Diagnostics: Overflow channel n
Enabling of the diagnostics when the measured value exceeds the overrange.
Diagnostics: Overflow/Underflow (for PROFIBUS only)
Enabling of the diagnostics when the measured value exceeds the overrange or falls below
the underrange.
The diagnostic enable has an effect on all channels.
Hardware interrupt high/low limit 1 or 2 channel n
Enabling of a hardware interrupt when the high limit 1 or 2 or the low limit 1 or 2 is violated.
Requirement: An OB 4x must be assigned to the CPU/device.
Additional information on the structure of hardware interrupts is available in the section
Interrupts (Page 33).
High/low limit 1 or 2 channel n
Specify a threshold at which a hardware interrupt is triggered when it is exceeded or
undershot.
4.4 Address space
The figure below shows the assignment of the address space for the analog input module
AI 4xU/I/RTD 4xM12 with value status (Quality Information, QI). If you are using PROFINET
and the value status was enabled, the addresses for the value status are available. The value
status is not available for PROFIBUS.
