Device Information Serial number not showing

[Bryanbyte]

Hi,

I would like to ask for assistance regarding device identification in ION Setup.

I am currently scanning multiple Schneider PM2200 series power meters (specifically PM2230) via Modbus in ION Setup. All devices are successfully detected, and communication is confirmed (I can read measurement data without issue).

However, I noticed that for some meters, the Device Information (e.g., serial number) is not displayed during the scan, while other meters of the same model do show complete information.

Details:

• Same model: PM2230
• Communication: Modbus RTU (working)
• ION Setup device type: correctly selected based on field device
• Using Modscan, I can manually read the serial number (e.g., register 130) from the affected meters
• Firmware example: OS Firmware 1.4.0, RS Firmware 1.0.1

Based on testing, it seems the serial number exists but is not being interpreted/displayed correctly in ION Setup.

My questions:

1. Are there known differences in firmware or Modbus register formatting (e.g., word/byte order) that affect how ION Setup reads device identity?
2. Does ION Setup rely on a fixed device profile that may not match certain firmware versions?
3. Is there a recommended way to ensure full device information (serial number) is displayed consistently across all meters?

Any guidance or clarification would be greatly appreciated.

Thank you.

Hi @Bryanbyte Please share some more details like ION setup version you've used, affected meter's S/N & FW version as well as some unaffected meter's S/N & FW version.

Here is one of the Meters I have in my shelf I encounter having same issue. I have installed another 10 at the site but I can't give its SN.

Hello @Bryanbyte With the meters in our lab, we are not getting such issues. Please try upgrading the ION setup version and see if it helps.

Hi @Robert_Lee Please check and answer for this query.

Yes, that ION Setup is 4.5 years old (late 2021 based on that build #).

I would also confirm using the integrated Modbus Tester UI in ION Setup (click on the Troubleshooting tab you see in your screenshot) and use the Modbus Ident (0x2B) and Read Holding Registers (0x03) to confirm the SN# register is being read correctly.
