Address space
Address space with value status (Quality Information, QI)
The figure below shows the assignment of the address space with value status (Quality
Information (QI)). "IB x" represents the start address of input byte x.
The addresses for the value status are only available if the value status is enabled.
Figure 3-4 Address space with value status
Evaluating the value status
An additional byte is allocated in the input address space if you enable the value status for
the digital module. Bits 0 to 7 in this byte are each assigned to a channel. They provide
information about the validity of the digital value.
Bit = 1: No fault is present on the channel.
Bit = 0: Channel is disabled or there is a fault/error on the module.
If a fault/error occurs on a channel with this module, the value status for all channels is 0.
