Are IEC 61131-3 languages ​​Turing complete?

Question

Theory

Are Instruction List, Structured Text, FBD, Ladder Diagram and SFC Turing Complete?
I did not find direct or indirect confirmation, but the absence of evidence is not a refutation
. UPD:
You are right, Snailmind .
SFC (Sequential Function Chart) is a graphical programming language in which a program is described as a schematic sequence of steps connected by transitions.
Thus, in fact, a finite state machine is created, the number of possible states of which is finite. The result of the automaton is determined by its final state. And the finite automaton is a Turing-incomplete formalism.

Answer 1

A Turing-complete language is one in which any computable task can be performed. I think most likely not. at least the Ladder Diagram is definitely not Turing complete.
