Instruction below is not connected to bus line:
6617 STL, RET, MCR, P, I, DI, EI, FOR, NEXT, SRET, IRET, FEND
or END
STL, MC or MCR can be used only in main program, but it is

used elsewhere (e.g. in interrupt routine or subroutine).
Invalid instruction is used in FOR-NEXT loop:

Contents of error Action
STOP the PLC, and correctly set the parameters.
• STOP the PLC, and correctly set the special parameters.
• Set special parameters correctly, turn OFF the power, and
then turn ON the power.
• Check the contents of the special parameter error code
(D8489), confirm troubleshooting for special adapters/
special blocks, and set special parameters correctly.
• Set special parameters correctly, turn OFF the power, and
then turn ON the power.
During programming, each instruction is checked. If a syntax
error is detected, modify the instruction correctly.
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.
Modify the instructions in the program mode so that their
mutual relationship becomes correct.
