Interrupts - hardware interrupt
Process faults, warnings, and status information are interrupt sources for hardware
interrupts.
As soon as SIMOCODE pro sets a hardware interrupt, the hardware interrupt OB 40 will be
started in the SIMATIC S7.
Hardware interrupt - structure
The hardware interrupt has the following structure:
Figure 2-9 Structure of the hardware interrupt
The first byte of the block for hardware interrupts can be shifted by 3 or 6 bytes depending
on the number of blocks for channel-related diagnostics.
The detailed messages can be found in Chapter "Detailed messages of the slave
diagnostics" in Chapter Detailed messages of the slave diagnostics (Page 153).
