PowerMonitor 500 Unit Overview

Chapter 1

About the PowerMonitor 500 Unit

The PowerMonitor™ 500 unit is an AC power monitor with a built-in advanced configuration system and LCD data display. The unit is designed for measurement of electrical parameters in various three-phase, single-phase (2-wire European), and split-phase (3-wire North American single phase) circuits. The unit modular housing can be mounted in a panel that provides IP65 degree protection from the front. The power monitor can be provided with analog or digital (relay) outputs. These outputs can be selected to output a pulse proportional to the real and reactive energy that is measured, or to annunciate alarms. The instrument can also be equipped with a serial RS-485/RS-232 port or an EtherNet/IP port.

Equipped with an optional communication port, the unit communicates power and energy parameters to applications, such as FactoryTalk® EnergyMetrix™ software. The power monitor works with these software applications to address these key customer applications:

• Load profiling - log power parameters such as real energy, apparent power, and demand, for analysis of power usage by loads over time

• Cost allocation - report actual energy cost by department or process to integrate energy information into management decisions

• Billing and sub billing - charge users of energy the actual usage cost rather than allocating by square footage or other arbitrary methods

• Power system monitoring and control - display and control power flow and energy utilization

These diagrams are simplified. Wiring of the power monitor must comply with all applicable codes, standards, and regulations. Protect voltage and control power wiring with suitable overcurrent protection. Connect current transformer (CT) secondary wiring through a suitable shorting terminal block.

In these diagrams, ‘balanced load’ configurations permit 3-phase measurement by using only one phase connection. Unbalance in the measured circuit affects the accuracy of the measurements.

Chapter 3 Unit Configuration

Digital Filtering Operation

Digital filtering smooths out the display of fluctuating values. The parameter FILTER S defines the operating range of the filter. This operating range is represented as a yellow band (each small square is one digit). While the measured value (red curve in Figure 23 value exceeds the operating range, the filter is deactivated and a new band is active around the new value. The range of fluctuation (in digits) is a good starting value for such parameters.

The parameter FILTER CO represents the filtering coefficient. The higher the FILTER CO, the smoother the curve of the displayed values (black in Figure 23 There is not a theoretical rule to define this parameter, it is set in the field. One rule is to start with the value of the FILTER S coefficient and then increase FILTER CO until the desired stability is reached.

The digital filter affects the values retransmitted both via serial communication and analog output.

Digital Fluctuation

Digital Filter Programming Examples

This section gives digital filter programming examples.

Example 1

This example describes how to stabilize the displayed value of the VL-N variable, which fluctuates between 222V and 228V. The parameters of the digital filter have to be programmed as follows.

FILTER S: The variable fluctuates within the mean value whose amplitude is equal to ±0.75% of the full scale rated value of the variable itself, which is obtained by the following calculation:

(228 - 222)/ 2= ±3V, then ±3*100/400V= ±0.75% where 400V is the line-to-neutral rated value of a 1420-V2 unit input

32 Rockwell Automation Publication 1420-UM001E-EN-P - March 2016

Unit Configuration Chapter 3

The FILTER S parameter, which represents the action range of the digital filter, is programmed to a value that must be slightly higher than the percentage amplitude of the fluctuation, for example, 1.0%.

FILTER CO: if the new value that is measured by the instrument is within the action range of the filter, the new displayed value is obtained by adding algebraically the previous value to the variation divided by the filtering coefficient. As a consequence, a value higher than this coefficient implies a longer settling time and therefore better stability. You generally obtain the best result by setting the filtering coefficient to a value equal to at least 10 times the range parameter value.

In the following example, 1.0*10=10, the stability of the filtering coefficient can be improved by increasing the filtering coefficient; the allowed values are included within 1 and 255.

Example 2

This example describes how to stabilize the value of the displayed System Real Power (W), which fluctuates 300...320 kW. In this example, the load is connected to the instrument with a 300/5 A CT and a direct measure of the voltage.

The parameters of the digital filter must be programmed as follows.

FILTER S: the variable fluctuates within the mean value whose amplitude is equal to ±2.78% of the full scale rated value of this variable. This value is obtained by the following calculation:

(320 - 300)/ 2= ±10 kW, then ±10*100/360 kW= ±2.78%,

where 360 kW is the rated value of the System Real Power of a 1420-V2 unit input, at the CT and VT ratios and obtained with the following formula:

VLN * VT * IN * CT * 3

Where:

VLN = rated input voltage (400V for the V1 input)

VT= primary/secondary ratio of the voltage transformer being used

IN = rated current (5 A)

CT = primary/secondary ratio of the voltage transformer being used (in this example 400*1*5*60*3=360 kW).

The FILTER S parameter, which represents the digital filtering coefficient action range, is programmed to a value that must be slightly higher than the percentage of the fluctuation: for example 3.0%.

Rockwell Automation Publication 1420-UM001E-EN-P - March 2016 33

Chapter 3 Unit Configuration

FILTER CO: if the new value that is acquired by the unit is within the filtering action range, the new displayed value is obtained by adding algebraically the previous value to the variation divided by the filtering coefficient. As a consequence, a value higher than this coefficient implies a higher settling time and therefore better stability. Therefore, the best result is obtained by setting the filtering coefficient to a value equal to at least 10 times the value of the range parameters. In the example, 3.0*10=30. To improve the stability, you can increase the filtering coefficient; the admitted values are included within 1 and 255.

Example 3

It is necessary to stabilize the value of the displayed variable A L1 (phase current 1), which fluctuates in the range 470 A and 486 A.

To be able to manage the alarm function and activation and deactivation of the relay, this value is not to be subject to continuous fluctuations. In this example, we have considered using a 500/5 A CT. Program the parameters of the digital filter as follows:

FILTER S: the variable fluctuates within the mean value whose amplitude is equal to ±1.60% of the full scale rated value of this variable (obtained with the calculation:

(486 - 470)/ 2= ±8 A, then ±8*100/500 A= ±1.60% where 500 A is the value referred to the primary of the transformer being used).

The FILTER S parameter, which represents the action range of the digital filter, is programmed to a value slightly higher than the percentage amplitude of the fluctuation, for example 2.0%.

FILTER CO: if the new value that is acquired by the instrument is within the filtering action range, the new displayed value is calculated algebraically adding to the previous value the variation divided by the filtering coefficient. As a consequence, a higher value of this coefficient implies a higher settling time and therefore better stability. Therefore, the best result is obtained setting the filtering coefficient at a value equal to at least 10 times the value of the range parameter. In the example, 2.0*10=20. To improve the stability, you can increase the filtering coefficient; the admitted values are within 1 and 255.

Analog Output Configuration Examples

These examples apply to units with catalog numbers 1420-V1A and 1420-V2A.

Example 1: Power value retransmission with a 0…20 mA analog output.

This example describes how to retransmit measured power up to 100 kW with a 4…20 mA signal. Program the unit as follows:

• VAR IA BL E: W

• MIN OUT: 20.0% means 4 mA. The calculation that is used is the

following: (100*minimum output) / full scale output =100*4 mA/ 20 mA=20%

• MAX OUT: 100.0% means 20 mA. The calculation is the following: (100*maximum output)/full scale output = 100*20 mA/20 mA= 100

• MIN INPUT: 0.0 k; the multiplier k, M, G can be selected on the unit according to the chosen VT and CT values

• MAX INPUT: 100.0 k; the k, M, G multipliers can be selected on the unit according to the selected VT and CT values

Example 2: Retransmission of the power factor (PF) value with the 0…20 mA analog output.

In this example, the unit is configured to retransmit the whole range of the allowed values for the PF with a signal from 0…20 mA. The value of the PF variable can vary between C0.001 and L0.000 (for each phase); these values, when retransmitted, correspond to 0 mA and 20 mA. When the PF value is equal to 1, the analog output value corresponds to the middle of the scale, which is 10 mA. Program the instrument as follows:

• VARIABLE: PF L1 (or L2 or L3 or PF

• MIN OUT: 0.0%

• MAX OUT: 100.0%

• MIN INPUT: C0.001 (the C symbol shows a CAPACITIVE value)

• MAX INPUT: L0.001 (the L symbol shows an INDUCTIVE value).

L0.001 has been chosen as minimum value to be set to avoid undesirable rapid changes of the outputs

5. When finished, click OK to save the new module.

The module updates its input tag <Name>.I.Data at the Requested Packet Interval (RPI).

You can use additional programming to show the data in another way. Instances 101…107 show data in the REAL, or floating point, format. However, Instance 100 combines ASCII characters with numeric byte (SINT) values.

This program displays the contents of Instance 100 in a more human-readable fashion:

• The XIC instruction on tag ‘bool_Convert_i100’ enables the conversion.

• The first CPS instruction copies the first 6 bytes of the module input data

tag.

• The MOV instruction sets the serial number string length to 13.

• The last CPS instruction copies the serial number from the module input

data tag that starts at element (byte) 6.

IMPORTANT

The destinations of the CPS instructions are in a tag with a user-defined data type.

The destination tag shows the data in this way.

Modbus Communication

For a complete description of the MODBUS protocol refer to the following documents that can be downloaded from http://www.modbus.org

• Modbus_Application_Protocol_ V1_1a

• Modbus_Messaging_Implementation_Guide_V1_0a

Modbus Functions Supported

Modbus RTU is supported in PowerMonitor 500 units that are ordered with optional RS-485/RS-232 communication. In addition, Modbus TCP/IP is supported in units that are ordered with optional Ethernet communication. Communication parameters in the power monitor must be configured. See the

Unit Configuration

section of this manual.

We recommend that you use Modbus TCP/IP to configure or write to the PowerMonitor 500 unit and that you use Ethernet/IP to read the PowerMonitor 500 unit.

Rockwell Automation Publication 1420-UM001E-EN-P - March 2016 43

Chapter 4 Communication

The PowerMonitor 500 unit supports the following Modbus functions:

• 0x03 - Read n Holding Registers

• 0x04 - Read n Input Register

• 0x06 - Write one Holding Register

• 0x10 - Write multiple registers

• 0x08 - Diagnostic (with subfunction code 0x00)

• 0x42 - Read n Special Registers (vendor specific)

• Broadcast mode (write command on address 00h)

In this section, Modbus addresses are indicated in two ways. The ‘Modbus address’ is expressed as the 6-digit input register address (example: 300123), used with Modbus function code 0x04. The ‘Physical address’ is the hexadecimal representation of the word address that is included in the communication frame.

Modbus function 0x04 can be used with the Modbus address by substituting a 4 for the first digit (example: 400123). With that distinction, functions 0x03 and 0x04 return the same data.

To avoid errors due to signal reflections or line coupling, a termination resistor must be connected at the RS-485 ports of the master station and of the furthest power monitor from the master station. In the PowerMonitor 500, you can implement a jumper between (B+) and (T) to apply the required termination resistance between (A-) and (B+) internally. Termination on both ends is necessary even in case of point-to-point connection, with short distances.

The GND connection is optional if a shielded cable is used. For connections longer than 1000 m (3280 ft), a line amplifier is necessary.

PowerMonitor 500 EtherNet/IP Device Profile

This section describes the specific CIP Objects, Instances, Attributes, and Services that are supported by the PowerMonitor™ 500 system. This information is for anyone wishing to integrate the PowerMonitor 500 system into existing or planned shop floor networks.

General

Object Model and Interface

Identity Object - CLASS CODE 0x0001

For this device profile, we use a PowerMonitor 500 unit and an EtherNet/IP communication module to provide power and energy metering data via an EtherNet/IP network. The data is accessed as instances of the device Assembly Object.

This profile documents objects that are proprietary, or in some way that is altered from their generic behavior. Standard CIP objects that are generic in their interface are documented in the EtherNet/IP specification.

The PowerMonitor 500 system is represented by the following Object Model.

Object Class Class Code Instance Numbers Number of Connections

Identity 0x0001 1 0

Assembly 0x0004 100d…108d 18

The Identity Object is used to provide identification information about the device. Each node supports at least one instance of the identity object. The Identity Object is used by applications to determine which nodes are on the network. The Identity Object supports Class Attributes (Instance 0) and Instance 1.

See Section 5-2 of the CIP Common Specification for full details of this object.

PowerMonitor 500 EtherNet/IP Device Profile Appendix C

Connections

The Assembly Object supports both scheduled (Class 1) and unscheduled connections (Class 3 and UCMM). Both connections are used to access instances 100d to 108d of the Assembly Object:

• UDP - Nine Class 1 connections each to the nine Assembly Instances 100 to 108 at 100 ms RPI ran stable

• TCP - Nine Class 3 connections each to the nine Assembly Instances 100 to 108 at 200 ms RPI ran stable

• Both - UDP and TCP can run simultaneously

Heartbeat Instances

With the Assembly Instances shown earlier, the communication module also recognizes two heartbeat instances. A heartbeat instance is a virtual output instance that is specified by devices wishing to establish Input Only and Listen Only Class 1 I/O connections to the communication module. Data cannot be read from or written to a heartbeat instance. The heartbeat instance is merely a programming construct that serves to keep the connection active.

Technical Notes

The communication module heartbeat instances are Instance 98 for the Input Only connection and Instance 99 for the Listen Only connection.

Behavior

The purpose of the Assembly Object is to act as a network interface to the PowerMonitor 500 unit data. That data is accessed by various means: Class 1 or Class 3 connections and also with UCMM messages.

This section lists additional technical information about Ethernet network communication.

Parameters

For the EtherNet/IP communication module, set the following parameters by using Programming mode through the base module front panel:

• IP address

• Subnet

• Gateway

• Modbus TCP/IP port

• Address Conflict Detect (ACD)

Rockwell Automation Publication 1420-UM001E-EN-P - March 2016 83

Appendix C PowerMonitor 500 EtherNet/IP Device Profile

IMPORTANT

Modbus TCP/IP

The communication module supports Modbus TCP/IP. The protocol is the same as the PowerMonitor 500 unit with RS-485 (Modbus RTU). See Chapter 4 for protocol details. In this product, only one Modbus TCP/IP connection (one socket) is allowed.

The EtherNet/IP and Modbus TCP/IP do not run concurrently. If ModbusTCP/IP communication occurs, EtherNet/IP communication stops temporarily but recovers in a minute or two.

We recommend that you use Modbus TCP/IP to configure or write to the PowerMonitor 500 unit and that you use Ethernet/IP to read the PowerMonitor 500 unit.

ACD

If an address conflict is detected from the communication module, then the base module displays ‘ACD Found’. In that case, it is necessary to check the network configuration, resolve the problem, and then cycle control power to the power monitor to re-establish communication.

TCP/IP Port

Default EtherNet/IP ports include the following:

• UDP (implicit message): 2222 (0x08AE)

• TCP (explicit message): 44818 (0xAF12)

You can reassign the default Modbus TCP/IP port: 502 (0x01F6).
