To connect to SX_MDLW (OPC server), ProgID of the OPC server to be connected must be specified. ProgID of
SX_MDLW is shown below.
FUJI_ELECTRIC.micrex-sx.001
In addition, when accessing as remote, “NodeName” must be specified. As “NodeName,” set the computer name or TCP/IP
address.
5-3 Registering Groups
After connection to SX_MDLW has completed, register the group. There is information that can be registered to the server
at the same time with group registration. For details, refer to technical documents and specifications such as “Introduction
to OPC Applications” published by OPC Council Japan.
When connecting from SCADA software, group registration may be carried out internally and, in such a case, manual
registration of the group is not necessary. For details about connections, refer to sections related to OPC connections in
SCADA software manuals.
5-4 Registering Items
An OPC client registers an item to read/write the MICREX-SX system global variable. The name of the registered item is
specifically defined by the OPC server. An SX_MDLW item name has a hierarchical structure.
(project-path).(project-name).(configuration-name).(resource-name).(global-variable-worksheet-name).(global-variable-name)
As the project, configuration, resource and worksheet names, specify the names created by D300win. The variable name
in the global variable worksheet contained in them becomes the global variable.
Because SX_MDLW is compliant with OPC Data Access2.0, item names that can be accessed can be acquired using the
browse function.
