Communication Drivers
Super-Flash OPC-UAC
Super-Flash OPC-UACSuper-Flash OPC-UAC is a communication driver which allows connection of the WRunfile engine of Super-Flash with OPC UA servers.

By means of the configuration tools it is possible to browse the servers and the elements available on the network and make them visible for the archive of Super-Flash variables.

OPC UA is the interoperability standard for secure and reliable data exchange in the industrial automation and other sectors. It is platform independent and ensures the seamless flow of information between devices from multiple vendors.
The advantages of Super-Flash OPC-UAC
Simple
The use of Super-Flash OPC-UAC is definitely simpler, especially in the configuration phase where the software allows browsing of the items supplied by the OPC Servers connected in the network.
Flexible
Thanks to use of the standard OPC technology, Super-Flash OPC-UAC allows Super-Flash to communicate with a wide range of peripherals of different companies and in various models.
Economical
 It is possible to purchase the driver in Runtime version; the license can be used for a single application.

  1. connection to an unlimited number of OPC UA servers
  2. server discovery on host
  3. connection mode:
    1. Transport: UA-TCP UA-SC UA-Binary
    2. Security policy: None, Basic256, Aes128-Sha256-RsaOaep, Basic256Sha256, Aes256-Sha256-RsaPss
    3. User Authentication: Anonymous, UserName
    4. Management of self-signed certificates
  4. "Data Access" service
    1. reading and writing of the following data types:
      • Boolean as single value and array (*)
      • Byte and SByte as single value and array (*)
      • UInt16 and Int16 as single value and array (*)
      • UInt32 and Int32 as single value and array (*)
      • Float as single value and array (*)
      • Double as single value and array (*)
      • String as single value and array (**)
      • ByteString as single value and array (**)
      • LocalizedText (only 'Default language') as single value and array (**)
    2. Reading of optional information:
      • Data quality
      • server timestamp
      • source timestamp
    3. write management in "SafeWrite" mode
    4. array writing with "IndexRange" mode
    5. monitor of value changes (DataChange Subscriber)
  5. "Method call" service (only with .NET interface) (***)

(*) monodimensional array only
(**) each element must be managed with a variable
(***) for input/output parameter values, the same type limits apply as for "Data Access" service
