Ethernet IO module assists industrial robots
Industrial robots are multi joint robotic arms or multi degree of freedom machine devices aimed at the industrial field, which can achieve many material distribution, retrieval, pallets, and so on in industrial sites. However, due to the fact that many industrial six axes are equipped with 32 IO ports as standard, the IO ports are not sufficient in practical applications. Therefore, some DIN and DO extensions can be met through IO modules.
MQTT Ethernet IO Remote Module4701X Safety Instrumented System (SIS)
The Modbus TCP Ethernet IO module has multiple channels, such as 4-way, 8-way, and 16-way switch input and output options. The communication protocol of the Ethernet IO module adopts the standard Modbus TCP protocol, Modbus RTU over TCP protocol, and MQTT protocol. Can support LAN configuration, with 1 DC power output to other devices on site, reducing the difficulty and cost of on-site wiring.
Most of the MQTT Ethernet IO modules should collect some IO port information and transmit data through the network port. In fact, the Ethernet IO module can not only serve as a TCP server, but also as a TCP client. In addition, it can not only count high-speed pulses but also output high-4701X Safety Instrumented System (SIS)speed pulses. This is very convenient for doing some control processing on industrial sites, such as controlling servo motors and other scenarios! The most important thing is the data caching function. Even if the network is disconnected, it is not afraid. The data will be automatically cached, and after the network is restored, it will be automatically retransmitted.
The MxxxT industrial remote Ethernet I/O data acquisition module is embedded with a 32-bit high-performance microprocessor MCU, and integrates an industrial grade 10/100M adaptive Ethernet interface to support the standard Modbus protocol. It can easily integrate with third-party SCADA software, PLC, and HMI devices for application. Equipped with an RS485 interface, it has good scalability and can be cascaded with standard Modbus RTU I/O devices through the RS485 bus to achieve the combination of various digital, analog, and thermal resistance IO modules, saving costs. At the same time, this device has the function of cluster register mapping, and the data of the cluster is automatically collected into the mapping storage area of the local computer. The upper computer can respond quickly without waiting when querying, meeting the strict and timely functional requirements of industrial sites.
What is a remote IO module and what are its purposes
Technology is constantly evolving, and we can come into contact with various electronic devices both in daily life and in the workplace. And a large number of electronic devices work together to generate some signal sources. In order to better transmit and collect signals, industrial control products such as remote IO modules, signal transmitters, and signal acquisition modules have been developed.
In the past, people had to connect existing lines and boxes one at a time, which greatly increased the cost and construction time of cables. Moreover, if the distance was too long, they also had to face issues such as voltage attenuation. And through the remote IO module, this problem can be effectively solved.
If your cabinet is 200 meters away from the site and remote IO is not used, then you can extend each signal line by 200 meters and install the remote IO module on site, which can save you a lot of cable costs and reduce the complexity of construction.
In short, sometimes some IOs are set far away from the central control room and then connected back to the central control room through fiber optics to save on cable procurement and construction. Sometimes, the logical “remote” is because the allowed quantity of “local IO” cannot meet the actual needs, so it is necessary to connect to the “remote IO template”, which depends on the situation.
In addition, the general cabinet is placed on the equipment site. However, some control signals, such as emergency stop and bypass, are implemented in the control room, so remote IO modules need to be used to transmit these signals to the control system in the computer room.
What is an Ethernet IO module and what are its functions
The Ethernet IO module is a hardware gateway that adds IO to the network port.
The Ethernet IO module has hardware interfaces such as switches, analog signals, relays, RS485, RJ45, etc. Can be used for IO data collection network port transmission in industrial automation. Simply put, it refers to sensors with standard signals on site, or serial devices with 485 signals such as PLCs, which can be converted into real values through such gateways and then transmitted to the host for display through network ports.

Application Scheme of Industrial Ethernet Remote IO Module in Intelligent Manufacturing Workshop
With the advent of Industry 4.0, intelligent manufacturing has become a trend in industrial production. Intelligent manufacturing requires efficient, stable, and reliable industrial Ethernet remote IO modules to monitor the production process. This article will share an application case of an intelligent manufacturing workshop based on industrial Ethernet remote IO module.4701X Safety Instrumented System (SIS)
The production process of this intelligent manufacturing workshop is mainly divided into two parts: injection molding and automated assembly. The injection molding process requires controlling parameters such as the melting temperature of the melt, the speed and pressure of the injection molding machine. The automated assembly process requires controlling the actions of the assembly robot and detecting the quality of the product. In addition to these production process data, there are also equipment production data such as daily and weekly production in the workshop, as well as equipment status data such as operation, manual, automatic, mold adjustment, and alarm.
In the past, the production process of the factory mainly relied on traditional hard wiring to control the production process, resulting in low work efficiency due to the need for frequent replacement of transmission lines to meet production needs. Moreover, it is very difficult to collect a large number of types of detection and monitoring data for intelligent manufacturing. In order to improve efficiency, production quality, and reliability, the factory has introduced the industrial Ethernet remote IO module MxxT using barium rhenium technology.
The injection molding machine itself comes with MODBUS industrial control bus data or basic status signal output. The barium rhenium technology remote IO module collects data from the device interface RS232/RS485 port, collects status information of the injection molding machine such as startup, operation, and pause, and uploads it to the injection molding machine controller, or wirelessly uploads it to the cloud server. Based on devices, according to the communication protocols and interfaces of different devices, data is obtained by calling their interface channels, and then transmitted to the server.
The remote IO module is connected to the controller of the injection molding machine, and the operation data of the injection molding machine is uploaded and distributed wirelessly, achieving remote monitoring and intelligent control of the injection molding machine. In addition, the remote I/O module supports perceptual access to peripheral devices such as mold temperature machines, cutting machines, and dryers for injection molding machines, providing users with smart factory services.
During the injection molding process, the industrial Ethernet remote IO module transmits real-4701X Safety Instrumented System (SIS)time data such as temperature, pressure, and speed to the main controller for monitoring and adjustment, ensuring the stability and compliance of production parameters under different conditions. In the automated assembly process, the industrial Ethernet remote IO module collects data through sensors and other devices, and transmits the relevant data to the main controller for adjustment of relevant actions. For example, the industrial Ethernet remote IO module can monitor the actions of assembly robots, detect the accuracy of product assembly and product quality, and ensure the production quality and stability of the product. At the same time, all production data can also be collected and analyzed remotely, helping enterprise managers better monitor production efficiency and quality.
By introducing industrial Ethernet remote IO modules, this intelligent manufacturing workshop not only improves production efficiency and stability, but also reduces labor and energy costs. Because the industrial Ethernet remote IO module can help enterprises complete the collection and monitoring of production data with one click, as well as avoid unnecessary line replacement and the need for workers to enter and exit the production process, thereby reducing costs and improving production efficiency for enterprises.
In summary, the application of industrial Ethernet remote IO modules in intelligent manufacturing workshops not only improves production efficiency and quality, reduces costs, but also achieves intelligent and digital management of production processes, bringing more opportunities and development space for enterprise development.
In addition, this device is widely used for networking and data collection of industrial equipment such as injection molding machines, air compressors, CNC machine tools, on-site PLCs, instruments, sensors, CNC, and electromechanical equipment.
Building a High Channel Density Digital IO Module for the Next Generation Industrial Automation Controller
There are currently many articles introducing Industry 4.0, and smart sensors are becoming increasingly popular in factory environments (I and other authors have written about these topics). Although we have all noticed a significant increase in the use of sensors in factories, processing plants, and even some newly built automation systems, the widespread use of sensors has also brought about an important change, which is the need to handle a large amount of IO within these old controllers. These IOs may be digital or analog. This requires the construction of high-density IO modules with size and heat limitations. In this article, I will focus on digital IO, and in subsequent articles, I will introduce analog IO.
Usually, digital IO in PLC consists of discrete devices such as resistors/capacitors or independent FET drives. In order to minimize the size of the controller as much as possible and to handle 2 to 4 times the number of channels, this has led to a shift from a separate approach to an integrated approach.
We can use the entire article to illustrate the drawbacks of the split method, especially when the number of channels processed by each module reaches 8 or more. However, when it comes to high heat/power consumption, a large number of split components (from the perspective of size and mean time between failures (MTBF)), and the need for reliable system specifications, it is sufficient to demonstrate that the split method is not feasible.
Figure 1 shows the technical challenges faced in building high-density digital input (DI) and digital output (DO) modules. In both Di and DO systems, size and heat dissipation issues need to be considered.

For digital input, it is also important to note that it supports different input types, including 1/2/3 type inputs, and in some cases, 24V and 48V inputs. In all cases, reliable operating characteristics are crucial, and sometimes circuit detection is also crucial.
For digital outputs, the system uses different FET configurations to drive the load. The accuracy of the driving current is usually an important consideration. In many cases, diagnosis is also very important.
We will explore how integrated solutions can help address some of these challenges.
Design a High Channel Density Digital Input Module
The traditional split design uses a resistive voltage divider network to convert 24V/48V signals into signals that can be used by microcontrollers. The front-end can also use discrete RC filters. If isolation is required, external optocouplers are sometimes used.
Figure 1 shows a typical discrete method for constructing digital input circuits.
Figure 1. Considerations for digital input and output modules.
This type of design is suitable for a certain number of digital inputs; 4 to 8 per board. Beyond this number, this design will soon become impractical. This separation scheme can bring various problems, including:
High power consumption and related board high temperature points.
Each channel requires an optocoupler.
Excessive components can lead to low FIT rate and even require larger devices.
More importantly, the split design method means that the input current increases linearly with the input voltage. Assuming a 2.2K Ω input resistor and 24V V is used. When the input is 1, for example, at 24V, the input current is 11mA, which is equivalent to a power consumption of 264mW. The power consumption of the 8-channel module is greater than 2W, and the power consumption of the 32-bit module is greater than 8W. Refer to Figure 3 below
From a cooling perspective alone, this split design cannot support multiple channels on a single board.
One of the biggest advantages of integrated digital input design is the significant reduction in power consumption, thereby reducing heat dissipation. Most integrated digital input devices allow configurable input current limitations to significantly reduce power consumption.
When the current limiting value is set to 2.6mA, the power consumption is significantly reduced, with each channel approximately 60mW. The rated value of the 8-channel digital input module can now be set below 0.5
Another reason for opposing the use of split logic design is that sometimes DI modules must support different types of inputs. The standard 24V digital input specifications published by IEC are divided into Type 1, Type 2, and Type 3. Type 1 and Type 3 are usually used in combination because their current and threshold limits are very similar. Type 2 has a current limit of 6mA, which is higher. When using the split method, it may be necessary to redesign as most discrete values need to be updated.
However, integrated digital input products typically support all three types. Essentially, Type 1 and Type 3 are generally supported by integrated digital input devices. However, in order to meet the minimum current requirement of 6mA for Type 2 input, we need to use two channels in parallel for one field input. And only adjust the current limiting resistance. This requires a circuit board change, but the change is minimal.

Therefore, barium rhenium technology remote IO modules are widely used in industrial IoT, such as intelligent real estate, intelligent campus, intelligent factory, intelligent transportation, intelligent water conservancy, intelligent agriculture, intelligent campus, intelligent community, intelligent transportation, and many other industries.
What is the role of distributed IO modules and what are their main applications in
The distributed IO module transmits status signals from the measurement and control field to various measurement and control fields for control. It is mainly used in the industrial field and can also be used for detection of equipment such as air conditioners and motors.
In distributed systems, there are important business data closely related to system operation, as well as data related to nodes, application services, and data services, which are crucial for the normal operation of clusters.
IO on general PLCs is usually closely followed by CPU units, but in order to facilitate connection and maintenance, the concept of distributed IO has been proposed in the industrial field. That is to say, the IO unit can be arranged far away from the PLC CPU unit and communicate through the network communication protocol of the device layer.
The distributed IO module is developed for detecting and implementing remote control of various types of standard analog and switch signals (frequency, pulse, or switch state signals) in the field of measurement and control. The series of modules can digitize the test signal front-end and transmit it to the host through optical fiber; Or transmit the control instructions sent by the host to the controlled device to achieve remote control. Especially suitable for state detection and control of complex electromagnetic environments in power, industrial control, on-site switchgear, and large power equipment.
