Evaluating Interrupts with an S7 DP Master or DPV1 Master
Requirement: You have configured the ET 200iS with STEP 7 (Version 5.1, Service
Pack 2, Hotfix 1 or higher) or PCS 7 (Version 5.2 or higher); in other words,
interrupts are only supported if the ET 200iS functions as an S7-DP slave or DPV1
slave.
If an interrupt occurs, interrupt LPs are called automatically in the CPU of the DP
master (see programming manual System Software for S7-300/S7-400, Program
Design).
Evaluating Interrupts with Other DP Masters
If you operate the ET 200iS with a different DP master or as a DP standard slave,
no interrupts are generated.
Triggering a Diagnostic Interrupt
When an event (for example wire break) enters all leaves the state, the module
triggers a diagnostic interrupt if "Enable: Diagnostic interrupt“ is set.
The CPU interrupts execution of the user program and runs the diagnostic block
OB82. The event that led to the interrupt been triggered is entered in the startup
information of OB82.
Triggering a Hardware Interrupt
If a hardware interrupt occurs, the CPU interrupts execution of the user program
and runs the hardware interrupt block OB40.
The channel of the module that triggered the hardware interrupt is entered in the
startup information of OB40 in the variable OB40_POINT_ADDR. The schematic
below shows the assignment to the bits of the local data double word 8.
