ABCLX fails to come online depending on the structure of the tags in the PLC.

When ABCLX attempts to bring a PLC online, it downloads all the tags in the PLC before subscribing them. Details of how this is done are published in KB Q4001.

If you have a structure within a structure within a structure, etc in your PLC, it is possible that ABCLX will not be able to come online. This has previously been corrected by use of the multiserviceadjust parameter.

This parameter is now obsolete as ABCLX no longer has this problem.

Citect has confirmed this to be a problem in ABCLX versions to This problem has been fixed in version
