1.1.3

Comparison of PETL/tET/tPET Module

The tPET and PETL-7060 series features true IEEE 802.3af-compliant (classification, Class 1) Power over Ethernet (PoE) functions. Now, not only can data be carried through an Ethernet cable, but power can also be provided. This feature makes installation of tPET series modules a straightforward task. Imagine no more unnecessary wires with only an Ethernet cable required in order to take care of everything in the field. The tET/tPET and PETL-7060 series also features a built-in web server that allows basic configuration, I/O monitoring and I/O control to be performed by simply using a web browser meaning that remote control of your modules is as easy as surfing the Internet. In addition, tET/tPET and PETL-7060 series modules support the Modbus TCP/UDP protocols, ensuring perfect integration with SCADA software.

Industrial PoE Solutions

When using PoE devices such as the tPET series, you can incorporate the ICP DAS

“PoE”

switch, the

“NS-205PSE”

, as the power source. The NS-205PSE automatically detects any connected devices, whether they are PoE devices or not. This mechanism ensures that the NS-205PSE will function simultaneously with both PoE and non-PoE devices.

Note that when acting as a power source for a PoE device, the NS-205PSE requires a power input ranging from +46 V DC to +55 V DC .

ICP DAS CO., LTD.



More Information

All tET series modules can only be powered using a+12 V DC to +48 V DC power supply connected through a removable terminal block. In contrast, tPET and PETL-7060 series modules offer two methods of supplying power. The first is through the Ethernet via a PoE switch; the second is through a removable terminal block via an external power source. The external power supply should be in the range of +12 V the PoE switch or not. DC to 48 V DC . The reason for including the second method is to provide a redundant power input feature. tPET and PETL-7060 series modules also indicate an LED that indicates whether the power is being supplied by CPU Ethernet Modbus TCP/UDP Web Configuration Web HMI Multi-client IP Filter Latched DI DI as Counter Frequency Measurement tPET 32-bit, 3.5 kHz PETL-7060 32-bit ARM 10/100 M, PoE Yes Yes Simplified Yes (Max.

Features



Built-in Web Server

Each tET/tPET/PETL series module contains a built-in web server that allows users to easily configure, monitor and control the module from a remote location using a web browser. 

Modbus Protocol

The Modbus TCP/UDP slave function on the Ethernet port can be used to provide data to remote SCADA software. 

All-in-one Module

A variety of I/O components are available on multiple channels in a single module, which provides the most cost effective I/O usage and enhances the performance of I/O operations. 

Automatic MDI/MDI-X Detection for Plug-and-Play

The RJ-45 port supports automatic sensing of MDI/MDI-x switching that can automatically detect the type of connection being used by the Ethernet device without requiring special straight or crossover cables. 

Built-in Dual Watchdog

The Dual Watchdog consists of a CPU Watchdog (for hardware functions) and a Host Watchdog (for software functions). The

CPU Watchdog

will automatically reset it-self if the built-in firmware encounters an abnormal situation. If there is no communication between the module and the host (PC or PLC) for a specified period of time (i.e., the Watchdog timeout), the

Host Watchdog

will set the digital output based on a predefined safe-value. ICP DAS CO., LTD.


Ethernet I/O Modules 

Built-in Multi-Function I/O

All

Digital Output

modules provide:  A

Power-on Value

(On boot up, the digital output value is set as the Power-on value)   A

Safe Value

(If Modbus TCP communication is lost for a certain period, the digital output Value will be set as the user-defined safe value)

A PWM Function

: The digital output channels on PETL/tET/tPET series include a PWM (pulse generation) function that can be used to set different frequencies (50 or 100 Hz Max.) and duty cycles for each digital output channel. In addition, the two digital output channels can work either independently or simultaneously. The term “High Duty Cycle” describes the duration of 'on' time in proportion to the regular interval or 'period' of time. Similarly, the term “Low Duty Cycle” corresponds to the duration of the 'off' time. Consequently, it is not necessary to keep switching from ON to OFF from remote a controller. In this way, the tET/tPET/PETL series module reduces the complexity required for the control system and enhances timing accuracy. All

Digital Input

modules provide:   

Digital input channels that can also be used as 32-bit high speed (3.5 kHz) counters. High/Low Latched Status Commands:

in the figure.

The modules provide commands to read the status of any digital input channels that are latched high or latched low. The following is an example that shows the usefulness of the latched digital input. If we wish to read a key stroke from a key switch connected to the digital input channel of a module, the input signal of the key stroke is a pulse signal as shown If we just use the read digital input status command to read the signal and we cannot send the command during the B period due to some reasons, then we will lose the key stroke information. However, with the read latched digital input command, we can still get the key stroke information even we are not able to send command in B period.

Frequency Measurement

: tET/tPET/PETL series modules also provide a frequency measurement function that retrieves the digital input counter value at specific times and calculates the frequency. Rather than polling via a remote host, the tET/tPET/PETL series modules can determine the frequency directly, reducing the communication delay caused by two ends and also improves the accuracy of the frequency measurement. In order to applying for more applications, this module provides 3 scan modes and 4 moving average methods for user to select the best way in their applications. ICP DAS CO., LTD.



I/O Pair-Connection

The I/O Pair-connection function is used to create a digital input to digital output pair through the Ethernet. Once the configuration is complete, the PETL/tET/tPET series modules can continuously poll the status of a remote digital input device using the Modbus TCP protocol, and then write to the local digital output channels in the background.

I/O Pair Connection Applications

The PETL/tET/tPET series modules can be used to create DI-to-DO pair connections via the Ethernet. Once the configuration is complete, the modules can then poll the status of the local DI channels and then use the Modbus/TCP protocol to continuously write to a remote DO device in the background. This is useful when connecting digital I/O devices that do not themselves have Ethernet capability. The following will describe how to correctly configure the I/O pair connection function.

5.1 One Module Polling the Remote DI/DO (1-to-1, Polling Mode)

Step 1: Connect the device to a Network, a PC and a Power supply.

Confirm that the PETL/tET/tPET series modules are functioning correctly. Refer to Chapter 3. “Getting Started” for more details. An example configuration shown below:

Note that tPET-P2POR2 and tPET-PD2POR2 modules are used in this example.

Modbus Information

The PETL/tET/tPET series is a family of IP-based Modbus I/O devices that allow you to remotely control DI/DO terminals via an Ethernet connection and uses a master-slave communication technique in which only one device (the master) can initiate a transaction (called queries), while other devices (slaves) respond by either supplying the requested data to the master, or by taking the action requested in the query. Most SCADA (Supervisory Control and Data Acquisition) and HMI software, such as Citect (Schneider Electric), ICONICS, iFIX, InduSoft, Intouch, Entivity Studio, Entivity Live, Entivity VLC, Trace Mode, Wizcon (ElUTIONS), and Wonderware, etc. can be used to easily integrate serial devices via the Modbus protocol. Modbus/TCP master applications can also be developed using any programming language, such as VB, C# and so on. ICP DAS provides the Modbus SDK that allows development of Modbus applications on a PC. The relevant demo programs and SDK can be obtained from the following locations: VB Demo ： http://ftp.icpdas.com/pub/cd/6000cd/napdos/et7000/demo/pc_client/ .Net demo and SDK ： http://ftp.icpdas.com/pub/cd/8000cd/napdos/modbus/nmodbus/ ICP DAS CO., LTD.



6.1 What is Modbus TCP/IP?

Modbus is a communication protocol that was developed by Modicon Inc. in 1979, and was originally designed for use with Modicon controllers. Detailed information regarding the Modbus protocol can be found at: http://www.modbus.org

. The different versions of the Modbus protocol used today include Modbus RTU, which is based on serial communication interfaces such as RS-485 and RS-232, Modbus ASCII and Modbus TCP, which uses 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 more reliable. The master queries the slave and the slave responds with a reply. The protocol is open and, hence, highly scalable.

6.2 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 either supplying the requested data to the master, or by taking the action requested in the query. A query from a master will consist of a slave address (or broadcast address), a function code defining the requested action, any required data, and an error checking field. A response from a slave consists of fields confirming the action taken, any data to be returned, and an error checking field. 

1. Net ID (Station Number)

The first byte in the frame structure of a Modbus RTU query is the receiver’s address. Availed address is in the range of 0 to 247. Address 0 is used for general broadcast, while addresses 1 to 247 are given to individual Modbus devices.

2. Function Code

The second byte in the frame structure of a Modbus RTU query is the function code, which describes what the slave device is required to do. Valid function codes are between 1 and 255. To answer the query, the slave device uses the same function code as contained in the request. The highest bit of the function code will only be set to ‘1’ if an error occurs in the system. In this way, the master will know whether the message has been transmitted correctly or not.

3. Data Field

Data is transmitted in 8-, 16- and 32-bit format. The data for 16-bit registers is transmitted in high-byte first format. For example: 0x0A0B ==> 0x0A, 0x0B. The data for 32-bit registers is transmitted as two 16-bit registers, and is low-word first. For example: 0x0A0B0C0D ==> 0x0C, 0x0D, 0x0A, 0x0B. The data field of messages sent between a master and a slave contains additional information about the action to be taken by the master or any information requested by the slave. If the master does not require this information, the data field can be empty.

Reference (Address) Description 0xxxx Read/Write Discrete Outputs or Coils.

A 0x reference address is used to output device data to a digital output channel.

1xxxx Read Discrete Inputs.

The ON/OFF status of a 1x reference address is controlled by the corresponding digital input channel.

3xxxx Read Input Registers.

A 3x reference register contains a 16-bit number received from an external source, e.g. an analog signal.

4xxxx Read/Write Output or Holding Registers.

A 4x register is used to store 16bits of numerical data (binary or decimal), or to send the data from the CPU to an output channel.

For more details regarding Address Mapping (Reference Number), refer to Section 6.3 “Modbus Register Table”.
