MQTT IoT Remote IO Module Based on Ethernet Communication Technology
Barium rhenium technology remote IO modules are widely used in IoT scenarios such as intelligent transportation, smart water conservancy, smart agriculture, smart campuses, smart communities, smart power distribution, and smart water conservancy.
With the development of IIOT industrial Internet of Things technology, more and more traditional assets need to be connected to the internet, achieving unified data collection and analysis, and breaking the phenomenon of traditional device information silos. The barium rhenium technology remote IO module M160T, which supports IoT protocols, has become an excellent choice for many enterprises to achieve device networking, remote control, and data collection based on the compatibility of existing devices and the accessibility of IoT platforms!
Ethernet communication technology is a mature communication technology because it has the characteristics of stability, reliability, mature technology, fast transmission speed, and fast construction wiring. Due to its wide application, Ethernet communication through the MQTT protocol is the main way for enterprise equipment to go to the cloud. Barium rhenium technology can quickly collect data and control such as air compressor room, property living pump room, street light control, liquid level collection, temperature and humidity collection through Ethernet remote IO module.3708EN Safety Instrumented System (SIS)
So, why is the remote IO module of barium rhenium technology widely used in the field of industrial IoT? The specific reasons are as follows.
1. Actively connect to cloud platforms:
Based on the characteristics of Ethernet communication networks, the barium rhenium technology remote IO module does not require complex settings such as peanut shells to achieve the Internet of Things. The barium rhenium technology remote IO module needs to support both TCP client and TCP server functions.
2. Compatibility with existing systems:
It supports TCP Server and Modbus TCP protocol functions, and is compatible with device access of traditional upper level systems or HMI TCP clients.
3. Support multiple IoT platforms:

Through the use of barium rhenium technology remote IO modules, there is no need to replace existing various enterprise assets, and the digital transition to the Internet of Things platform can be quickly achieved. 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.
The role of distributed IO modules:
1. Support 4-way switch digital quantity
2. Supports 8 analog inputs
3. 4 relay outputs, 1 RS485 serial port data acquisition to Ethernet
4. 485 to Ethernet serial server
5. Supports Modbus to TCP/UDP protocol conversion
6. Supports virtual serial ports and interfaces with various configuration software
7. Support 0-5V, 0-10V, 0-30V range acquisition
8. Supports 0-20ma and 4-20ma range acquisition
Definition of IO Link Protocol and Its Interface
IO Link is a peer-to-peer, serial digital communication protocol designed for periodic data exchange between sensors/actuators and controllers (PLCs). The IO Link protocol was first proposed by Siemens and has now become an international standard IEC 61131-9. With the advancement of Industry 4.0, the use of IO Link is becoming increasingly widespread. Today”s article will introduce the definition of the IO Link protocol and its interfaces.
Factory automation can be divided into execution layer, on-site layer, on-site control layer, workshop control layer, and management layer according to functional division. As shown in the following figure:
The execution layer includes various execution mechanisms (valves, pumps, motors, etc.) and sensors, which are the muscles and peripheral nerves of factory automation. They receive commands from the upper layer and complete specified actions.
The on-3708EN Safety Instrumented System (SIS) site layer includes various distributed IO3708EN Safety Instrumented System (SIS) systems, which are the central nervous system of factory automation. It conveys control instructions from the upper layer to the execution layer; And feedback the signals from the execution layer to the control layer, serving as the information center;
The on-site control layer includes various PLC systems, which are the brains of factory automation. It issues corresponding instructions and commands the execution layer to complete corresponding actions based on internal program requirements and signal feedback from the execution layer;
The workshop control layer (MES) and management layer communicate with various PLC systems at the management level to complete management tasks at the workshop and factory levels.
The IO Link protocol to be introduced in this article is a protocol that transfers data between the execution layer and the field layer. An IO Link system consists of the following components:
1) IO Link Master;
2) IO Link Device;
3) Non shielded 3-5 core standard cable;
4) Tools for configuring IO Link parameters;
The IO Link Master transfers data between the IO Link device and the PLC. It is usually a distributed IO module with IO Link connection channels on the module. The IO Link Device is connected to the channel of the IO Link Master through a cable, and the IO Link Master exchanges data with the PLC through a bus. As shown in the following figure:
Every IO Link device needs to be connected to a channel of the IO Link supervisor, so IO Link is a peer-to-peer communication protocol, not a bus protocol.
IO Link devices are divided into two types: sensors and actuators: sensors are usually the four pin interface of M12, and actuators are usually the five pin interface of M12.
According to IEC 60974-5-2, the definition of IO Link Device pins follows the following regulations:
1) Pin 1 (PIN1): 24V power supply positive pole;
2) Pin 3 (PIN3): 0V
3) Pin 4 (PIN4): IO Link communication or standard IO output;
The pin definition of the IO Link device is shown in the following figure:
Which types of equipment should PLC module manufacturers develop first?
We know that PLC, also known as programmable logic controller, collects variable data through various IOs to achieve the purpose of automated control. Therefore, developing PLC is largely about developing IO. However, with so many types of IO, which PLC module manufacturers should develop first? Let me share my opinion:
1. Digital input IO, including PNP and NPN digital input IO, counter input IO, etc.
2. Digital output IO, including PNP and NPN digital output IO, PWM pulse output IO, relay output IO, and so on.
3. Analog input IO, including current acquisition input IO, voltage acquisition input IO, temperature acquisition input IO, and so on. The current input IO can collect currents ranging from 0 to 20 milliamperes, while the voltage input IO can collect voltages ranging from negative 10V to positive 10V. Temperature acquisition IO includes thermocouples and thermal resistors.
4. The style of analog output IO is similar to that of analog input IO, but does not include temperature analog, mainly voltage and current type.
What are the types of integrated IO modules3708EN Safety Instrumented System (SIS)
For a programmable logic controller, IO fulfills the responsibilities of data acquisition and instruction output. What control objectives can a PLC achieve, and the quantity and type of IO are crucial. For general integrated PLCs, the number and types of IO interfaces are constant. Some friends may ask, what if you encounter a complex control project with insufficient IO ports in the PLC? Don”t worry, nowadays PLCs have communication interfaces that can be connected to other IO couplers to achieve IO expansion. So, what are the types of IO modules that we can integrate in our daily lives? Actually, it can be mainly divided into four categories, namely:
1. Digital signal acquisition IO can achieve discontinuous signal acquisition, and a typical IO type is a counter input IO module.

3. After discussing digital IO, let”s talk about analog IO. Firstly, analog input IO includes voltage analog input IO, current analog input IO, temperature analog input IO, etc. They collect continuous signals.
4. Finally, there is the output type IO of analog quantity, mainly including voltage analog quantity output type IO and current analog quantity output type IO. Some friends may ask why there is no temperature this time, but there are relatively few applications, mainly based on voltage and current types.3708EN Safety Instrumented System (SIS)
Industrial automation solutions, starting with remote IO modules!
The remote IO module is mainly used for collecting analog and digital signals on industrial sites, and can also output analog and digital signals to control equipment. It is possible to expand the input and output ports of data processing equipment such as PLCs and collection instruments. For example, a PLC only has 10 analog input interfaces, but if 30 analog quantities need to be collected on site, remote IO expansion needs to be added.
Furthermore, due to the distance between the equipment and the main control PLC or industrial computer, RS-485 bus is usually used for transmission. There are also some factories with high levels of automation that use industrial Ethernet to control remote IO modules. In the past, when laying lines between equipment and cabinets, people had to connect them one by one, which greatly increased the cost of cables and construction time. Moreover, if the distance was relatively long, they also faced problems such as voltage attenuation. And with the remote IO module, it effectively solves this problem. If your cabinet is 200 meters away from the site and you do not use remote IO, then you need to lay out each signal line for 200 meters. Installing the remote IO module on site can save you a lot of cable costs and reduce the complexity of construction from a cost perspective.
Simply put, sometimes some IO is set up in the on-site device cluster, which can be connected to the PLC through a communication cable to send the signal to any place where it is needed, saving wiring and PLC”s own IO points. Sometimes, the logical “remote” is because the allowed number of “local IO” cannot meet the actual needs, and it needs to be connected to the “remote IO template”, depending on the actual situation.
In addition, the general cabinet room is located on the device site. But some control signals, such as emergency stop and bypass, are implemented in the control room, so remote IO modules need to be used to send these signals to the control system in the cabinet room.
Why use remote I/O?
1. Because in some industrial applications, it is impossible to install PLCs with local I/O modules near on-site equipment due to harsh environments.
2. When you want to place the I/O module near the field device to eliminate long multi-core cables, you can receive signals from distant sensors and send remote control signals to control valves, motors, and other final actuators. The signal can be transmitted at any distance using various transmission protocols such as Ethernet and Profibus through high-speed media such as twisted pair and fiber optic.
3. Multiple transmission protocols such as Ethernet and Profibus can be used to send signals at any distance on high-speed media such as twisted pair and fiber optic.
The barium rhenium technology MXXT remote IO module uses industrial grade components with a wide working voltage of DC9-36V, which can operate normally within the range of -20~70 ℃. It supports RS485/232 communication mode, and the communication protocol adopts standard Modbus TCP protocol, Modbus RTU over TCP protocol, and MQTT protocol. We strive to fully meet the needs of our customers with an electrical and mechanical system that is anti-interference, resistant to harsh environments, and compatible with general use. It has stable performance, reliable quality, short delivery time, and fast response.
