With such a convention, a data point called CEDAR_220_BUS_V_phsA_mag clearly
indicates the voltage magnitude of phase A on the 220 kV bus of the CEDAR substation. A data
point called MAPLE_025_F1_Pos_st indicates the status of the breaker switch of feeder 1 at
the MAPLE substation.
Still in the General settings, enter the scanning settings.
For instance, to configure a MODBUS master protocol, you would provide settings such as
the following:
A Device Address, typically 1.
A MODBUS Type, typically RTU Serial.
A Scan Interval, typically 1000 ms.
A complete description of all settings is provided in the document entitled Master Protocol
Common Concepts. Protocol-specific settings are described in individual documents, such as
DNP3 Master Protocol.
5.1.3.1 Accessing Protocol-Specific Documentation
There are Cooper Power Systems documents available, to which you can refer for details on the
settings of the currently supported protocols.
To access the documents, proceed as follows:
Click Start, on the Windows taskbar.
Point to All Programs, then Cybectec, then SMP Tools, and then Documentation.
In the Documentation menu, click Protocols.
The list of available documents is displayed in an explorer window.
Click the document you want to read.
In the File menu of the explorer window, click Open with Acrobat.
Your Adobe Acrobat program starts up and displays the document in a window.
5.2 Configuring the Data Points
Once you have provided the general settings of the protocol component, you then enter all the data
points on the device. If you created the protocol instance from a template, all the data points have
already been added; however, we suggest you read this section for your information.
Protocol components typically support physical and logical data points of the following types:
Analog inputs
Binary inputs
