Issue
Some of the devices on a serial daisy chain need to live on a different I/O Server than the rest of the devices on that daisy chain.
Product Line
Power SCADA Operation 9.0
Environment
Studio, Topology, PSO server
Cause
In PSO, a specific Port cannot be used on more than one I/O Server.
Resolution
To split a daisy chain between multiple I/O Servers, a unique Port is needed for each I/O Server. For example, assume a daisy chain of 10 devices needs 5 serial devices on I/O Server 1, and the other 5 on I/O Server 2. The port for the 5 serial devices on I/O Server 1 is named North_IO1_devices. A second unique port needs to be defined for the devices that will exist on I/O Server 2, perhaps named South_IO2_devices.

- This port can be created for I/O Server 2 in the Ports table located in Topology > Components and Mapping. The IP address will be the same for both ports since it is the same gateway device/daisy chain.
- Once the Port is created, Navigate to Topology > IO Devices. Assign the newly created port to the desired devices for I/O Server 2, and change the I/O Server fetid for each device to the appropriate name.
- Save and compile the project.
