Electronic protocol converter  (EPC)

Autonomous component part MCSU — EPC
Brief technical characteristics of the device for converting non-standard teleinformation exchange protocols to one of the international standard protocols (EPC)
1. Technical characteristics:
— made on the basis of a module from the STM family of industrial controllers of the STM-32F4 type;
— basic operating system FREE RTOS;
— Ethernet 10/100 Base – 1 or 2;
— four duplex channels with RS-485 interfaces for data exchange using standard asynchronous protocols at speeds ranging from 9600 to 57600 baud;
— design execution – plastic case with mounting on a DIN rail;
— overall dimensions 150x70x110 mm, complete with a mounting bar with fasteners for installation on a DIN rail;
— mechanical protection — IP20;
— External connections using:
a) to the computer network – RJ-45 connector;
b) up to 4 digital dedicated channels with RS-485 interface — 3P connector;
— service LEDs are installed on two side walls of the case, which reflect the presence of secondary power supply voltages and the operating status of both the device itself and data exchange through the communication channels involved.2. List of performed functions:
− cyclic polling of subordinate devices regarding the data of TC, TI;
— cyclic transfer of TK, TI data without requests;
− synchronization of own system clock by the control server;
— reception of TU commands from the control server and their retransmission to the corresponding subordinate device;
− temporary archiving of operational information in case of loss of communication channel with the control server;
— issuance, at the request of the control server, of the full volume of information on the collected values of parameters of the vehicle, TI;
− setting of insensitivity zones for TI parameters;
− setting the parameters of TV information exchange channels;

−supports exchange using specialized protocols, such as:

     Modbus RTU Serial (Master/Slave);
     IEC60870-5-104 (———/Slave);

− real-time data exchange support with 30 subordinate devices;

− control of communication parameters with a subordinate device, formation of service logic signals regarding the working status and quality of communication;
− updating configuration parameters and built-in software remotely via USB;
— service software for configuration under conditions on the EKPconfig object.
3. Operating characteristics:
— work in closed premises with a high level of danger;
− ambient temperature from minus 20 to 50 °C;
− power supply voltage 24 V DC, power consumption up to 8 W;
— warranty period of 36 months;
— warranty period of 12 years.
Note. EKP is a component of the MKSU product (TU U 31.2-25641912-001: 2011) and can be supplied as a separate device.
