Shared Device Functionality

DeviceMaster PNIO | UP User Guide: 2000639 Rev. A
The DeviceMaster supports the shared device functionality, which allows two IO
controllers to access different serial ports or Ethernet devices through the same
gateway simultaneously.
Assuming we have a PNIO-2304 and two IO controllers. IO Controller 1 wants to
access two serial devices connected to Serial Port 1 and 2. IO Controller 2 wants to
access a third serial device connected to Serial Port 3. Separate TIA Portal projects
need to be created for the two IO controllers.
The first IO controller is considered as the main PLC.
1. Create a new TIA Portal project.
2. Add the PLC1 and the PNIO-2304.
3. Insert two serial modules in Slot 1 and Slot 2 for the two serial devices.
4. Configure the IO submodules.
5. Compile and download the project to PLC1.
6. Check the Diagnostics | System Info page to confirm that an application
relationship has been established between the DeviceMaster and PLC1.
The second IO controller is considered as the secondary PLC and needs special
configurations.
1. Create a second TIA Portal project.
2. Add the PLC2 and the PNIO-2304.
3. Name the PLC2 as PLC_2, as shown in the following figure.
4. Configure the PLC2 with a different IP address as the PLC1.
5. Configure the DeviceMaster with the same IP assignment and device name as
the first project.
