Issue
IAC touch screens unexpectedly reset to their default address (65) every Sunday when time broadcast is enabled.
Product Line
EcoStruxure Building Operation, Satchwell MicroNet
Environment
- Building Operation Enterprise Server
- Building Operation Automation Server
- MicroNet transition
- IAC touch screen
Cause
When the AS or ES broadcasts time to MicroNet devices, the day number is incorrectly sent as 0 on Sundays instead of 7.
The IAC touch screen does not recognize day 0, which triggers a reset to factory defaults, including its network address.
Impact:
- The touch screen resets to address 65.
- If the original address was not 65, communication with controllers on the SubLAN fails.
- Manual reconfiguration is required to restore connectivity.
Resolution
The issue is resolved in SBO version 1.8 and later.
⚠️ Important Notice
Satchwell MicroNet is not supported in EBO 2022 and later.
To continue supporting MicroNet devices, you can implement a multi-version system:
- Keep Servers with MicroNet devices on Building Operation 3.2.
- Upgrade the rest of the system to Building Operation 2022 or later.
You will not be able to upgrade EcoStruxure Building Operation servers that contain unsupported protocols, objects, or devices. Attempting to do so will result in failed upgrades or loss of functionality.
