Description
The meaning of the attribute "length" of an IO signal was changed.
Up to SYCON.net <= V1.400 "lenght" was used for the length definition of the data type string. for all other data types the value was set to 0.
Starting with SYCON.net >= 1.500 "lenght" describes the number of array elements of a data type.
An array index with the value 0 means that no IO information is generated in the database and address table. This results in a incnsistent datamodel.
Solution is to change the data length to the default value of 1 in case of loading an old project with data length = 0.
