Read Only Mode- Online editing not available when IEC enabled on Momentum Wages A8

Issue
Read Only Mode- Online editing not available when IEC enabled error  when changing the modbus serial id.

Product Line
Momentum Wages Devices

Environment
Using PortCon to change the modbus serial id

Cause
IEC upload information was not checked in Concept when the project was uploaded or was loaded with Concept 2.5 or lower. 

Resolution
The original project needs to be reuploaded to the device. Reloading the project is the only way to do this since the project was uploaded locked. 
The  procedure to upload the original project can be performed using the DEVCON user guide in FA221550  on page 12
On page 13 before starting Procedure 2, Go to Project -> Code Generation Options -> Check Include IEC upload information. This will allow the communications information to be changed in the future on the device. 
Continue the process to the end of Chapter 5 on page 22.
