Communicating with Experion via OPC UA
Experion server to ControlEdge 900 Controller communication is
with the OPC UA protocol, so the OPC UA Server must be enabled on
the Ethernet port(s) connected to the same network as the Experion
Server.
Experion can read, write and monitor global variable, program local
variable and function block instance variable through the Identifier
defined by OPC UA protocol. The maximum length of the Identifier is
73 characters.
Global variable's Identifier is @GV. <Varname>.
Program local variable's Identifier is <Program Instance
Name>.<Varname>.
Function block instance variable's Identifier is <Program Instance
Name>.<Function Block Instance>.<Varname>.
For more details about the Experion integration with ControlEdge
900 controller, see the
