If, for example, you use a multiplex tag in a script, after changing the memory area you do not directly access its content. => In a script, avoid changing the index of multiplex tags and then accessing those tags. Changing the index of multiplex tags and then accessing those tags (e.g. within the same script) can cause data inconsistency! Actully I have 200 words in a DB that I need change all together (Temperature Set point) so do you have any suggestion on how to do it?
