Action
Each instruction is checked during programming.
If a syntax error occurs, correct the improper instruction in the
program mode.
This error occurs when a combination of instructions is incorrect in
the entire circuit block or when the relationship between a pair of
instructions is incorrect.
Correct the instructions in the program mode so that their mutual
relationship becomes correct.
