1 Task

Introduction

The real-time visualization of energy data from the field level is a more and more frequent requirement for an industrial control system.

It allows, for example, for viewing and monitoring the voltages, currents, and other energy-specific key figures of a consumer or plant part.

In order to prevent additional engineering effort in the automation system (PLC), the power meter is directly connected with the control system.

Overview of the automation task

The figure below provides an overview of the automation task.

Figure 1-1

Description of the automation task

The direct connection of the power meter allows direct visualization in the control station and – on request – also permanent archiving.

General overview

Figure 3-1

As can be seen in Figure 3-1, the application consists of two major software components.

One component represents the faceplate that visualizes the Sentron PC power meter within WinCC Runtime.

The second component is an "HMI data type" that defines the structure of all available measured values. Direct access to the values of the power meter is effected by specifying the "offset value".

These two components can be used in your own project without any additional configuration effort.

The connection between WinCC Runtime and the power meter is established via an Ethernet connection and the communication driver "Modicon Modbus TCP/IP".

3.1 "HMI data type" functionality

Figure 3-2

With an "HMI data type" a data structure can be pre-configured. From this structure can then instance tags be created that directly refer to a data area in the automation system (PLC) or other external devices.

The HMI data type "Sentron PAC" contains by default all measured values listed in section 2.2.

Note It is irrelevant whether the faceplate for Sentron PAC3200 or Sentron PAC4200 is used. Both faceplates visualize the same measured values by default.

If required, the HMI data type can also be adapted to your requirements. Further information on the creation and operation of these data types can be found in the help on WinCC Professional V11 at the following link: http://support.automation.siemens.com/WW/view/en/57341024

The data type contains 91 tags by default. These are 90 external tags representing the values from the power meter and one internal tag representing the "PAC_Index" value.

Figure 3-3

The faceplate provided by this application consists of several single screens.

Figure 3-4

For each measured value read out of the power meter there is one process screen. Example: „PAC3200_Voltage_PH_N“ for the voltage between phase and neutral conductor. In the respective process screen, the output fields for instantaneous, maximum, and minimum values are distributed to the three levels "INST", "MAX", and "MIN".

Figure 3-5

The screens with the measured values are displayed at runtime in the "PAC3200_Main" process screen using the screen window technology.

In this process screen, not only the graphical interface of the faceplate is defined but also the order in which the screens are displayed at runtime when the operator clicks the "F2" and "F3" buttons.

The order is defined in a list box that can be shown or hidden via level 6 "Engineering".

By default, the screens are called in the order which the operator knows from the power meter.

Figure 3-6

Note The screen names in the list box must be identical with the actual screen names in the project tree.

Since there are no minimal values for the measured values "THD-R V" and "THD-R I", a field with the inscription "INST" is configured on level 7 "Special", which is displayed only when the user has the maximum values of these measured values displayed at runtime.

Program details on the visibility of the INST, MAX, and MIN values

Depending on an internal counter tag "PAC_Index", the INST, MAX, and MIN values of the respective measured value are displayed.

2 Maximum values (MAX)

3 Minimum values (MIN)

Also depending on the value of the "PAC_Index" tag, the objects on level 4 "Display 2" and level 5 "Display 3" are shown or hidden.

The "PAC_Index" tag is also contained in the HMI data type and must be created for each visualized power meter.
