Device Replacement Without Removable Medium/Programming Device; Shared Device - Siemens SIMATIC S7-400H System Manual

8.5 Device replacement without removable medium/programming
device
IO devices having this function can be replaced in a simple manner:
● A removable medium (e.g. SIMATIC Micro Memory Card) with stored device name is not
● The PN-IO topology must be configured in STEP 7.
● The device name does not have to be assigned with the programming device.
Before reusing IO devices that you already had in operation, reset these to factory settings.

Shared Device

The "Shared Device" functionality facilitates distribution of the submodules of an IO device to
different IO controllers. An intelligent IO device can also be operated as shared device.
Prerequisite for using the "Shared Device" function is that the IO controller and shared
device are located on the same Ethernet subnet.
The IO controllers can be located in the same or different STEP 7 projects. If they are
located in the same STEP 7 project, a consistency check is initiated automatically.
Note
Note that the power modules and electronic modules belonging to the same potential group
of a shared IO device (e.g. ET 200S) must be assigned to the same IO controller in order to
enable the diagnosis of load voltage failure.

8.5 Device replacement without removable medium/programming device

required.
The replacement IO device is now assigned a device name from the IO controller. It is no
longer assigned using a removable medium or programming device. The IO controller
uses the configured topology and the relations determined by the IO devices. The
configured target topology must match the actual topology.
