Brief Introduction to the Industrial Ether Network
The nature of the Industrial Ether Network is also the Ether Network, which the original intention is to add some elements to the industrial application demand on the foundation constructed on the Ether Network, or improve part of the software and hardware functions for further and proper use in the industrial applications. The following is introduction tosome special specifications in the industry-level Ether Network.
Power Input
Power is the link with first priority. Generally, there is convenient power supply in the mechanic room end, so people do not have to worry about the power supply issue. However, under considerations on back-up and stability, double or multiple power input or UPS system are necessary, which can be classified into two parts in respect with application-- one is HV (High Voltage), and the other is LV (Low Voltage). For HV, it is generally AC 110/230V; as to LV, it is generally DC 9~60V or DC 24V frequently used by PLC/IO. As far as the convenience of acquiring power, AC power is a solution project with more convenience. If the equipment is DC, it has the advantages such as stable signals, and convenient operation of online maintenance (DC with input less than 48V is safe voltage). If there is only AC power on site, AC to DC power switch can be applied to supply power. Additionally, the special DC 100V is the specification often seen in some power applications, as listed below:

According to customer's demand, the industrial Ether Network's equipments in respect with power supply part are characterized with easy installation and maintenance, backup design, and High MTBF.
- Modularized power design, dual DC, dual AC, or mixed dual AC or DC to be used in different environments and applications.
- Hot plug design without the need to halt the equipment's operation for replacing the power module.
- Synchronic input of dual power to ensure the operation of equipment will not be interrupted or rebooted.
- Wider input range can avoid abnormal equipment operation or reboot caused by unstable power supply.
- Separation of the power set and main equipment body or plug-in can raise the MTBF.
- Insulation from Serge can avoid surges that may damage the equipment
- Use of lightening arrester can alleviate the system damaged by thunder attacks, particularly in the outdoor applications.
Indoor Application Take factory automation as example, the Industrial Ether Network covers extremely extensive range of application, from in-plant main system (line of production) to plentiful subsystems (water, air, chemicals, and electricity). Basically, the industrial Ether Network is primarily exerted in the in-plant backbone system or for system monitoring. In addition, it can also be applied to connecting the network in the office and logistic system. The common applications and power supplies are exemplified in the following Table:

According to different applications, anti-water and anti-dust have different demands in indoor application. In some production lines with high humidity and dust amount like paper factory, printing factory, steel factory, etc., anti-water and anti-dust is necessary. On the other side, in some high technology factories, most mechanic rooms own air conditioning and anti-dust treatment, so it is not necessary. Besides, through some cabinets with high tolerance, anti-water and anti-dust effect can be achieved as well. Generally, the anti-water and anti-dust performance can be defined by IP level, as listed in the Table below:
|
IP-XY |
|
|
|
|
X = |
0: No protection |
Y = |

In respect to customer's demand, regarding the industrial Ether Network equipment's anti-water and anti-dust, the application orientation, easy maintenance, cost reduction are the primary concerns.
- IP20 is the basic demand. Higher level of anti-dust will not be beneficial for the equipment's heat radiation performance.
- For mechanic room without any air-conditioning or people, IP30 or higher is recommended. The dust in the environment may cause equipment's short circuit as well.
- In humid indoor environment, IP65 or above is recommended, which can be applied in collaboration with the anti-humidity cabinets.
- IP67 or above is recommended for marine or ship operation, for the anti-water efficacy is enough in this case.
- For environment with acid or alkaline gas in air, such as seaside, chemical factory, etc., PCB Conformal Coating is recommended to effectively prevent the electric products to be corroded and destroyed.
Indoor ApplicationTake paper making factory for example, the industrial Ether Network is utilized in connection between the equipments, electricity and water treatment monitoring of the equipments, or embedded inside of the machine. Although it is located inside the indoor environment, the temperature and humidity are relatively higher, and have greater impact on the electronic products as well, so the requirement on anti-water and anti-dust must be stricter correspondingly. The applications and the needed protection level are exemplified as follows:

Temperatureis a big concern for electronic products, because the products tend to crash and the efficiency may decline in high temperature, while in the low-temperature environment, it may encounter difficulty in booting the host. This is why heat radiation design plays a particularly important role for the industrial equipment. Applications in the mechanic rooms with air conditioner do not demand a lot on the temperature. Generally, room temperature with +/- 100。C is the frequently seen specification, so the common electronic products all support around 40~45∘C. Regarding industrial applications, the range will be slightly adjusted in correspondence to different applications. In addition, temperature in different regions has different basic demand on the basic requirement. What follows is the temperature demand on some areas and applications.

In respect of customer's demand, temperature of the industrial Ether Network equipment in the application in the mechanic room plays a crucial role. In addition, it is applicability oriented, and the area, climate, and environment are influential factors as well.
- In temperate zone, sub-zero temperature is not common, so it will be enough to set the low temperature around -10℃. As to high temperature in summer, 55℃~60℃is enough to meet the demand.
- In the Tropics, sub-zero temperature will not occur, for it is generally warm or hot, so for considerations on outdoor application and sunburn, it will be okay to set the low temperature at 0℃ and the high temperature around 70℃~75℃.
- In frigid zone, the high temperature does not exceed 40℃ mostly, so it requires more attention for extraordinary low temperature. In Northern Europe or Northern America, -20~-30℃is quite common for the local inhabitants.
- In special zones like desert and Middle East, the temperature in the daytime and nighttime differs considerably, where the temperature can swing between -10℃and 55℃. In areas like Siberia, extremely low temperature around -50℃~-70℃ can even occur, which is a big challenge for both the industrial equipmentand the vendors.
Indoor ApplicationTake steel factory as example, the indoor environment is hot and humid, so it needs to consider more on use of equipment. Generally, there are air conditioning in the control room or mechanic room, and it is recommended that the factory equipment can support to around 60℃in more isolated environment. As to some working areas with relatively higher temperature, such as converter, blast furnace, and so on, it will better if the industrial equipment can support temperature up to 75℃.

Outdoor ApplicationTake oil well monitoring as example. Generally, oil well's information is transmitted to the central control terminal via optical fiber system. However, in each oil well zone, the working environment is often considerably poor. It is often situated in the polar zone or desert. In polar zone, the temperature is low enough to freeze the pipes, while in the desert, the temperature difference between day and night or sunny and rainy days reaches more than 60 degrees, which is a big challenge for heat radiation and tolerance design. Therefore it is very important for the main systems, like injection system, power supply system, oil well monitoring, emergent shutdown system, and so on. The frequently seen applications are listed below:

Special Certification For industrial application, it is a kind of quality guarantee and promise that each vendor commits to the industry. Generally, it involves with certification aiming at personnel safety, certification aiming at anti-fire and anti-explosion, maritime affairs certification used in maritime application, vibration certification aiming at transportation application, and so on. Basically, as far as the electronic products are concerned, CE, FCC are necessary certifications, representing that the products have basic reliability and quality warranty. To step further, safety certifications like UL60950, UL508, and so on will provide protection in a higher level for customer to use the products. The common demands on certification are listed in the following Table:

In respect of the customer's demand, regarding special certifications involving the industrial Ether Network, it relates to applicability orientation, obedience to laws and industrial regulations, for more certifications there are, the more protection will have. The industrial Ether Network equipment vendors should take the following considerations as priority.
1. For special market and the vertical industries, research must be conducted while introducing the corresponding certifications, such as vibration regulations for transportation application and anti-explosion certification in petroleum application.
2. For optimization of the specification of the product's software and hardware to meet the demand of special applications, such as avoiding sparks, anti-salt and anti-corrosion, anti-electromagnetic.
3. Understand the market trend and regulations in different countries in the future to help promote the industrial Ether network applications.
Indoor ApplicationTake petroleum factory for example, sparks are enough to lead to great loss of life and property. Therefore, fire is forbidden in the factory. Regarding electronic equipment, low power consumption, fan-less designs are adopted extensively. In addition, attention must be paid to the movable articles that may gender sparks. The industrial Ether Network equipment in the petroleum factory is required to pass the anti-explosion certifications with different levels, including the European ATEX Zone 2, the U.S. Class 1 div 2, and so on. In even more dangerous regions, all-dimensional protection or Class 1 div 1 and ATEX Zone 1 are all necessary. Some applications are exemplified in the following table.

EMI/EMS Requirement for Industrial Ethernet Solution
IEC 61000-4-5: Surge Immunity Test
IEC 61000-4-5:2005 relates to the immunity requirements, test methods, and range of recommended test levels for equipment to unidirectional surges caused by overvoltage’s from switching and lightning transients. Several test levels are defined which relate to different environment and installation conditions. These requirements are developed for and are applicable to electrical and electronic equipment. The object of this standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to surges. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. This standard defines: ISON Technology tested our product by high level surge immunity test, even up to 2KV on the RJ45 ports, in order to prevent unexpected surge at the harsh environment.
Hipot Test
Hipot Test is short name of high potential (high voltage) Test and it is also known as Dielectric Withstand Test. A hipot test checks for “good isolation.” Hipot test makes surety of no current will flow from one point to another point. Hipot test is the opposite of a continuity test. Continuity Test checks surety of current flows easily from one point to another point while Hipot Test checks surety of current would not flow from one point to another point (and turn up the voltage really high just to make sure no current will flow). Importance of HIPOT Testing. The hipot test is a nondestructive test that determines the adequacy of electrical insulation for the normally occurring over voltage transient. This is a high-voltage test that is applied to all devices for a specific time in order to ensure that the insulation is not marginal. ISON Technology done the Hipot test by high standard, even up to 1.5KV between ports.
