SCADA is a system that mainly visualizes processes and logic embedded in PLC drivers. Its tasks are gathering information, alarming and providing graphic representation of the processes taking place. As opposed to SCADA, apart from the functions that it has, Nazca includes logic and actually has the ability to control processes. It also provides more advanced features of visualization, alarm, reporting, remote access (also from a mobile client), building advanced algorithms and most importantly, integration with other systems, both hardware and software.
Similarly to the programming of industrial controllers, logic is based on transmitting signals between the outputs and the inputs of blocks representing physical devices or logical functions.
Licensing is based on two elements:
- The first one is the Core which is licensed due to the number of nodes and variables in the system;
- the second one is individual functions and protocols which are not limited in quantity and chargeable once regardless of the complexity of their use in the system (e.g. Modbus, OPC, camera window, etc.);
The entire licensing and calculation of system components is based on an Excel calculator. A special license is used for operator stations. They are licensed according to the number of computers connected to the system. The license key is encapsulated in an APA supplied HASP key or time-limited software license.
Among others, in Rosevia Restort (a hotel apartment complex - Jastrzębia Góra), Smolna 40 (Indigo Hotel - Warsaw), Plaza (shopping centre - Toruń), HTM (Research and Development Centre - Gliwice), Tesko Steel (steel logistics centre - Rybnik), APA (Black House - Gliwice), Woodward (electronic components factory - Niepołomice), Grójecka (office building - Warsaw)
YES, WE DO.
OpenData - a simple and clear way to share data with other systems through open communication protocols, REST or AMQP message broker. BigData - a very complex issue related to gathering, analysis and visualization of large data sets (and more importantly the choice of those important ones from the BMS operator's point of view). The most convenient way is to perform analysis in the Cloud (e.g. Microsoft Azure) with which Nazca is integrated.
The service is provided by the APA Partner which implemented the system. Normally, a 5-year warranty is provided for APA devices and software. Individually, a longer warranty may be considered - up to 10 years with additional payment.
YES. There is a service hotline: +48 530 412 554 (7 days per week: 6:00 a.m. - 10:00 p.m.)
YES. Nazca can work on many servers that are connected to a larger system, then each of them is responsible for a small part of the whole.
Data are stored in two databases (SQL - for configuration, Mongo - for data from measuring systems and sensors). The databases, as well as the whole system, are password protected. The communication between the client and the system is encrypted. The client is responsible for adequate protection of the network in which Nazca operates against unauthorized access. Additionally, we have an integrated system of sound authentication by means of ELIoT Pro system.
Communication with the system can take place via local network, Internet connection (ideally with public IP address) – this applies to operator stations. Through the Internet with the mobile client and by means of text message and e-mail. External communication is protected by the MQP TLS protocol.
The following protocols can be used to enable communication between the system and facility devices:
- Modbus TCP (ETH)
- Modbus RTU (RS-485)
- BACnet IP (ETH)
- Vibus (RS-485)
- OPC UA
- OPC DA Other protocols (DALI, LORA, KNX, M-Bus, LON, Profibus, etc.) are supported by dedicated communication gateways of external manufacturers.
There are four different ways in which graphics in Nazca can be created:
1) the simplest one is to build buttons, warning devices, charts, etc. from already manufactured Nazca elements
2) creating graphic schemes (e.g. of ventilation and/or heat/cooling units) using the animated widgets integrated into Nazca (drag & drop)
3) creating raster graphics - a bitmap (by a graphic designer) and applying zones that can be highlighted, framed, etc. for creating spatial visualizations
4) using WEB plug-in for creating graphics based on html and related environments (e.g. Grafana).
Work on implementation of vector graphics and BIM files is in progress.
YES. We offer a dedicated application for mobile devices (smartphone, tablet) for Android and iOS, both for Nazca and Vision. The mobile client is chargeable depending on the number of users.
YES. The system is reliable. If the client requires additional Reliability Guarantee, it is possible to create a redundancy system (of course, the limitation then are the buses and devices connected to the system and their control capabilities from two or more levels) - to achieve this, it is necessary to set up at least two computers and mirror the configuration, as well as to back up the databases on an ongoing basis.
Another issue is to ensure reliability by creating a distributed system, but then it is necessary to build the system using programmable devices (PLC) in which Nazca takes over the role of the PLC management system.
YES. Each system is built for a specific investment and programmed according to the client's guidelines. The modules consist of individual software elements. As far as scalability is concerned, there are basically no limitations in this respect.
We have a possibility of providing video transmission - streaming of images from IP cameras via RTSP protocol. Then we take one video stream from the camera to Nazca and the second one goes to the video recorder (if there is one in the building).
Nazca does not provide functions such as: recording, storing, and searching the recordings from CCTV monitoring.
YES. Nazca has a built-in event log. It can record any events related to system operation (e.g. alarms, changes in parameters, opening of passages, etc.). Additionally, the system logs user operations (who? what? when?). Each entry in the event log is time stamped and there is a possibility to give appropriate priority to a particular group of events.
Nazca has the potential to increase energy efficiency of the buildings in which it is applied by skillfully and cleverly controlling building installations and reducing the waste of energy on contradictory actions (e.g. open windows along with working air conditioning). Continuous analysis of energy consumption, prediction of peaks (increased power consumption) and control of devices can act as a power guard. The guard can both alarm the user when power consumption is exceeded (or when there is a possibility of its exeedance - through cloud analysis), but also automatically control the low-level programs in such a way that exceeded power consumption is not possible without operator’s interference.
Nazca has the ability to detect anomalies both in the operation of building systems and self-testing (Nazca Monitor) - thanks to this, it can diagnose itself and inform the user about the problems.
YES. The price is determined using a simple Excel calculator.
Update is possible, but not necessary. It is usually chargeable because it may also involve additional programming work. The purchased version is lifelong. An update can be made for free as a business courtesy. Each time it must be considered individually and done in a controlled manner.
Additions to the Nazca system can be found in APA's portfolio. This may be SRS, Access Control, Tweanser, i-Poe, etc. But it can also be a functionality in the form of a simple CodedNode (freely definable node). A partner has the right to freely choose external solutions cooperating with Nazca.
Profits can occur on many levels. It is worth remembering that usually the construction of a facility is less than 20% of the total expenses related to the subsequent maintenance of the facility (e.g. for 15 years). If Nazca is able to save at least 3% of the operating costs (and more than 40% are the costs of energy alone) then:
- converting 3% into 80%, this comes to 2.4% of the investment
- taking into account the construction cost - almost 10% of the construction cost
For example, if the investment costs PLN 30 million (in total) and the Nazca system – PLN 500k, then assuming the said 3%, Nazca will save about PLN 2.5 million. In addition, you have to count the staff costs (reduced operation and ease of use, intuitive interface - and thus ease of training). It is also important to remember that profits do not have to translate directly to money, and the profit can also be increased comfort and prestige of the investment.
Thanks to Nazca, the location and the building itself may be more attractive for potential tenants.
It is possible to create a system in any language – it is a matter of descriptions and programming in that language. Currently work on localization in English, German and Dutch is in progress.
There is no need to have a local operator. The operator can manage the system remotely, e.g. one operator for several buildings.
YES. The system can be implemented for a trial, however, it should be remembered that it involves both infrastructure and programming. We can e.g. demo the solution or offer the SRS system (without panels) for testing. In the demo version a time-limited key is generated.
For all objects, and moreover, it does not have to be a building. These can be vehicles (trains, trams, yachts), industrial solutions (robots, production lines), dispersed structures (street lighting, trash cans, etc.). Basically, there is nothing that limits us in this respect - it is important that there are systems for integration and/or control or metering.
Data from Nazca can be exported e.g. to the cloud and to the other computers. Nazca itself can export to *.csv and *.pdf files and send e.g. e-mails or text messages with reports.
The system as such is for life. Once in operation it will work for many years - only gradual maintenance and possible replacement of the hardware components are necessary. The software itself does not need to be supported even if something happens. However, given the sales model and the network of partners that APA is building, both support and people who know Nazca will be on the market for many years. The APA itself is not a new creation, we have been on the market for more than 17 years and there are no plans to change that, so the client can be sure of support from both the manufacturer and the implementation partners.
The size and type of object and the number of tiers. Additionally, information about the number of elements included in the composition, range of functionality, what we will control, what we will monitor, etc. What other systems are foreseen in the facility – intrusion and hold-up alarm system, fire suppression system, CCTV, access control, etc.
There are also issues related to service, but this is the responsibility of the partners.
