For more than 15 years INDUSTRONIC has offered training courses to their customers and partners from around the world. Over the years, the need for training and the requirements have grown constantly. Due to the change from analog to digital technology the systems have become more and more complex. At the same time, we have developed new products leading to an extension of our product portfolio. This makes training courses even more important.
Now, we hold around 45 different training courses for customers, system integrators, or partners every year. The major part of them takes place in our headquarters in Wertheim in our modern and well-equipped training rooms. But we are also flexible and can offer training worldwide, directly on site.

Industrial communication and public address systems provide various functions. They propagate life-saving information in dangerous situations, ensure fast and process-related communication and provide various interfaces (see Intercom and PA/GA).
Communication procedures can be assigned with different priority levels so that the operators maintain control over the situation. This is the case, when several events occur at the same time, e.g. a voice connection needs to be established and an alarm triggered. Based on the priority, the system decides which function is executed. Read more »
The ingress protection ratings (short form: IP ratings or also called IP codes) classify the degree of protection that an electrical appliance provides against the ingress of solid objects, dust, accidental contact, and water. The different IP ratings are included in the IEC 60529 standard developed through the International Electrotechnical Commission (IEC).
An IP rating consists of two digits followed by optional letters to provide additional information related to the protection of the device. The first digit stands for the protection against solid objects (including body parts such as hands or fingers) and the second one for the protection against water. Find an overview chart describing the two digits by clicking the screenshot on the right.
There also exists a second standard, the NEMA 250. IP ratings are primarily used in Europe, whereas the NEMA ratings are used in the USA. IP and NEMA ratings are not identical, but similar and can be compared. IP ratings only consider the protection against the ingress of solid objects and water, whereas NEMA ratings also consider other characteristics such as corrosion protection, construction details, and environmental requirements.
Find an IP ratings chart and a NEMA ratings chart with IP rating equivalents in the PDF to compare these two ratings. This PDF can also be downloaded from our Info Center. For more in depth information on the NEMA 250 standard, please visit the following website http://www.nema.org/. Also visit the website of the IEC to find more details about the IEC 60529 standard: http://www.iec.ch/.
INDUSTRONIC uses the European IP ratings for its products. The digital explosion-proof (hazardous area) intercom stations of the DX/DXE 0×5 series are rated IP66, for example. The first digit means that the intercom station is dust tight. There is no ingress of dust and it is completely protected against contact. The second digit indicates that powerful water jets against the housing don’t have a harmful effect.
Applications & Product Management: a post by our colleague Thomas Merz
During the last few years more and more customers have asked for maritime offshore certificates, especially the DNV Type Approval.
Therefore we started in late 2012 by assessing the DNV approval requirements for offshore PA/GA systems.
First, we decided on the components of the INTRON-D plus system which were important for us to pass the certification process. The final system for approval was designed as a high level secured A+B System in shared operation. Our intention behind this was to build a system with as many components as possible from our construction kit in order to ensure that the options most required by our customers were covered. We selected our outdoor, explosion-proof, as well as our indoor intercom stations and the IP based Access Panel for the certification process as each of them has the option for redundant system interconnection.
In early 2013, we started with the laboratory tests to evaluate electromagnetic compatibility (EMC), vibration and various environmental conditions. After making minor adjustments to the system, we passed all tests meeting the international standards required (e.g. SOLAS, DNV standard for certification 2.4, IMO A.1021(26), LSA Code, etc.) and forwarded the reports to DNV Norway for approval.
Finally, an examiner of DNV Norway visited us in Wertheim to verify that our INTRON-D plus system complies with the DNV rules and guidelines. During his visit, all functions required for a PA/GA system were successfully tested, e.g.:
• General Alarm mutes entertainment system
• General Alarm activates ship whistle
• PA emergency announcement mutes an external General Alarm temporarily
Fulfilling all criteria required during this performance test was the final step toward approval.
In October 2013, we received our DNV Type Approval Certificate for the INTRON-D plus system. This proves our commitment to ensuring that our high quality standards are met in the offshore market.
We would like to thank our customers and partners for their positive feedback and increasing support for our Christmas Charity Campaign “Donations Instead of Gifts”.
Our customers and partners from around the world cast their online votes for one of four charity organizations which were selected by INDUSTRONIC. The donation in the amount of € 6,000 will be distributed according to the votes cast.
Once more, the “SOS Children’s Villages“ received most of the votes. The local project DLRG Wertheim (German Life Saving Association) came in second. This non-profit organization will add our donation to their savings for buying a new rescue vehicle.
Next came the “Worldwide Initiative for Social Commitment” followed by the DAHW – German Leprosy and TB Relief Association.
We are happy to support the valuable work of these charity organizations!
4712 – The Year of the Horse
Reflections on a Chinese Tradition: The Chinese New Year, also known as the Spring Festival, is determined by the lunar calendar and changes each year with the moon cycle. It varies from late January to early February. The ancient Chinese calendar dates back nearly 4000 years to the Shang Dynasty. Each of the months in the twelve year cycle is depicted by a different animal or creature. It is said the people born in each animal’s year have attributes relating to the respective animal. The spirit of the Horse is recognized as energetic, bright, warm-hearted, intelligent and able.
The preparations for this festival start in the few days of the last quarter moon: doors are decorated with red paper scrolls, red rice lanterns are hung in homes and incense is burned. It is a time of family reunion and large family dinners are served. The color red is thought to symbolize fire and ward off bad luck and the evil spirit Nian. Also, most Chinese people set off fireworks at midnight to scare Nian away. Red paper envelopes are filled with money, decorated with luck symbols and given as a gift – they are known as “Lai Si” or “Hung Bao” and represent a wish for wealth in the New Year.
In this spirit we would like to wish all of our colleagues, customers and friends a Happy Chinese New Year!
Already in 1977 INDUSTRONIC supplied their first systems to China through international engineering companies and contractors. Due to the good business relationships and the booming market INDUSTRONIC decided to found a Representative Office with 2 employees in Beijing in 1999. At the beginning, INDUSTRONIC focused mainly on customers in the Chinese metal industry.
The growing success also in other industries such as Oil & Gas, Chemicals & Pharmaceuticals encouraged INDUSTRONIC to transform its Representative Office into a Wholly Foreign Owned Enterprise in July 2002. Ever since, INDUSTRONIC Beijing, as subsidiary of INDUSTRONIC Wertheim, has grown steadily and has become a recognized provider of industrial communication systems for the Chinese market.
Under the management of Ms. Wu Mingfang the employees of INDUSTRONIC Beijing are responsible for different projects across various industries. Here are some references of their customers in China:
Metals, Minerals & Mining: Anshan Iron and Steel Group, Shougang Group, Baoutou Steel, Magang, Baogang Group
Oil & Gas / Chemicals & Petrochemicals: CNOOC, SINOPEC, PetroChina, China National BlueStar Group, BASF, Bayer
Energy & Utilities: Weiqiao Power Plant, China Guodian Corporation, China Huadian Corporation

“No matter how important the project is – INDUSTRONIC’s primary objective is to prevent accidents and to safeguard the health and safety of every employee.” This sentence describes the principle of our HSE manual (health, safety and environment manual). We have defined priorities for safety and health at work as well as for environmental protection in all operating areas of our company. In order to show you our commitment, INDUSTRONIC’s HSE management system was certified according to the SCC standard.
Additionally, many of our European customers also demand a proof that service employees working in their plants have been instructed on safety. With the SCC certificate we fulfill the wishes and needs of our customers and are allowed to work at locations where the SCC certificate is mandatory.
You may ask yourself what is the purpose of a SCC certificate (SCC = Safety Certificate Contractors) and what are the benefits?
The SCC certificate was developed to assess the quality of contractors in terms of safety, health and environmental protection. Contractors are companies which provide technical support and other services for its principal based on a service contract. INDUSTRONIC often takes on the role of the contractor itself, as its service employees perform maintenance work on existing production plants and also play an active part during the installation of a new system or the expansion of an existing one.
Booking a flight or a hotel, buying a DVD, checking your stock market price, watching a video – nearly everybody uses Internet, Mail, SMS or other services which are based on IP technology. Even if you make a call with your home phone you use IP technology, because most telecom providers employ IP exchange technology in their backbones.
These days, we are surrounded by IP technology everywhere we look – almost nothing in our technical world would work without it.
IP – What’s it all about?
IP is short for Internet Protocol and is part of a so-called protocol stack. This ‘stack’ – Transmission Control Protocol / Internet Protocol (TCP/IP) – is responsible for transport, interpreting and processing of data on physical media, for example.
Different layers are stacked to handle and interface between hardware, protocols, transport and applications.
Industrial Communication – Now and then…
Until now, traditional industrial communication has been managed e.g. with dedicated cables in star topology. Each end device is connected directly to the central exchange.
Field devices can be 2 miles or more apart using just one twisted pair cable – data, audio and power included. All connections are exclusive, guaranteed and immediately established.
In other words: You have your own ‘cable network’, your own devices – everything is under your control and simple.
…now and in future
IP technology took its place in industrial communication about 10 years ago. First slowly, but its popularity has increased rapidly in recent years. The technology is mostly reliable and usable in many applications.
If all these necessary parameters for optimal output are provided at customer side, the network performance is as good as the old-fashioned dedicated star wired cabling.
Keep in mind that CAT cables and PoE can only cover distances of 100 meters (328 ft.). That means your infrastructure, like switches, power supplies, etc. must be much more decentralized and well distributed.
Network infrastructures must be protected against failures or a single point of failure with redundant structures or other actions.
With a VLAN you establish a secure connection within an IP network. You are able to guarantee bandwidth, jitter and other parameters, but there is also a risk to get this VLAN corrupted by DDOS attacks or disturbed by other impacts.
What can we learn from this?
IP technology is already an integral part in our real world and in fact a good solution in many situations and applications. This is also true for IP industrial communication if all constraints are observed.
If everything counts, then a ‘State-of-the-art Industrial Communication System’ will combine the best of both worlds:
- IP technology for modern end devices
- IP technology for latest protocols, like Modbus TCP or SIP
- IP technology for wide data paths connecting central systems
- ‘Old-fashioned’ digital technology for long range connections
- ‘Old-fashioned’ digital or analog technology for connecting existing equipment
So only a hybrid system can satisfy user demands in all applications and under very diverse industrial conditions – especially if you take into account the costs for a reliable system.
Greeting from the President 2014
Our lives are becoming increasingly complex, fast paced and globalized. This is also true for our market.
The complete project chain up to the end user often comprises four or five processes – starting with FEED (Front-End Engineering Design) through to EPC contractors (Engineering, Procurement & Construction), system integrators, the customer in the plant or the company placing the order and finally the end user who is the last one in the chain.
Each of these parties has its own ideas regarding the system design and communication functions. The deviation of these ideas is often much larger than the parties actually expect. Sometimes detail knowledge of on-site requirement is missing, too.
INDUSTRONIC therefore offers consulting and technical advice as a separate service for its customers. Depending on the extent of the service – we provide the option to offset these service costs with the price of the system ordered.
Consulting benefits all parties:
• Gather knowledge and gain insights
• Improve collaboration between the parties within the project chain
• Meet delivery times
• Reduce misinterpretations
• Save time, money and resources.
Global Dialog, the new blog from INDUSTRONIC, will introduce you to an array of topics. Among others, these include:
• The diversity of our communication functions
• Modern technologies with reference to the high safety requirements of the market
• Industry topics
• Insights into INDUSTRONIC.
We look forward to engage in a global dialog with you and are interested in your feedback and comments.
