OPC Server to communicate with PLC Siemens©. S7-200™, S7-300™, S7-400™, the new S7-1200™ and LOGO™, inverter SINVERT™ on Ethernet network!

An OPC Server of the last generation ideal for monitoring the three-phase solar inverter model Siemens Sinvert™..

The Marcom OPC Server UA S7.NET has high performance and wide ease to use. As a leading supplier of OPC products, Marcom is proud to distribute the product much better on the market of OPC products for the communication with the way Siemens:

  • High performance: the communication on Ethernet network allows to reach high speed of data exchange
  • Easy and immediate configuration: ensures high speed of commissioning
  • Extremely convenient: a system of sizes to fit any requirement

The Marcom OPC Server UA S7.NET allows to quickly and compfortably access to process data in the controllers S7-200 (via CP-243), S7-300, S7-400, S7-1200 e LOGO, utilizing a single server. The variables are constantly adressed utilizing the STEP7 semantic, own development environments Siemens. 
With any client application that is compatible with the OPC specifications will be read and write all the input and output data, datablock and merker. Is possible to access simultaneously to an unlimited number* of controller.

( *: The number of reachable controller is determined by the resourses of the machine and by the network's topology)
For the communication with the Marcom OPC Server S7.NET is not necessary to modify the program. The access to the controllers can be made directly via Ethernet. 
An intelligent algorithm of reading and writing requests management allows to optimized data throughput in a extremely efficiently way: the block reading allows a refresh data without equal.
The configuration is made through a convenient graphic interface, either manually or thanks to a tool for importing of symbolic names from STEP7 projects or from Excel file. Existing configuration for example can be esported to Excel from visualization systems or process control in order to be conveniently loaded on Marcom OPC Server S7.NET.
