The Delphi software products offer programming interfaces for Delphi developments with access to PROFIBUS.

The following protocols are available:

• PROFIBUS DP (Delphi-DPLib)
  for the DP-5613 software with CP 5613 A2/CP 5614 A2 or
  SOFTNET-DP with CP 5512, CP 5611 A2 or CP 5621
• PROFIBUS DP SOFTNET slave (Delphi-DPSoftnetSlave)
  for all SIMATIC DP slave products for CP 5611 A2 or CP 5621
• S7 communication (Delphi-S7)
  for the S7-5613 software with CP 5613 A2/CP 5614 A2
  or SOFTNET-S7 with CP 5512/CP 5611 A2 or CP 5621

The products enable easy access to the Siemens SIMATIC NET programming interfaces under Borland Delphi.

In its communication functions, the interface for Borland Delphi is analogous to the Siemens interface for the programming language C. All the services of the relevant communication protocols over PROFIBUS are supported.
