The SO-55 device is a modular communication and control controller, included in the SO-5 station devices. The concept of construction of the SO-55 concentrator is based on the idea of reading data from external devices using a protocol appropriate for a given device, standardizing them, placing them in the database and then making these data available to other devices communicating with the concentrator, or virtual devices that are software modules in the concentrator .
The SO-55 can work as:
As a protection concentrator, it supports the majority of protections operating at power stations. The ability to change the number of modules and reconfigure the concentrator allows you to add communication channels with new devices.
Basic prices of the SO-55 controller as a security concentrator:
The SO-55B-KSP controller is designed to monitor and control devices included in the DCM-100 system (input/output modules) and other dedicated building automation devices. The SO-55B-KSP controller enables the implementation of distributed telemechanics and supervision of actuators. Thanks to the use of standardized communication protocols, the controller can be used to cooperate with superior systems of other manufacturers. It was built on the basis of modules intended for the implementation of applications used in difficult environmental conditions such as electromagnetic interference, humidity.
The controller consists of a set of modules placed in a 4”/6U housing. The modules are connected and powered by an internal communication bus.
The controller consists of the following modules:
The SO-55B-KSP data concentrator is the hardware platform of the ARGUS-RV system and has been tested by the CNBOP-PIB certification body. Certificate of conformity No. 3328/2018 (attached below) was issued, confirming compliance with the technical specification and the possibility of using it in the construction industry in the field of monitoring and control of technical protection systems and facility security management. The certificate is also available on the website of Telbud SA (//telbud.pl/en/About us/Licensese and certificates/). 
The SO-5S-KZ protection concentrator provides remote access to digital protections and other devices installed in the station. Appropriate software for communication with all devices (SMS Base, DIGSI, Cap501, etc.) is installed in the security concentrator. The connection with protections or other IED devices (Intelligent Electronic Device) is carried out via an Ethernet link or serial ports, which are connected by means of STC-140 transmission multiplexers to a specific device.
Another element of the SO-5S-KZ is the SynGraf-KZ program, which allows for quick access to the required device by setting the transmission path and launching the appropriate proprietary program.
The STC-140 multiplexer network is supervised by the Connection Manager installed on the SO-5S-KZ. In addition, it periodically tests connections with all devices connected to the concentrator. The status of connections is visible in the SynGraf-KZ program and is also sent to station concentrators, from which it goes to the local SCADA class system. 
The real-time server of the SYNDIS SO-5S system is designed to support data acquisition functions, storing them in the database and processing them according to the implemented algorithms. The server also performs all functions related to data sharing, conversion and support for multiple transmission protocols.
Depending on the application, the appropriate software is installed on the server:
A protection concentrator can be an independent device such as SO-5S-KZ or a virtual one installed on hardware that performs several functionalities. It is then possible to run multiple virtual concentrators on one physical server. An example structure is shown in the diagram below.
