Getting error: Cannot complete startup ... Exception was thrown: DataLinkDAL Execute Exception: Index and length must refer to a location within the string. Parameter name: length

The most likely cause of this error is that one or more items located in a group under <ProjectName> has either an item name or value that exceeds the character limit permitted by the data storage.

For example: An item name length could be 200 characters and exceed a databases 150 character limit for the particular cell.

This error can also occur if the user is attempting to log an array. The Data Logger does not support arrays at this time.


To resolve, check the length of the itemname under the group and verify the length allowed to the column that the data is logging too. Please also know that any attribute you may be logging length will need to be verified.
