Evaluating the value status
If you enable the value status for the digital module, a byte in the input address space is
additionally assigned. Bits 0 to 3 of this byte are each assigned to one channel. They provide
information about the validity of the digital value.
Bit = 1: No error is present on the channel.
Bit = 0: Channel is disabled or there is an error in the module.
If an error occurs on a channel of this module, the value status for all channels is 0.
