1Introduction
The tET/tPET series of devices are Ethernet I/O monitoring and control modules that provide the
networking ability and a variety of I/O functions. The modules can be remotely controlled through
a 10/100M Ethernet network using the Modbus TCP/UDP protocol. Modbus has become a de facto
standard communication, and is now the most commonly available means of connecting industrial
electronic devices. This makes the tET/tPET series perfect for integration with HMI, SCADA, PLC and
other software systems.

1.1.3 Comparison of tET/tPET Module
The tPET 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 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 series modules
support the Modbus TCP/UDP, MQTT, or SNMP protocols, ensuring perfect integration with HMI,
SCADA, PLC, or other 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 VDC to +55 VDC.

Ethernet I/O Modules
ICP DAS CO., LTD. tET/tPET IO Series User Manual, Ver. 2.4, Sep. 2023, P11
More Information for tET/tPET Series Modules
All tET series modules can only be powered using a +12 VDC to +48 VDC power supply connected
through a removable terminal block.
In contrast, tPET 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 VDC to 48 VDC. The reason for
including the second method is to provide a redundant power input feature. tPET series modules
also include an LED indicator that indicates whether the power is being supplied by the PoE switch
or not.

1.2 Features
Built-in Web Server
The tET/tPET series module can receive/send network
packets efficiently by using a 32-bit MCU. Web Server is
also built in to provide an intuitive web management
interface that allows users to easily configure, monitor and
control the module from a remote location using a web
browser.
Modbus TCP/UDP, MQTT, or SNMP Protocol
The Modbus TCP/UDP slave function on the Ethernet port can be used to provide data to remote
SCADA software. All AI/DI/DO modules of tET/ tPET series support the MQTT protocol. Only the
tPET-AD2 supports the SNMP V2c protocol by now.
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 the Auto-MDI/MDI-x feature to detect the type of the
connected Ethernet device and then automatically choose the MDI or MDIX
configuration. Thus, the user can use straight-through or crossover cables.

Ethernet I/O Modules
ICP DAS CO., LTD. tET/tPET IO Series User Manual, Ver. 2.4, Sep. 2023, P13
Built-in Multi-Function I/O
The DO modules support these functions:
Power-on Value: On boot up, the DO value will be set to the Power-on value.
Safe Value:
If Modbus TCP communication is lost for a specific period, the DO value will be set to the
user-defined safe value.
A PWM (Pulse-Width Modulation) Function:
Each of DO channel can be set to a different frequency (50 or 100 Hz Max.) and duty cycle,
also 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 module
reduces the complexity required for the control system and enhances timing accuracy.
Note: Because of the characteristics of the relay functions, it is recommended that the PWM
on modules with relay functions is not used for extended periods.
The DI modules support these functions:
Can be Used as a 32-bit High Speed Counter
High/Low Latched Status Commands:
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 in the figure.
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:
This function can be used to retrieve the digital input counter value at specific times and
calculates the frequency (Hz, Max. 3.5 kHz). Rather than polling via a remote host, the module
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.

Ethernet I/O Modules
ICP DAS CO., LTD. tET/tPET IO Series User Manual, Ver. 2.4, Sep. 2023, P14
Built-in Dual Watchdog
The Dual Watchdog function consists of a CPU Watchdog (for hardware
functions) and a Host Watchdog (for software functions).
CPU Watchdog:
The CPU Watchdog will automatically reset it-self if the built-in firmware
encounters an abnormal situation.
Host Watchdog
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.
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 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.

“Specification and Wiring”.
DC Power Input:
All tET/tPET series modules include “(R)+Vs” and “(B)GND” pins and are powered by a DC power
supply.
Frame Ground (F.G.):
Electronic circuits are constantly vulnerable to Electrostatic Discharge (ESD), which becomes
worse in a continental climate area. The tET/tPET series modules feature a new design for the
frame ground, which provides a path that bypasses ESD to prevent direct impact on hardware
from ESD and environmental interference, resulting in enhanced ESD protection capability
and ensuring that the module is more reliable.
