Register 40101 kWh
Register 40102 MWh
Product
Power Monitoring Expert 7.2.2
Power Monitoring Expert 8.2
Power Monitoring Expert 9.0
Power Monitoring Expert 2020
Power Monitoring Expert 2021
Power Monitoring Expert 2022
Power Monitoring Expert 2023
Power Monitoring Expert 2024
Environment
Modbus Device Importer (MDI)
Device Type Editor (DTE)
Cause
DTE does not natively support register type MOD 1K, MOD 10K is a supported register type
Resolution
*Warning: Take backups of any files prior to modifying them. Ensure the backups are in a location that will not be overwritten (i.e. the Desktop).*
Note that registers defined as offset will be updated with the slow speed update rate.
Solution includes a combination of scaling, multiplier and offset registers.
1) Create a new register linked to the lowest register, set the scaling to 1000 and multiplier to -1
- Recommend naming this register other than the desired final register name eg kWh Del 10E-3
2) Create a second register. Set the scaling to 1000, and multiplier to -1. Add an offset register created in step 1.
- Recommend naming this register other than the desired final register name- recommend eg. kWh Del 10E0
3) Create a third register. Set the offset register to the register created in step 2. Add a multiplier to give the correct desired units.
- Name this register the desired measurement name. eg kWh del.
This process can be repeated for more than 3 registers
Recommendation:
If you are using an older version of PME, consider upgrading to the latest version for improved protocol support and security. For assistance with integration or upgrades, contact Schneider Electric Technical Support at: pmo-psup@se.com
