No error
6501
Stops
operation
Incorrect combination of instruction, device symbol and device
number
During programming, each instruction is checked. If a syntax
error is detected, modify the instruction correctly.
6502
No OUT T or OUT C before setting value
6503
No setting value after OUT T or OUT C
Insufficient number of operands for an applied instruction
6504
Same label number is used more than once.
Same interrupt input or high-speed counter input is used more
than once.
6505
Device number is out of allowed range.
6506
Invalid instruction
6507
Invalid label number [P]
6508
Invalid interrupt input [I]

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
STL, MC or MCR can be used only in main program, but it is
used elsewhere (e.g. in interrupt routine or subroutine).
6619
Invalid instruction is used in FOR-NEXT loop:
STL, RET, MC, MCR, I (interrupt pointer) or IRET.
6620
FOR-NEXT instruction nesting level exceeded
6621
Numbers of FOR and NEXT instructions do not match.
6622
No NEXT instruction
6623
No MC instruction
6624
No MCR instruction
6625
STL instruction is continuously used 9 times or more.
6626
Invalid instruction is programmed within STL-RET loop:
MC, MCR, I (interrupt pointer), SRET or IRET.
6627
No STL instruction
6628
Invalid instruction is used in main program:
I (interrupt pointer), SRET or IRET
6629
No P or I (interrupt pointer)
6630
No SRET or IRET instruction
STL-RET or MC-MCR instructions in subroutine
6631
SRET programmed in invalid location
6632
FEND programmed in invalid location
