Value status (Quality Information, QI)
The meaning of the value status depends on the submodule to which it pertains.
With basic submodule (= 1st submodule), the "0" value status indicates that the value is
incorrect.
With MSO submodule (= 2nd to 4th submodule) the "0" value status indicates that the value
is incorrect or one of the following errors has occurred:
● The basic submodule parameters have not yet been assigned (not ready for operation).
● The connection between the IO controller and the basic submodule has been interrupted.
● The IO controller of the basic submodule is in STOP or POWER OFF state.
