No error
6610
Stops
operation
LD, LDI is continuously used 9 times or more.
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.
6611
More ANB/ORB instructions than LD/LDI
instructions
6612
Less ANB/ORB instructions than LD/LDI
instructions
6613 MPS is continuously used 12 times or more.
6614 No MPS instruction
6615 No MPP instruction
6616
No coil between MPS, MRD and MPP, or incorrect
combination
6617
Instruction below is not connected to bus line:
STL, RET, MCR, P, I, DI, EI, FOR, NEXT, SRET,
IRET, FEND or END
6618
