Interrupt blocks with DPV1 functionality
Table 3-13 Interrupt blocks with DPV1 functionality
OB Functionality
OB 40 Process interrupt
OB 55 Status interrupt
OB 56 Update interrupt
OB 57 Vendor-specific interrupt
OB 82 Diagnostic interrupt
Note
You can now also use organizational blocks OB40 and OB82 for DPV1 interrupts.
System blocks with DPV1 functionality
Table 3-14 System function blocks with DPV1 functionality
SFB Functionality
SFB 52 Read data record from DP slave or centralized module
SFB 53 Write data record to DP slave or centralized module
SFB 54 Read additional alarm information from a DP slave or a centralized module in the
relevant OB.
SFB 75 Set any interrupts for intelligent slaves
Note
You can also use SFB 52 to SFB 54 for centralized I/O modules. SFBs 52 to 54 can also be
used for PN IO.
