1.Automation gateway
Overview of Automation Gateway
Automation gateway is a protocol conversion gateway that enables interconnection and interoperability between various communication protocols PLC and various communication protocol field devices, in order to achieve PLC control over different protocol devices.
PLC various protocols, such as PROFINET, EtherNet/IP, MODBUS/TCP, EtherCAT, PROFIBUS
Various field equipment, such as frequency converters, MCCs, servos, etc
Various communication protocols for field equipment, such as MODBUS/RTU, CANOPEN, RS232/485 free protocol, CAN2.0 free protocol, MODBUS/TCP (S/C)
Technical performance characteristics
(1) High real-time requirements: Generally, gateway latency is required to be less than 10ms;
(2) High reliability requirements: Due to the working environment being at the bottom of the equipment, generally EMC ≥ level 3;
(3) Memory sharing type: Transparent protocol transmission generally cannot meet real-time requirements;
(4) Not much data: generally not exceeding 256 bytes;
Configuration of Automation Gateway
Considering reliability, real-time performance, and security, the automation gateway cannot be designed as a plug and play model and needs to be configured before application. The configuration of gateways can be divided into “PLC configuration mode” and “download configuration mode” for different customers and application scenarios.
PLC configuration mode: Use the electronic description files (GSD, GSDML, EDS, ESI) of the gateway to import PLC configuration software (STEP7, TIA, TwinCAT, Logix Designer, etc.), and configure the gateway and gateway downstream protocol in the PLC master station configuration software. This configuration method is designed for system engineers and is suitable for on-site implementation.
Download configuration mode: Use the DINGSHI gateway configuration software DSGConfi to configure the gateway (including downstream protocols) and form a configuration file, download it to the gateway and save it. This configuration method is aimed at OEM equipment development engineers.

5.2.2 PROFIBUS Hub PB-HUB
Product Function
The PROFIBUS hub PB-HUB can change the bus topology of the network to a tree or hybrid structure, while retaining the technical functions of the relay. The outstanding performance of PB-HUB is its branch (segmented) fault isolation function. If the A/B line on a certain branch (segment) is short circuited, open circuited, reversed, connected to the positive pole of the power supply, grounded, or damaged due to the DP interface of the station, causing the above faults on the A/B line, PBHUB can isolate the faults caused by this, and other branches can work as usual without being affected. During on-site debugging, different manufacturer sites can be divided into different sections and debugged separately at different times without affecting each other. Fault isolation and changing the bus structure are the most practical functions of BPB-HUB.
Product features
(1) No need for master station configuration: PB-HUB is a pure physical layer device, independent of the upper layer protocol, and does not require master station configuration or GSD files.
(2) Baud rate 9.6K-12M adaptive: No switch settings or any software configuration required.
(3) Regardless of the master/slave interface, terminal/non terminal nodes: the master/slave can be connected to any PROFIBUS interface of the PB-HUB. Each interface can serve as a terminal node or as a non terminal node.
(4) Transparent transmission in the physical layer is independent of the upper layer protocol: PB-HUB is independent of the upper layer protocol in the network; Therefore, it can be applied to all RS485 based PROFIBUS protocol functions, including PROFIBUS-DP/V0, V1, V2, and various application specifications, including PROFIsafe, Redundancy, and so on. It also supports connecting multiple master stations for communication, such as S7 FUSION protocol and Class II master station communication.
(5) Fault isolation function: Fault isolation between each branch interface; For example, if the A/B line on a certain branch (segment) is short circuited, open circuited, reversed, connected to the positive pole of the power supply, grounded, or damaged due to the DP interface at the station, the above faults and electromagnetic interference of the A/B line will not affect the operation of other interface segments.
(6) Scalable site and transmission length for cascade connection: Any interface segment can be further cascaded through PB-HUB; The number of concatenable connections is related to the baud rate. When the baud rate is less than 187.5K, the number of cascaded connections is 3 levels; When the baud rate is 500K~12M, the number of cascaded connections can reach 5 levels.
Product Usage
(1) Increase the number of sites, increase capacity, and extend transmission distance
Each interface of PB-HUB can independently drive a PROFIBUS segment, connect up to 31 stations, and extend the transmission distance to 1 kilometer at baud rates below 187.5K. PB-HUB can also achieve cascade connection. In this way, the hybrid PROFIBUS network structure composed of PB-HUB can have up to 126 sites, and the transmission distance can reach 3-4 kilometers based on the number of cascades. See Figure 6:
(2) Changing the PROFIBUS network topology
PB-HUB can be used to change the PROFIBUSDE bus topology and achieve tree and hybrid networks. See Figure 7.
(3) Isolation function: Each interface of PB-HUB can be expanded into a PROFIBUS segment, and electrical and fault isolation is achieved between each interface segment. Including: short circuit, open circuit, reverse connection, electromagnetic interference, it also has a repairing effect on the attenuation and distortion of communication waveforms. Figure 8: When DP1~DP3 all fail, DP4, DP5 (frequency converter), and DP6 (PLC) can still work normally.

5.3 Industrial Ethernet PROFINET switch
5.3.1 Product Overview
The application of industrial Ethernet technology is becoming increasingly common, and switches are essential products for industrial equipment networking. Compared with switches in the general IT field, industrial Ethernet switches need to meet the special requirements of industrial application sites, such as product stability, anti-interference ability, and support for specific industrial communication protocols. At present, most of the switches used by high-end users in the industrial control industry are foreign brands. The suppliers that have emerged in China in recent years were initially mainly used in information technology projects, with technology closer to the IT field. As a manufacturer of important industrial network components in China, DINGSHI’s products have long been recognized by users for their stable and reliable long-term operation on industrial sites. At the same time, DINGSHI is also a leading enterprise in the development and application of industrial Ethernet communication protocols, and switches have strong advantages in adapting to and supporting industrial communication protocols such as PROFINET. In summary, DINGSHI PN switches are a series of switches designed for industrial field applications, particularly suitable for the PROFINET communication protocol.
5.3.2 Product positioning and market requirements for PN switches
⑴. Industrial grade applications
Compared with switches in the IT industry, DINGSHI switches should have the ability to adapt to harsh industrial environments, including hardware indicators such as temperature, power supply, EMC level, and housing that meet the requirements for industrial use. This is a capability that ordinary IT industry switches do not possess.
⑵. Mainstream protocols supporting industrial equipment communication
As an expert in industrial fieldbus (industrial Ethernet) protocols, DINGSHI’s switches should have the ability to support multiple protocols, such as PROFINET, Ethernet IP, Modbus TCP, etc. This is DINGSHI’s expertise. DINGSHI switches have a targeted advantage in adapting to the characteristics of these industrial protocols, which is also a function that ordinary industrial switches find difficult to achieve.
⑶. Reasonable price
The product should be suitable for the purchasing power of general PROFINET protocol users, such as Siemens S7-1200 series PLC users. Due to the consideration of user equipment cost, the product price should not be too high. At present, the price of DINGSHI managed PN switches is the lowest among managed switches on the market.
(4). Possess commonly used management functions
The DINGSHI PN switch supports common management functions such as configuring MRP redundant ports, viewing and configuring port status information, and configuring QoS.
(5). Adapt to the operating habits of engineers in the industrial control industry
In addition to the packet forwarding and management functions of ordinary switches, DINGSHI switches were designed with the operational habits of industrial control industry engineers in mind. Taking PN switches as an example, by integrating the configuration and diagnostic information of the switches into GSDML files, the product can be loaded as a PN slave into the configuration software of the PN master station (such as Siemens TIA Portal), making it convenient for users to manage and obtain the configuration and diagnostic information of the switches in the PN master station.
(6). Possess rich diagnostic functions
Based on the characteristics of Ethernet communication (fast speed and large data volume) and the working principle of Layer 2 switches – different ports forward different packets according to their respective Mac address tables, making it difficult to capture comprehensive data in the network through third-party devices. Therefore, it is necessary for switches to have built-in diagnostic functions. The DINGSHI PN switch not only has diagnostic functions for general management switches, such as port status monitoring, mirroring, etc., but also has diagnostics for the PROFINET protocol, such as monitoring and triggering settings for PN-alarm messages.
5.3.3 Configuration functions of PN managed switches

6.4 PROFIBUS-PA protocol module, customized circular card
6.4.1 Product Usage and Customer Orientation
PROFIBUS-PA protocol module PAMODE, customized circular card, provides communication circular card solutions for manufacturers to independently develop PROFIBUS-PA instruments and meters.
6.4.2 Product form
6.4.2.1 PA module DS-PAMODE
User independently developed instrument communication circular card. The PAMOD module can be embedded as a core component in the PCB of user development instruments. There are two types of PAMODs:
PAMOD-A type: only includes the communication part and industry regulations. The sensor measurement data and parameters are transmitted to the module through SPI/UART by the instrument CPU.
PAMOD-B type: includes a complete line gauge and AD circuit section, which can be directly connected to the instrument sensor output (or necessary analog circuits are required).
6.4.2.2 DINGSHI provides customized user instrument communication circular cards based on PA module DS-PAMODE
6.4.3 Application Principles
Using the DINGSHI PA module DS-PAMODE, develop a communication circular card for user products (such as PA pressure gauges), and build a development platform as shown in Figure 6.3-1: Example of PAMOD used for a PA instrument development system. The PA module is powered by the PA bus, and the user’s instrument circular card receives power from the PA module.
The PA module DS-PAMODE is a super functional protocol chip application, and users do not need to worry about PA side development. They only need to transmit the required data of the pressure gauge to the PA module through SPI and UART. DINGSHI provides rich APP application functions, user side development routine source code, detailed hardware schematics, and evaluation board schematics.
The development system includes a PA master station and PA diagnostic software for debugging. It is recommended to use the DINGSHI PROFIBUS-PA diagnostic tool PBStudio2.0, which includes the Master and Master configuration diagnostic software. The functions include: configuration and Master functions, station status, communication message recording, PA waveform monitoring, DTM parameter debugging, and other functions.
6.4.4 Product advantages
(1) Short development cycle
Compared to other industrial control network protocols, PROFIBUS-PA has a complete application layer protocol and product specifications to ensure the interconnection and seamless replacement of third-party products.
If instrument engineers independently develop PROFIBUS-PA communication round cards, on the one hand, they need to be proficient in the protocol technical details of PROFIBUS-PA V0/V1 (C1+C2), and further require compliance with PA regulations (with detailed regulations for various instrument parameters and functional blocks); These requirements go beyond the technical background of general instrument engineers. On the other hand, the instrument requires sufficient standardized parameters to be transmitted to the PROFIBUS-PA network, and currently, the parameters of most “non PA instruments” are far below the requirements of PA regulations.
By using the DS-PAMODE protocol module and customizing the circular card, firstly, development engineers do not need to understand the technical details of PA V0/V1 (C1+C2) protocol, nor do they need to know the details of PA regulations. They only need to transmit the instrument parameters to the module/customized circular card through UART/SPI. For some unnecessary PA regulatory parameters that are missing from user instruments, modules/customized circular cards can be simulated and provided to the PROFIBUA-PA master station to complete communication connections.
Users can complete PA communication round card instrument debugging within a week by providing evaluation versions, user source code, APP functions, and online technical support through DINGSHI.
(2) Complies with PA international technical standards
