I'm currently working on a project for a customer , Which uses Schneider HMIET6600x and Siemens plc Simatic S7-1200 . Overall the logic runs fine all the tags are added without any errors ,But when I start simulation a message pops up "plc returned error code" and some of the tags are not working properly ,after deleting and adding again works but errors keep increasing by one. I have attached images below.

Hi,
This error usually occurs when unsupported or non-existent addresses are defined in the screen configuration. It may also appear when working with data types such as Long Real (LREAL). To resolve the issue, you may need to add and test the variables step by step. Of course, if there are many variables, this can be quite difficult.
Since the Basic series does not support communication with data types like LREAL or LDINT without proper addressing, we typically recommend using the HMIST series when such data types are required.
I hope this information is helpful. Thank you, and have a great day.
