ipmr223m-v1 and ipmr226 edge controllers include built-in Bluetooth Low Energy (BLE) provisioning. This allows electrical technicians to onboard new hardware units and configure network settings from a mobile tablet or smartphone without opening high-voltage electrical panels or plugging in serial debug cables.
Provisioning Workflow
Step-by-Step Commissioning Procedure
1. Power Up the Edge Node
- Ensure 3-phase or single-phase auxiliary control voltage is active.
- Verify the PWR LED illuminates solid Green.
- The WIFI LED will begin a rapid blue pulse, indicating the device is broadcasting its BLE configuration beacon.
2. Connect via Mobile Setup Utility
- Open the Industrial PMR Technician Setup Tool on your tablet or smartphone.
- The app automatically filters nearby devices by signal strength, presenting units within range (e.g.,
iPMR-PROV-A4CF12). - Select the unit matching the machine nameplate MAC address.
3. Select Wi-Fi Network & Enter Security Key
- The app queries the edge node to scan 2.4 GHz local Wi-Fi frequencies and displays discovered factory SSIDs with live signal strength ratings.
- Select the designated plant production Wi-Fi network.
- Enter the WPA2/WPA3 enterprise passphrase.
- Confirm the broker address (default:
mqtt.industrialpmr.com).
4. Verify Connection & Signal Strength (RSSI)
- The edge node attempts association with the plant access point.
- The technician app displays the assigned local IP address and live Received Signal Strength Indicator (RSSI):
Over-The-Air Security Lockdown
To prevent unauthorized tampering on the factory floor, the edge controller enforces strict radio isolation:- Automatic Radio Disable: Once the edge node establishes a successful Wi-Fi link and connects to
mqtt.industrialpmr.com, the onboard BLE radio shuts down completely. - Re-Provisioning Trigger: If network settings must be altered at a later date, a technician must hold the physical hardware setup button for 5 seconds to re-enable BLE advertising mode.
