IAC400 and IAC600 Digital Outputs Cannot Be Forced to Alternate Values in SBO/EBO

[Product_Support]

Issue

When importing IAC400 or IAC600 controllers into Building Operation via the Micronet Interface, digital outputs cannot be overridden or forced to a different value.

Product Line

EcoStruxure Building Operation, Satchwell MicroNet

Environment

• IAC400
• IAC600
• Building OperationServer

Cause

During the import process, the Digital Output Override State is incorrectly configured in the XML export file. Specifically, the <P1="IsNonVolatile"...> line contains a value that prevents the output from being overridden.

Resolution

⚠️ 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.

To enable digital output override functionality:

1. Create the SBO Export File in Visisat

   • Use Visisat to generate the XML configuration file for the controller.

2. Edit the XML File Before Importing into SBO

   • Open the XML file using a text editor such as Notepad++.
   • Locate the line containing:

     <P1="IsNonVolatile" Value="1" ...>​

   • Change the value from "1" to "0":

     <P1="IsNonVolatile" Value="0" ...>

3. Import the Modified XML File into SBO/EBO

   • Use the Data Import function in the MicroNet Interface to bring the corrected configuration into Building Operation.

4. Note

   • This issue does not affect IAC420 controllers.
