Description

When the reserved I/O module (set by the parameter) differs from the real loaded I/O module or a I/O module has been mounted or dismounted, the corresponding bit turns on.

Stores the system error code, (See Section 2.9)

Turning On/Off is repeated with a constant cycle.

On Off

Turning On/Off is repeated as many times as the scan specified by Duty instruction.

DUTY F010x N1 N2

N2 scan Off

N1 scan Off

Turns on when an operation error has occurred. Turns on when the operation result is “0”.

Turns on when a carry occurs due to the operation. Turns on when an output instruction is executed. Turns on when an operation error has occurred.(Latch) Turns on when overflow has occurred.

Turns on if S1 < S2 when using the CMP instruction. Turns on if S1 ≤ S2 when using the CMP instruction. Turns on if S1 = S2 when using the CMP instruction. Turns on if S1 > S2 when using the CMP instruction. Turns on if S1 ≥ S2 when using the CMP instruction. Turns on if S1 ≠ S2 when using the CMP instruction.

The error code generated by FALS instruction is stored to this flag.

Turn on when the current value of HSC reaches setting value Turn on when carry is occurred on the HSC current value
