Communication Drivers
SFBERPVI
B&RSFBERPVI is aDLL driver that allows a Super-Flash application to manage communication with B&R automation devices via PVI (Process Visualization Interface).


Architettura

The DLL driver is placed in the group of PVICOM Applications, directly interfaced with the PVICOM Interface.
In order to configure and use the driver correctly, an in-depth knowledge of the B&R PVI environment is necessary: in the manual, in all the points where the driver interfaces with PVI, reference is made to the B&R manual for implementation details.
The advantages of SFBERPVI
Effective
The use of the SFBERPVI driver is one of the most effective solutions on the market. The driver connects, as a PVIcom application, to the PVI software that virtualizes the network of B&R devices..
Economical
It is possible to purchase the driver in Runtime version; the license can be used for a single application.

Description
SFBERPVI is a DLL driver that allows a Super-Flash application to manage communication with B&R automation devices via PVI (Process Visualization Interface).
Characteristics
SFBERPVI allows to manage:
  1. communication with muliple PLCs
  2. retries on the single channel in case of communication error
  3. inactivity time on the single channel in case of communication error
  4. read/write of boolean (1 bit) type resorces in single or array mode
  5. read/write of u8 (8 bit) type resorces in single or array mode
  6. read/write of i16 (16 bit) type resorces in single or array mode
  7. read/write of i32 (32 bit) type resorces in single or array mode
  8. read/write of f32 (32 bit) type resorces in single or array mode
  9. read/write o fstring type resorces in single mode
Limits
SFBERPVI has the following limits:
  1. i64 type is not managed
  2. u16 type is not managed
  3. u32 type is not managed
  4. u64 type is not managed
  5. f64 type is not managed
  6. string type in array mode is not managed
  7. wstring type is not managed
  8. struct type is not managed
  9. time type is not managed
  10. dt type is not managed
  11. date type is not managed
  12. tod type is not managed
  13. data type is not managed
  14. If used in a Super-Flash application version 4.1 or earlier, the maximum length of a PVI variable is 12 characters
  15. arrays can be managed only starting from element 0, for a number of elements less than or equal to the size of the array on the PLC
  16. for arrays it is possible to extract from the block only elements of the exact size of the object (for example, it is not possible to extract from an array of i16 only one byte, but only the single word)
  17. for arrays, in case of management of number of elements less than the array size, it will not be possible to write the whole variable, but only the single extracted elements
  18. for the string type, the size of the variable in Super-Flash must be less than or equal to the size of the string variable of the PLC (VL=) minus one (terminator character))
Skills
SFBERPVI requires the following skills for use:
  1. use of LINK DRIVER in SUPER FLASH
  2. knowledge of B&R PVI system
  3. minimal knowledge of PLCs database
Minimum Requirements
  1. Windows 9X, NT4, 2000/XP operating systems
  2. WRunfile 3.2
  3. PVI Manager installed on the application PC or in the network
