Level
transmitter
Min. level 50 l.
When the level falls below
this, a message is to be
output at output Q9.2
(Q 5.2).
Max. level of 600 l,
equals 10 V at
analog channel 0

Exercise: Diagnostic Interrupt from an Analog Module
Analog input module
When the value measured at an analog
channel of the module exceeds the
overflow range, OB82 is called, as well
as when it re-enters the range.
Rated range
Overrange
Overflow
Task:
Output Q 9.1 (Q 5.1) is to flash as long
as one of the encoded values is in the
overflow range.
