Status Display Function Features of the Status Display function are as follows: • Executable Function Status Display Practice status display (stopped, running as a service, running as a process).
3.2 1 Detailed Description of Functions OPC Server GateOPC utilizes the OPC (OLE for process control) DA (data access) revision 2.0 server and COM/DCOM technology on the local machine or remote machine to form a connection and acquire data. 3 Interfaces Used Detailed Description of Functions The interfaces for the OPC server are defined as shown in the figures below.
3.2 Detailed Description of Functions The interfaces used by GateOPC are as follows: • OPC Server Object IOPCCommon IOPCServer IOPCItemProperties IConnectionPointContainer IOPCBrowseServerAddressSpace • OPC Group Object IOPCItemMgt IOPCGroupStateMgt IOPCSyncIO Note According to OPC DA version 2 conventions IOPCBrowseServerAddressSpace is optional, so GateOPC can run even if the OPC server does not have this interface. However, the OPC server item browse function is not available without this interface.
3.2 Detailed Description of Functions 1 Browsing OPC Server Items This function not available if the IOPCBrowseServerAddressSpace interface is not installed on the OPC server. You can search through all items on the OPC servers and display them in a format similar to the Windows explorer.

3.2 Detailed Description of Functions Adding Items to Groups You can add an item to a group. GateOPC limits the number of characters to 32. However, fewer than 32 may be allowed depending on the OPC server. Note These settings correspond to the OPC server settings and define GateOPC acquisition items. An item may not be able to be added depending on its type.
