To define an I/O Server, you need to specify a name on the I/O Server form. This name will be used to reference the I/O Server and has to be logical. For example, for a single I/O Server, you might use the name IOServer. When specifying the server name, you cannot use localized characters. See I/O Server Definitions.
If you are using multiple I/O Servers for redundancy (or to split the communications), you need to add a database record for each. Select a unique name for each I/O Server, for example IOServer1 and IOServer2.
Note: You need to add the record to the project database (use the Add Button at the bottom of the form) or replace the record (use the Replace Button at the bottom of the form) if you have changed the record.
