MasterOPC Universal Modbus Server is an OPC server for applications that communicate using the popular industrial protocol Modbus. The product supports the following Modbus modifications:
Modbus RTU (including SLAVE)
Modbus ASCII
Modbus TCP/IP (including SLAVE)
Modbus over TCP (support of Ethernet-COM converters)
MasterOPC Universal Modbus OPC Server has the following distinctive features:
Built-in textual programming editor that essentially expands the product functionality
Group operations on variables and Import of previously configured OPC tree device components and variables which grant a fast and easy way to create analogous new device configurations
Redundancy: Increased Polling Reliability
MQTT: Integration with IoT Devices and Cloud Services
ODBC: Databases Connection
MasterOPC Universal Modbus Server is an OPC server for Modbus RTU/ASCII/TCP industrial applications. The Modbus OPC server provides two OPC interfaces: DA (Data Access, processed data) and HDA (Historical Data Access, archived data). To organize the storage of archived variables data MasterOPC uses the built-in SQL server.
The built-in programming editor provides additional processing on data received from external devices as well as processing of data being sent to external devices. Processing variables via scripts using the built-in programming language is as well essential for other equally important purposes. Using the scripting utility you can:
Scripts can be applied at any level in the OPC tree (communication nodes, devices, sub-devices or tags). The built-in editor provides other standard services such as keyword highlight, convenient work with tags or libraries, etc.
The server by default supports other typical operations on tags such as: automatic type casting, conversion to real measurement units, byte swapping, bit extraction, etc.
MasterOPC supports communication over GSM or other modem connections. This allows it to be used in supervisory control and/or data acquisition systems. MasterOPC can operate as well as a TCP server; this allows an effective use of MasterOPC together with GPRS/3G gateways without using static IP addressing mode. For diagnostic purposes, during run-time MasterOPC logs and displays data transfer detailed events from driver or from script generators as user friendly messages and as Modbus protocol data units messages which help users of different qualification levels to track data transfer events.
Redundancy of communication channels
Redundancy allows you to create highly reliable connections with controllers and equipment.
Feature highlights:
MQTT protocol support.
MQTT protocol is designed for communication with IoT devices (IoT stands for Internet of Things) and integration with cloud services (Microsoft Azure, Amazon Web Services, etc.). This functionality allows you to send and receive data from OPC servers in various cloud applications.
Feature highlights:
ODBC technology support.
ODBC technology provides integration with various DBMS (MS SQL, Oracle, MySQL, PostgreSQL, etc.). Built-in script editor exposes additional functionality to process data returned by an arbitrary SQL query. This makes integration of OPC server with applications that do not support OPC natively such as MES, ERP and BI systems a breeze.
Feature highlights:
IEC 60870-5-104 is an industry protocol mainly used in the Energy and Oil & Gas industries. Our OPC server supports IEC104 mode. This mode allows for an OPC server adapter from Modbus to IEC104 protocol while supporting other interfaces (OPC DA, UA, ODBC and MQTT).
Feature highlights:
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...
