Trigger Error OB Command (Execute Menu)

Top 

The menu command Execute > Trigger Error OB allows you to test how your program handles different interrupt OBs. S7-PLCSIM supports the following:

Hardware Interrupt (OB40-OB47)...

I/O Redundancy Error (OB70)...

CPU Redundancy Error (OB72)...

Communication Error (OB73)...

Time Error (OB80)...

Diagnostic Interrupt (OB82)...

Insert/Remove Module Interrupt (OB83)...

Priority Class Error (OB85)...

Rack Failure (OB86)...

Making any of these selections opens a dialog box where you enter the necessary data for the simulation of that OB.
