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 Module3664 TRICONEX controller
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-3664 TRICONEX controllerspeed 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.

What are the characteristics of a demonstration system based on IO Link slave stations
IO Link is an industrial communication interface that is independent of any fieldbus and suitable for simple sensors and actuators at the lowest level of industrial control. The IO Link system includes IO Link devices (such as sensors and actuators), IO Link master stations, and cables for standard sensors. The system structure is shown in Figure 1. For example, when a remote IO module compatible with EtherNet/IP serves as the master station, in addition to standard I/O signals, the module sends and receives configuration data, diagnostic data, or enhanced process data through a pulse modulation process, which is then packaged into EtherNet/IP data packets and finally transmitted to the network master station, usually a PLC. In the above applications, the connection between remote I/O and IO Link devices remains the same as that of traditional discrete devices. The advantage of IO Link mainly lies in its greater information exchange capability, which was previously impossible to achieve with standard I/O devices. Another advantage of IO Link is that it does not rely on any fieldbus, and through any I/O module that complies with the IO Link protocol (including local I/O and remote I/O), IO Link sensors or actuators can be integrated into any fieldbus system.
In order to further study the architecture, communication mechanism, and development application of the IO Link system, an IO Link slave toolkit can be designed and developed, including a universal development module for IO Link, an IO Link analysis tool, and an IO Link slave protocol stack. The IO Link universal development module is the foundation for this work and also serves as a bridge between the IO Link master station and equipment signals. The IO Link analysis tool can help developers and testers analyze communication details to identify and solve problems. The IO Link slave protocol stack is a firmware library that provides a hardware abstraction layer and application program interface, allowing developers to easily and quickly develop IO Link slave products on various microprocessor platforms. The IO Link slave station studied in this article only focuses on digital (button) signal input and digital signal output (indicator light). The design of the IO Link universal development module only needs to be expanded on this basis to have the ability to process analog signals.
The IO Link Master module used in this article, USB IO Link Master, can connect IO Link devices to a PC, which can be configured and tested through the IO Link Device Tool software or demonstrated device functionality. IO Link devices must be described through a device description file (IODD file), which includes a set of XML text files and PNG graphic files, which contain information about device identification, communication characteristics, parameters, process data, and diagnostic data. The portion within the elliptical dashed line in Figure 2 is an IO Link three wire cable, with L+/I – being a 24 V DC power supply and C/Q being a signal line used to transmit process data, diagnostic data, configuration data, etc. The IO Link universal development module is mainly composed of data transceivers and microprocessors. It can process input signals from sensors and transmit information to the IO Link master station. It can also receive and process data information from the master station and transmit it to the actuator. The IO Link analysis tool can help developers view, record, analyze data, and understand communication details. This part of the design is not discussed in this article.
Introduction to IO Link Communication Mode3664 TRICONEX controller
IO Link devices can operate in SIO mode (standard I/O mode) or IO Link mode (communication mode). After power on, the device always operates in SIO mode. The port of the main station has different configuration methods. If configured in SIO mode, the main station considers the port as a standard digital input. If configured in communication mode, the main station will automatically identify the communicable devices for communication.
2.1 Data Types3664 TRICONEX controller
The three basic data types for IO Link communication are periodic data (or process data PD), non periodic data (or service data SD), and event.
The process data (PD) of the device is transmitted periodically in the form of a data frame, while service data (SD) is only exchanged after the master station issues a request. Figure 3 shows a typical IO Link message structure. When an event occurs, the “event flag” of the device is set, and the main station reads the reported event (service data cannot be exchanged during the reading process) upon detecting the setting. Therefore, events such as pollution, overheating, short circuits, or device status can be transmitted to the PLC or visualization software through the main station
2.2 Parameter data exchange
Since service data (SD) must be transmitted through PLC requests, SPDU (Service Protocol Data Unit) is defined. In the main station, requests for read and write services are written to SPDU and transmitted to devices through the IO Link interface.
The general structure of SPDU is shown in Figure 4, and its arrangement order is consistent with the transmission order. The elements in SPDU can take different forms depending on the type of service. SPDU allows access to data objects that are intended for transmission, while Index is used to specify the address of the requested data object on the remote IO Link device. In IO Link, there is a term called direct parameter page, which stores parameter information such as minimum cycle time, supplier ID, and master station commands. The data objects accessible in the direct parameter page can be selectively provided through SPDU.
HMT7742 is an IO Link slave transceiver chip that serves as a bridge between the MCU of external sensors or actuators and the 24V signal line that supports IO Link communication. When the IO Link device is connected to the master station, the master station initializes communication and exchanges data with the MCU. HMT7742 serves as the physical layer for communication.
Due to the fact that the three indicator lights (rated voltage 24 V) controlled by the output port of the MCU are powered by the IO Link power cord, it is necessary to monitor the current on the power cord in order to trigger appropriate corrective measures when the current exceeds a set threshold, such as removing the indicator lights from the IO Link power cord. The current monitoring module uses an INA194 current detection amplifier. As a high detection current detector, INA194 is directly connected to the power supply and can detect all downstream faults. It has a very high common mode rejection ratio, as well as a large bandwidth and response speed. It can amplify the voltage on the induction resistor 5O times and output it to the forward input terminal AIN0 of the MCU internal voltage comparator. When the voltage value of AIN0 exceeds the threshold set at the reverse input terminal, By controlling the low level output of PB0, the indicator LAMP can be cut off from the IO Link power line to achieve overcurrent protection function. This part of the circuit is shown in Figure 6.
