Question 1

Procedure to send commands over Modbus to PM5000 using Modbus Tester

Accepted Answer

Issue: Customer wants to send a command to a PM5000 to perform remote configuration or a meter reset. Product Line: PM5100 (PM5110) PM5300 (PM5330, PM5340) PM5500 (PM5560, PM5563) Environment: Remote meter configuration / resets Resolution: *Warning: The command procedure listed here can cause undesirable results to your product if applied incorrectly. Before sending any commands, verify all commands and parameters are correct. If you have any doubts, contact Technical Support for guidance.* The following instructions use a application Modbus tester to read and write the commands. Other Modbus polling software's can also be used. Step 1: Identify the Command Number and necessary Parameters Open the Modbus Register List of the concerned meter. These are mostly available in our websites under Software and Firmware sections inside firmware package files.Navigate to the Commands tab and locate the desired commandWrite down the Command Number and the Parameters In this example, the user wants to send the Reset All Energies command to the PM5560. As shown in Table 1, the Reset All Energies command number is 2020. This command also has 1 parameter, the command semaphore. This information will be necessary in Step 3. Step 2: Get the Semaphore In Modbus Tester, set the Data Type to "Holding Register (R03 / W16)".The Command Semaphore is stored in Modbus register 5680. Therefore, set the Starting Register to 5680.Set # or Registers to be 1.Then Click on Read once. Note: During this time no other communication with the meter should run in the background. Otherwise it may cause in error.Note: Only perform the reading operation once. Doing more than once will cause in error. If by mistake the operation is performed more than one time then it is advised to try to do the operation again after 4 min. Write down the Semaphore value Step 3: Sending the Command In Modbus Tester, set the Starting Register to 5000 and the # of Registers to 2. Note: If the command requires more than 2 parameters, increase the # of Registers accordingly. Modbus Tester only allows a maximum of 10 registers. If there are greater than 10 parameters for the given command, then a different Modbus polling software that is capable of writing more than 10 registers must be used. Set register 5000 to the Command valueSet register 5001 to the Semaphore valueSet registers 5002 - 5124 to the parameter values, if used For this example, recall that Reset All Energies has a Command value of 2020. Register 5000 = 2020 Register 5001 = 62283 Registers 5002 - 5124 = not used for this command Then Click "Write" Additional Information: What commands are available? A full list of the commands that can be sent to the PM5000 are detailed in the Modbus Register List under the Commands tab. The table below lists several of the most common commands: Warm Start ResetSet Date/TimeReset Cycle CountReset All Min/MaxReset All DemandsReset Power DemandReset All Peak DemandsReset Power Peak DemandsReset Input Metering Peak DemandReset All EnergiesReset All Accumulated EnergiesReset Input Metering AccumulationsMeter InitializationAcknowledge AlarmsDisable AlarmsClear Data LogReset Diagnostic Log What is a Semaphore and what is its purpose? The semaphore is a number that is used to control write access to the PM5000. The semaphore can only be read once in a 4 min by a single master. Therefore, it is the only master that can send a command within the 4 min period. This process guarantees that the PM5000 is only receiving a command from one device at a time. NOTE: The semaphore value which is received is valid for 4 minutes when not used, that is 4 minutes from the previous semaphore write. For example: if the received semaphore value is used at the 3rd minute 30th second from when the value is received, then the same semaphore is valid for next 4 minutes. You may use the semaphore value multiple times within that 4 minute window. You will need to read the command semaphore again after 4 minutes from the previous read has elapsed in order to get the new number.

Question 4

Can the Full PME Hierarchy Configuration be Exported/Imported

Accepted Answer

IssueOften times after creating a hierarchy within PME, it would be desirable to export and save the configuration outside of PME for backup purposesor for analysis in order to make further enhancements to the hierarchy.Product LinePower Monitoring Expert 7.xPower Monitoring Expert 8.xPower Monitoring Expert 9.0Power Monitoring Expert 2020Power Monitoring Expert 2021Power Monitoring Expert 2022Power Monitoring Expert 2023Power Monitoring Expert 2024 CauseThe Hierarchy Configuration Utility does have the capability to export a partial or skeleton hierarchy configuration to Microsoft Excel. The intent of this was to aid and expedite the creation of a hierarchy by extracting and associating devices to nodes within this skeletonconfiguration CSV file and importing the entries back into the Hierarchy Manager using the modified CSV file. This partial or skeleton hierarchyCSV file does not contain the full hierarchy configuration.ResolutionA new feature added in PME 8, allows the export of the full hierarchy configuration to an XML file. This can be done with the Hierarchy Configuration Utility. TheXML file can be viewed with an XML editor or a text editor such as Notepad++. It is also possible to restore a entire hierarchy from a previously exported XML file.Instructions for both exporting and importing to the XML are found in the section "Saving and Restoring a Hierarchy Configuration" beginning on page 22 of the"Hierarchy Configuration Guide" (attached). NOTE: Restoring a configuration XML file deletes the current hierarchy configuration and replaces it with the one represented in the file. For PME 7.2.2 and older, the Hierarchy Configuration Utility does not support Hierarchy configuration export in XML format Recommendation:If you are using an older version of PME, consider upgrading to the latest version for improved performance, protocol support, and security enhancements.For assistance with integration or upgrades, contact: pmo.support@se.com

Question 5

PM1000, PM1200, and EM6400 block registers

Accepted Answer

Certain registers must be read as a "block" from the PM1000, PM1200, and EM6400 meters. In order to read these registers, one must set the starting register to 3001, then 20 registers must be read in a single read. Attempting to read these registers in any other manner will result in either a time out or an error.The example in the picture below shows an scenario.Note: "Function Code: O3H Read" is stating that these registers are Holding Registers.The PowerLogic PM1000 Series Power Meters User Manual can be found here. It includes the PM1000/PM1200/EM6400 register list.

Question 9

What is the selection criterion of Circuit Breakers for the Capacitor bank application.

Accepted Answer

The selection should be done after derating the Circuit Breaker taking into consideration voltage variation and capacitors tolerances that could increase nominal current up to 1.5In. The Derating factor of 1.5In Where In = Q/ ( Square root of 3 ) Un Q = Capacitor Power Un = Nominal Voltage Choose the Micrologic with delay time selection, so that the Circuit Breaker does not trip due to initial high inrush current. Also to be taken into account are the parameters like supply frequency, operating voltage & harmonics level of the power system for such application. Refer the attached sheet for further details for selection of Circuit Breaker for Capacitor duty application. Note: Use the phase barrier between the phases in Circuit Breaker to prevent flashover due to heavy inrush current.

Question 10

Why is Neutral and Earth (Ground) Connection forbidden Downstream from Main Panel?

Accepted Answer

The question is often asked what is the maximum voltage permitted between the Neutral and Earth (Ground) conductor and if the Neutral and Earth can be bridged to achieve a zero value.This can be a difficult topic, in fact in many cases it can be dangerous. As you will see from the attached document, there are many reasons why it is not allowed.
