S7A Driver

The S7A Driver/OPC Server is one of the leading and most powerful I/O Driver and OPC Server for the Siemens Simatic S7 PLC family and for the generic PROFIBUS and PROFINET protocol. It has proven its value over the past 10 years in thousands of installations as:

  • Proficy iFIX I/O Driver
  • Proficy Cimplicity I/O Driver
  • OPC Server

The advantages of the S7A Driverr/OPC Server are as follows:

  • No additional software license such as Prodave or Softnet-S7 is required
  • Quick and easy configuration
  • Usable for the whole S7 PLC family
  • All available S7 interfaces (serial, MPI, Profibus and Ethernet) will be covered by a single driver
  • Generic PROFIBUS and PROFINET interface
  • Build-in data monitor and online display facilitates commissioning and maintenance
  • Simultaneous operation as iFXI/Cimplicity driver and OPC server

Supported Application software

For use with GE’s Proficy products the S7A driver features the native high-performance interfaces to both of their SCADA products namely iFIX and Cimplicity HMI. Especially in large SCADA applications with tens of thousands of I/O points the native interfaces are offering essential performance advantages compared to an OPC Server-Client solution.

  • FIX32/iFIX all versions
  • Cimplicity HMI versions 8.0, 8.1, 8.2, 9.0 and 9.5
  • OPC DA Clients supporting OPC Spec. DA 1.0 or 2.05
  • HMI/SCADA-Systeme which offer an OPC DA Client interface such as InTouch HMI or ControlMaestro

Supported Hardware

The S7A Driver/OPC Server supports the whole Siemens Simatic S7 product family. The new S7-1200 CPUs as well as the new S7-1500 controller family can be connected to the S7A Driver. Furthermore redundand S7-400H controller pairs are supported by a set of special functions which allows the driver to detect the currently active master CPU.
The following diagram shows an overview of all the supported protocols and hardware.
