Address space for configuration as 1 x 16-channel DI 16x24VDC BA MSI
The channels 0 to 15 of the module are copied to up to 4 submodules with configuration 1 x
16-channel module (Module-internal Shared Input, MSI). Channels 0 to 15 are then available
with identical input values in different submodules. These submodules can be assigned to up
to four IO controllers when the module is used in a Shared Device. Each IO controller has
read access to the same channels.
The number of usable submodules depends on the interface module used. Please observe
the information in the manual for the particular interface module.
Value status (Quality Information, QI)
The meaning of the value status depends on the submodule involved.
For the 1st submodule (=basic submodule), the value status is not relevant.
For the 2nd to 4th submodule (=MSI submodule), the value status 0 indicates that the value
is incorrect or the basic submodule has not yet been configured (not ready for operation).
The figure below shows the assignment of the address space with submodules 1 and 2.
