Quick access to S7/S5 data with 32/64-bit PC architecture
In the S7/S5 OPC server from version 4.10, the number of supported operating systems has been extended. It provides quick and convenient access to the process data of your PLCs.
After installation on a Windows PC (XP/2003/Vista/2007/2008), the standardized OPC interface is available for data exchange with the following controllers, among others: S7-200*/300*/400*/1200*/1500*, LOGO! 0BA7, WinAC*, C7, and S5-CPUs of the U series.
In this way any OPC-compliant client application can read and write the required input/output data, data blocks, markers, timers, and counters into the S7/S5 controllers.
Addressing of the variables is consistently carried out in the familiar S7 semantics and can, if desired, be imported directly from an Excel file or an S7 project.
An existing control program in your PLC does not need to be adapted for communication with the S7/S5 OPC server. This means that no detailed knowledge about the specific PLC program is required.
For connecting your controllers to the S7/S5 OPC server, there are a variety of options available, such as TCP/IP, PROFIBUS, MPI, PPI, or AS511. In the S7/S5 OPC server configuration menu, up to 16 communication devices can be activated, with which parallel data exchange can then be implemented. Using the communication protocol TCP/IP (RFC1006), simultaneous access to up to 256 controllers is also possible in the maximum expansion stage.
For communication, Helmholz offers the following communication adapters:
• All products in the REX and NETL ink® family
• SSW7, SSW7-TS, SSW7-USB for MPI
• SSW3, SSW4 and SSW5 for AS511
Some communication modules from other manufacturers, such as Siemens CP 243, 343, and 443, are also supported. Through improved license management, the USB driver supplied with the hardware dongle has been optimized for use in virtual machines (vmware***, ESX***, etc.).
Integrated web server
The S7/S5 OPC server has a built-in web server. This can be used for diagnosing the OPC server functions as well as for providing their own websites for operation and monitoring using any standard browser.
The architecture and performance of the Web server is designed for smaller visualizations.
In addition to supporting OPC Data Access 1.0a, 2.05, and 3.0, starting with this version non-Windows-based applications can use the S7/S5 OPC server using OPC XML DA.
The current OPC server version** (incl. all technical information) is available for download.
