11.8 Access to diagnostic data
11.8.1 Acyclic Access
If the interrupt has been activated via the parameterization in the correspond-
ing module or in the Cube20S PROFINET IO device, Cube20S modules ca-
pable of triggering interrupts automatically send process diagnostic interrupt
data to the master system.
The functional block SFB 52 - RDREC can be used to read the diagnostic
data sent last in an acyclic manner from the module.
11.8.2 Diagnostic data of PROFINET IO device
Using slot = 0 / subslot = 1 access the PROFINET IO device.
Depending on the index you receive the following data back:
Index = 0x0000: 4 bytes
Byte 0: diagnostic byte 1
Byte 1: diagnostic byte 2
Bytes 2 ... 3: 0 (fixed)
Index = 0x0001: 20 bytes
Byte 0: diagnostic byte 1
Bytes 1 ... 19: 0 (fixed)
