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.
