PLCnext Engineer 2021.0 Compile Errors

robhuisken · December 16, 2020, 12:33pm

I am working on moving from 2020.6.2 to 2021.0. I have two different projects, both for AXC F 2152 FW2020.6, utilizing many of the same libraries and functions but I get different errors with each of them:

                                             * Project 1: Several instances of: SEM1275: The value '49680' exceeds the range '-32768..32767' of data type 'INT'
                                             * Project 2: Single instance of: UTL0001: Internal error.

Any guesses as to what the issue could be? Thanks, Rob H

Project 1: Several instances of: SEM1275: The value ‘49680’ exceeds the range ‘-32768..32767’ of data type ‘INT’

                                               * Haven't found issue, yet
                                             * Project 2: Single instance of: UTL0001: Internal error. 
                                               * Found the issue to be caused by a symbol list on the HMI that used a symbol with a symbol inside it. Nested symbols inside a symbol list are apparently a no go.

Hello Rob,

thank you for sharing this.
Can we contact you via mail for an example of the Symbol that is not working in your case?

Please try using a UINT instead.
The error is caused by a new compile time protection mechanism.
This just helps avoid range index errors.

kind regards,
Oliver

Hi Oliver, I have been looking over the change notes - there is not mentioned the new compile time protection mechanism and that this could give us issues. Would have been nice to know. Peter Paul

Hi I think I got the same problem on my PLCnext 1152 project. Can you show me how to solve this problem? And will I got this problem everytime I want to upgrade the software? Errormessage: SEM1275 The value ‘49153’ exceeds the range ‘-32676..32767’ of data type ‘INT’

Hi pudderjagar, As Oliver mentioned, there is a relatively new compile time protection mechanism that can generate this error. Please try declaring the problem variables as UINT instead of INT. [quote]will I got this problem everytime I want to upgrade the software?[/quote]No, once the problem is fixed in the project, this error will not appear again for the same project in future versions of PLCnext Engineer.

Hi I’ve tried several times to swoop from INT to UINT. The problem is that Im using several librarys and I dont know how to edit the librarys. Can you tell me how to do it or where I can find a updated version of them? I’ve tried the PLCnextStore but they seems to be deleted from here. Maybe I can use someone else? Im using this librarys: IP_Com_9 IT-Library_9 Modbus_TCP-8 PLCnextBase_1_1_0 Solartracker

Martin_PLCnext_Techn · November 30, 2021, 1:00pm

The following libraries are still available in the PLCnext Store, so you can get the latest versions there: [list] [] IT-Library [] Modbus_TCP [*] PLCnextBase [/list] The IP_Com library is no longer available on its own in the PLCnext Store, but it is bundled with the IT_Library. The Solartracker library was never available in the PLCnext Store. I will email this to you separately.

Hello, I am facing the same issue without any external libraries. The internal error appears randomly, and refuses to disappear even when all resources are removed from project. To the extent that the error is active even though only Project object remains in Plant explorer. I am using 2021.9 Build 4.12.200.0.
