The family of modular devices SO-52v12 has been designed to implement various functions of automation and telemechanics systems in power transmission and distribution stations. These devices can also be used in industrial control systems for the automation of heating plants, pumping stations, sewage treatment plants and other industrial facilities. Devices made on the basis of modules from this family cooperate with SCADA systems in various transmission protocols.
The block diagram of the controller is shown below.
Each controller of the SO-52v12 family requires configuration using the specialized pConfig software.
The configuration of the device relates to functional characteristics. It includes function properties that result from the intended use and functionality of the device, such as the implementation of synchronization functions, auto-reclosing, interlocks, registration parameters, protection operation, etc.
The configuration software is also used to parameterize individual controller modules, e.g.
This software enables or disables specific communication functions of the device, such as modem support, serial transmission parameters, network transmission properties and types and structures of communication protocols.
Extending the functionality and resources of the driver are possible even after starting the application. This is accomplished by adding additional modules to the controller rack if redundant locations are available.

Modular communication and control device, part of the SO-5 station equipment system. Individual modules managed by a unit. The central PJC perform various types of conversions and connections between the interfaces of devices constituting the station's equipment and master systems or devices.
The SO-55 controller mainly has communication functions, but it is possible to expand it using the SO-52v11 modules, which gives additional functionalities, depending on the customer's requirements.
The SO-55 controller can be used as: a communication controller, a security concentrator, a communication controller with a block of object inputs/outputs, a protocol converter, it can also have the functions of an Ethernet switch, PSTN modem link, support communication in GPRS, trunking and in the 430÷450 band MHz.
Information about the functionality is important at the stage of building the application, because a cassette with a proper division of buses should be provided. The SO-55 controller modules are supported by the MS bus, while the SO-52v11 use the LVDS bus. The use of an appropriate cassette enables cooperation of both buses and mutual exchange of modules of both standards.
The device, depending on the application, can perform additional functions. More information can be found in the group Offer > Products > Devices > Data transmission systems.
The SO-55 controller is built on the basis of replaceable hardware modules, which are divided into the following groups:
The central unit supports communication modules via the MS bus (and the interrupt system). LVDS bus I/O modules are supported by a dedicated high speed serial channel.
The analysis of the application at the design stage allows you to determine the number and types of required communication channels and to select the appropriate transmission modules. A typical application consists of several single and redundant channels, ensuring communication with local or remote control and supervision centers, as well as several to several dozen channels for substation devices and systems. The controller can simultaneously handle different standards and types of transmission. There are galvanically separated RS-232, RS-485 links, current loops, Ethernet links, single- and multi-mode fiber optic links at your disposal. The following transmission modules are currently available - more information in the group Offer > Products > Components > MS system modules
Some configurations of communication controllers require direct acquisition of information from binary inputs from station devices and issuing binary signals to retransmission and station devices. Binary inputs/outputs are also necessary to implement station interlocks, signaling and cooperation with some types of protections and disturbance recorders.
Individual modules of the SO-55 controller are managed by the central unit (PJC-xxx). The central unit communicates with other modules via the MS bus. It is also possible to communicate with packets equipped with the LVDS bus thanks to a dedicated fast serial transmission channel. Additional information on central units is available in the group Offer > Products > Components > MS system modules > PJC-86x 
The SO-52v11-eMW breaker module is designed to control the breaker at 110kV, 220kV and 400kV substations. The control is carried out with the use of automatic re-closing (reclosing) or manually. When switching on, it is possible to use the synchronism module, which, depending on the current voltage, phase and frequency conditions, enables the circuit breaker to be closed at the most favorable moment. Standardized communication protocols have been implemented in the device, which enables full cooperation with master systems of various manufacturers.
The device performs the following functions:
The breaker module has a modular structure. It is enclosed in a cassette housing with IP50 tightness class. Depending on the field type, which determines the number of required inputs/outputs, the number of binary input/output modules may be different. The example configuration consists of the following modules:
The structure of the device in the full cast of packages is shown on the right.
The MPA-408-21 measurement and communication module performs measurements, calculations and network or serial transmission with external communication controllers or superior systems.

The MSS-328 control output module performs the necessary controls in the breaker module system. It is adapted to implement high-current controls. The maximum control current is 5A/220V DC.
The MSS-618 control output modules are used to implement indirect control of primary devices. The outputs of the modules can also be used to implement signaling systems and bay, inter-bay and station interlocks. 
The SO-52v21-PC-xx controller is designed to work in medium voltage networks. It supports the optimal selection of the network operating point by controlling the Petersen coil. The selection of the MV network operating point is carried out by appropriate compensation of the network capacitive current. Thanks to this, in the case of a single-phase fault to earth, a low resultant earth-fault current appears, which is conducive to fast extinguishing of the arc. In the event of a transient short-circuit, the fault will be automatically eliminated and the electricity supply will be uninterrupted. The controller collects data and processes it into information. It also supports transmission protocols and all logical operations performed in the controller's internal database. The controller is equipped with modules in. measuring devices as well as binary inputs and outputs, and a power supply. It may have an SD card for recording quantities and events related to the implemented functions, operation of the controller, transmission status and diagnostic functions.
