Hello. I have a multi-level structure in my data acquisition system where a standard parameter reads a register from the controller, and child logical parameters pull individual bits from this register. This is designed specifically to make it easy to copy similar blocks by changing the register address in just one place, rather than in each logical parameter. I'm encountering a problem where the connection to the source is broken when restarting the SCADA system. The configuration field specifies prm:../../word (+), but the connection is broken. What am I doing wrong?

You linked to a parameter "prm:../../word" where is no data attribute, and the relative links correctly work with wide using and testing!

Learn, learn and learn better than work, work and work.
