The GE Series 90 TCP/IP Ethernet OPC Server communicates
with GE Series 90 PLC(s) via the SRTP protocol.
The SRTP protocol is utilized within TCP/IP packets over
an Ethernet network and is processed by the PLC via the
Processor module or the CMM 741 or CMM 742 Ethernet
Controller module. No GE Host Communication Software run-time
license is required for the Server.
Device redundancy is built into the server. It can be configured to provide
complete, automatic switch over to backup controllers on failure detection or
under application control. Device redundancy provides uninterrupted data
transfer between the process and the client application(s).
The GE Series 90 TCP/IP Ethernet OPC Server
supports data exchange with Clients via Microsoft's Object Linking and
Embedding (OLE) for Process Control (OPC). This Server meets the OPC Data
Server Specification Version 2.0. It also supports OPC Version 1.0.
The Server has a graphical user interface (GUI) configuration environment
with an "Explorer" look and feel. The configuration environment allows
the Server to be configured with information such as which device to interface
with and which data in those configured devices should be accessed. Once
data points have been configured, the Server can communicate with these
devices on behalf of the Clients. Data exchanged occurs between the Server
and the defined device data locations. These locations are defined
as part of the configuration process generating Tags in the Server database.
Clients and the Server then reference the data via the tag names.
The Server was developed by DASTEC Corporation using the OPC Server
Toolkit from FactorySoft, Inc.
