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.
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.

Energy metering solutions market has been recognized for a long time as a segment with a maximum number of various data exchange protocols used. Despite the fact that each meter type measures similar network parameters, most manufacturers use proprietary exchange protocols. To solve the problem of consolidating various devices into a single management solution, DLMS (Device Language Message Specification) protocol was developed and became a new industry standard.
I use the OPC Server as part of a dispatch system for an individual heat point in a business center. The program works with controllers via RS-232 ports. This solution has a lot of advantages. Remote parameter monitoring is available. The created system provides convenient...
We bought the OPC Server and OPC Client about three years ago. We decided to modernize the pumping station. In this regard, we had to improve the performance of the control room. Previously, our employees made the rounds every half an hour: they recorded water meter...
