Protocols

Modbus is an open industrial protocol. Three modifications of Modbus are available: Modbus RTU, ASCII and TCP. The following interfaces can be used for Modbus-based data transfer:

·        RS-232 or RS-485 

·        GSM or radio-channels

·        Various TCP/IP channels (Ethernet, Wi-Fi, GPRS)

Modbus protocol featured by its light transfer method and fast operation, and this makes it the most popular industrial protocol.

The BACnet protocol is applied in large automation systems of buildings or complexes (shopping centers, business centers, airports, etc.). One of the most important BACnet features is a high degree of versatility and flexibility: the protocol supports a large number of objects and data types, and provides a poll of various physical parameters.
Profinet is an extension of the Profibus protocol for communication over Ethernet. This protocol is applied in Siemens controllers and other manufacturers.
SNMP is an Internet-standard protocol for managing devices on IP networks. It operates on UDP/TCP protocols of the transport layer of network architectures. SNMP is commonly used to monitor various network devices (routers, multiplexers, servers, workstations, UPSs, etc).
IEC 60870-5-104 protocol is used in large-scale TCP/IP networks in telemetry systems. The protocol major applications are found in power generation and oil and gas transportation industries.

IEC61850 MasterOPC Server is an OPC server destined to operate with any equipment that supports data exchange via the IEC 61850 protocol. Such equipment is most often used for monitoring parameters of electrical current in power plants. Due to wide use of the protocol, the OPC server is tested on various hardware configurations that are typical for substations (SIEMENS, ABB, AREVA, GE, SATEC, etc.) Stress test of the server showed its high performance and possibility of lossless transmission of short pulse signals.

Omron Corporation is one of leaders of Japanese instrument making industry. For over 70 years, the corporation has been producing a variety of products in such fields as electronic components, PLCs, automotive and medical electronics. Omron PLCs are widely used in various of fields, especially in assembly lines, machines, batching systems, etc. The controllers have established themselves as high-performance, reliable, functional and affordable solutions. In Omron networks, the controllers use the FINS protocol to communicate between themselves. FINS is an open communication protocol. The most of controllers and networks of Omron support that protocol. The FINS protocol operates in Ethernet networks (via the UDP transport protocol) as well as over serial communication channels (RS-232, RS-485 or GSM). Omron MasterOPC Server is destined to integrate Omron equipment into systems of automation and dispatching via the FINS protocol. The server is implemented as a plugin for Multi-Protocol MasterOPC Server.

The SCRIPT plugin of Multi-Protocol MasterOPC Server is provided for programming of devices in the built-in programming language based on the LUA script language. The built-in programming language allows you to solve such tasks as development of own protocols, creation of device simulators, data processing, or interaction with external programs. 

The OPC DA Client plugin of Multi-Protocol MaterOPC Server provides connection to and data acquisition from OPC DA/HDA servers.

Mitsubishi Electric is one of the divisions of Mitsubishi Japanese conglomerate. Mitsubishi MELSEC-branded programmable logic controllers are known for their high reliability and performance for almost 40 years! MELSEC PLCs are among the best-selling in the world. Mitsubishi MasterOPC Server allows to integrate Mitsubishi controllers with automation and supervision systems without using gateways and third-party software. An open proprietary SLMP protocol is used (also called MC protocol) is used for data transfer between Mitsubishi PLC and upper layer.
