3.3.2   Comport Properties

Comport is an abbreviation for "communications port".   The Comport is the physical or virtual link from your SCADA node to the automation device. Virtual Links include DDE, OPC and API interfaces which are actually communications to software (a DDE Server, an OPC Server or an Application Programming Interface). TCP/IP also uses a virtual comport; WebAccess will search all TCP/IP network cards regardless of Comport number assigned.
