Power Distribution, Inc. (PDI) M4 OPC Server

The Power Distribution, Inc. (PDI) M4 OPC Server reads and writes data from and to the M4 Power Monitoring System(s) using the M4 ASCII protocol. The M4 Power Monitoring System provides a RS-422 communication gateway for PDI’s Harmonic Cancellation Systems (HCS), Power Distrubution Units (PDU) and Static Switches. This Server meets the OPC Data Server Specification Version 2.0. It also supports OPC Version 1.0.

The Server allows the user to configure bi-directional communications between its database and the M4 systems. It can be configured to interface to one or more M4(s) on a single Rs-422 network or via multiple communication ports.

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.
