An I/O server is an application that communicates with and manages input and output devices such as programmable logic controllers (PLCs), remote input/output devices, remote Shared Variable Engines, and data acquisition (DAQ) plug-in devices. These I/O servers read selected input items and write to the selected output items on demand.
Right-click an I/O server on the system tree to display the following options.
- Watch List—Creates a new Watch List view that contains the single variable or multiple variables contained within the selected system or process.
- Probe—Displays the I/O Server Probe view for the selected system.

- Remove I/O Server—Removes the selected I/O server.
