Upgrading a project from SoMachine HVAC to ESME HVAC

[POPE3909]

Hi Guys,

I'm trying to upgrade an old project written in SoMachine/FreeStudio (I'm using Eliwell version in this case) to the ESME HVAC/ Free Studio Plus by following this video tutorial.

I followed along all the steps exactly as shown but when I finally import and output into a new folder, the installer output has the following error:
"
Import procedure started
Parsing PLC project for target Carpark
Parsing slave resources and configuration
Parsing HMI remote project for target Carpark
SCRIPT ERROR! Descr: Invalid procedure call or argument, Err: 4, LineNum: 852, Code: (null)
Can not invoke function importOldCFNProject in extension importPrj: error 0x80020101 'Unknown error 0x80020101'
"

Could you please advise what could be the issue?

Thank you.

Hi,

be sure your Application project is saved as plcprj, if it is ppjs you have to save it as plcprj, relink it into Connection and User Interface and build all again.
