Useful information on shared devices
Shared device functionality
Numerous IO controllers are often used in larger or widely distributed systems.
Without the "Shared Device" function, each I/O module of an IO device is assigned to the
same IO controller. If sensors that are physically close to each other must provide data to
different IO controllers, several IO devices are required.
The "Shared Device" function allows the modules or submodules of an IO device to be divided
up among different IO controllers. Thus allowing flexible automation concepts. You have, for
example, the possibility of combining I/O modules lying near other into an IO device.
