Selection Manual
All gateways of the EG series are highly consistent in their usage. The difference between different models is mainly reflected in the hardware interface, and the corresponding difference is only the presence or absence of certain nodes. Therefore, this series of documents applies to all models of the EG series, unless otherwise stated.
Featured Functions
The EG Edge Computing Gateway series has several models, whose software functions are kept synchronously updated. The difference is mainly reflected in the processor performance, hardware interface, product form and so on. The introduction of the featured functions takes the EG8200Mini-SLIM version as an example:
1. Product Positioning: Focus on Data Acquisition and Protocol Conversion
2. Rich PLC Protocol Adaptation
Supports the private protocols of mainstream PLC brands (Note: This is not a simple Modbus protocol; many manufacturers change the concept that their products support a variety of PLCs. The actual requirement is that the PLC supports Modbus), a large amount of memory, and unlimited data points.
3. Multiple industry protocols
4. Remote O&M, Remote Programming
The demo account we provide is a real gateway running in our company with remote O&M enabled. With this feature on, the gateway is just like being at your side, without any wiring, you can access the configuration page and programming page of the gateway anytime and anywhere. The design of this function greatly reduces the operation and maintenance cost of the gateway, you can do this:
① After installing the gateway on site, you only need to ensure that the networking is normal, and the configuration and programming work can be realized remotely
② The demand keeps changing, and you don’t need to travel to the site, and you can modify it remotely
③ The data at the site is abnormal, and you don’t know what the reason is, and you can debug it remotely
④ ……
5. Virtual Network Port, Virtual Serial Port
Virtual Network Port allows your computer to remotely access the LAN where the gateway is located, and is used for debugging operation and maintenance of network devices in the same LAN.
Virtual Serial Port allows your computer to remotely access the devices connected to the serial port of the gateway, and is used for debugging operation and maintenance of serial devices connected to the serial port of the gateway.
The design of this function, you can do this:
① Remote uploading and downloading PLC program
② Remote Upload and download PLC program remotely ② Upload and download touch screen program remotely (except USB)
③ Remote O&M server (SSH, Openwrt, router, etc.)
④ Remote debugging of serial sensors
⑤ ……
6. Data storage
Supports a variety of data storage methods:
Cache Queue: disconnected data can be cached in the queue, FIFO first-in-first-out, the maximum storage space is 90% of the upper limit of the memory, the disadvantage of power-down disappeared
File Read and Write: the data according to the needs of the data can be written to the file stored in the memory card, suitable for small amounts of data, low-frequency data storage, the disadvantage is the efficiency of the low
InfluxDB: data according to the needs of the data written to the Timing database, you can write sql statements according to your own needs to achieve the desired function, no drawbacks
7. Network self-recovery
The lifeblood of the gateway is network stability. The EG8200Mini-Rail version supports multiple network communication methods and automatic switching.
8. Visual Programming
The biggest advantage of the EG series is the visual programming, please refer to Quick Start for more details.
9. Low customization costs
The EG series benefits from visual programming and a large number of self-developed nodes. Both interfacing with sensor protocols and interfacing with third-party platform protocols (MQTT protocol, Json format customization) are very fast. As a result, the cost is significantly reduced. The gateway does not come with any features from the factory, but only provides the basic capabilities. You can develop your own gateway according to your own needs. Will not? Feel free to harass customer service.
Basic Concepts Need to Known
This article focuses on the basic concepts you need to understand when using the EG Series Edge Computing Gateway.
1. Hardware Interface
| Concept | Descriptive |
| 4G Full Netcom | Support China Mobile, China Unicom and China Telecom SIM card 4G communication |
| 5G Full Netcom | Supports 5G communication with SIM cards from China Mobile, China Unicom, and China Telecom |
| APN Private Network Card | The SIM card provided by our company has no limitation and can be directly connected to the Internet. But a large proportion of IOT cards have networking restrictions, generally divided into two kinds: one is to provide APN information (APN access point/username/password) dial-up networking; one is to set the IP to be communicated as a whitelisting that is, the directional cards |
| Machine-Card Binding | IoT card currently have this limitation, a card inserted into the gateway and networking is automatically bound, the card can only be used in this device, change the device that locks the card, you need to look for the opening party to unlock the card to be able to use |
| WAN port | WAN, which can be simply understood as the interface of the gateway to the outside network |
| LAN port | Local Area Network (LAN), which can be simply understood as the interface of the gateway to other devices that feed the network |
