depend on the type of module. For example: Addresses 00435 to 00438 records the Power ON value for the 4-Channel ET-7017/PET-7017.
PAGE 112
C.3. Safe Value If the time of the Host PC losing Modbus/TCP communication with the module is greater than the host WatchDog timer setting (called WDT timeout), the output of the Digital and Analog channels is set to the Safe Value, and the count of the host WDT events is increased by one. AO address 40558 is the address of the Host WDT events. The value of the WDT events will be not stored into EEPROM, and will return to 0 after the module is rebooted.
PAGE 113
Click the ON/OFF radio box to set the Safe value and then click the to enable the settings to take effect. button C.4. AI High/Low Alarm ET-7017/PET-7017 and ET-7017-10 module equip with the High/Low Alarm function. When the alarm function is enabled, the specified registers are the alarm indicator. The alarm function is to compare the analog input value with given high alarm value and low alarm value. Address 00636 to 00667 can be used to enable/disable the AI High Alarm function.
PAGE 114
Address 40296 to 40327 records the High Alarm value. Address 40328 to 40359 records the Low Alarm value. By the default, the High Alarm value is 32767 and the Low Alarm value is -32768.
PAGE 115
The analog input High/Low Alarm contains two alarm types, Momentary Alarm and Latch Alarm. Address 00700 of Modbus register can be used to set the High Alarm type of channel 0 and the total number of channels depends on the type of module. Address 00732 of Modbus register can be used to set the Low Alarm type of channel 0.
PAGE 116
 Momentary Alarm The alarm status is cleared while the analog input is not exceeding the alarm value. For example: If analog input value of channel 0 (30001) > High Alarm value (40296), the address 00764 is 1, else it is 0. If analog input Value of channel 0 (30001) < Low Alarm value (40328), the address 00796 is 1, else it is 0. The address 00764 to 00795 is the High alarm indicator. If a High alarm occurred, the value of register is 1. In normal condition, it will be 0.
