Communication Drivers
SFNetLink
SFNetLinkSFNetLink is a DLL driver which allows to a Super-Flash application to communicate in MPI and PROFIBUS with SIEMENS S7 300/400 PLCs via the Hilscher Ethernet NetLink gateway.

The choice of using such a driver is ideal for those who want a solution with good performance.
The advantages of SFNetLink
Affordable
Using the SFNetLink driver does not involve inserting any hardware components into the CPU.
Operational
The SFNetLink driver offers another interesting added value: it allows you to use the same PC board to program PLCs in Step 7.
Economical
It is possible to purchase the driver in Runtime version; the license can be used for a single application.
Technical card of SFNetLink 1.1 SP2
Description
The SFNetLink driver allows a Super-Flash application to manage communication with the SIEMENS S7 300/400 PLCs via the Hilscher NetLink Ethernet Gateways and makes it possible to interface with the SIEMENS MPI network with an Ethernet TCP/IP connection.
Characteristics
SFNetLink allows you to manage:
  1. communication with up to 256 SIEMENS S7 PLCs
  2. retries on the single node in case of communication error
  3. inactivity time on the single node in case of communication error
  4. read of Input (8, 16, 32 bit) type in single or array mode
  5. read/write of Output (8, 16, 32 bit) type in single or array mode
  6. read/write of Merker Integer (8, 16, 32 bit) type in single or array mode
  7. read/write of Merker Floating Point (32 bit floating point) type in single or array mode
  8. read/write of DataBlock Integer (8, 16, 32 bit) type in single or array mode
  9. read/write of DataBlock Floating Point (32 bit floating point) type in single or array mode
Limits
  1. Timer type is not managed
  2. Counter type is not managed
  3. the maximum number of SIEMENS S7 PLCs in direct Ethernet TCP/IP connection to which you can connect is 32
  4. the connection of more than one SUPER FLASH client to the NetLINK-MPI Gateway (basic model) can generate communication errors, especially when communicating with more than one PLC.
Minimum Requirements
