text: <s>[INST] Transaction Manager V13.10 String data issue. last week FTTM V13.10 installed and tested with 1756-L71  PLC V24. I am able to write data from PLC to SQL table. I am trying to read data from SQL table using stored procedures method. Compare string from PLC tag with SQL table. When configure string instead of PLC's tag, able to read data from SQL to PLC. When i use PLC string tag, no data. [/INST] Regarding the PLC string tag no data reading from SQL via FTTM transaction, it should be caused  by that the .LEN field of string tag does not automatically get updated while writing the CLX STRING data type via FTTM. To workaround this shortcoming, either Define an additional data item in FTTM for the string_tag.LEN field, and output the length value from the database stored procedure as well, or Program additional ladder logic to update the string_tag.LEN field when the .DATA is written. Hope it will be working for you. By the way, it seems your account has not RA TechConnect entitlement.
