800xA Function designer generates Syntax error in XML
I have 800xA 5.1 installation with AC800M redundant controllers with some applications. One application contains function with sequence SFC2Header and Sequence2D blocks and another logic on 18 pages created in function designer (not by me). Everything was ok until I wanted to add one simple OR block into the logic. After that I cannot generate configuration data because there is an error generated: Syntax error in XML and CCB generates error: Fatal call of Error Handler... . I am out of any idea what could be wrong. Could it be due to the usage of SFC blocks inside the function? Do I have to edit such functions in different way? Thanks for your reply.
