(Note-1): The range of axis No.1 to 8 is valid in the Q172HCPU.

(Note-2): Device area of 9 axes or more is unusable in the Q172HCPU.

(Note-3): This signal is unusable in the SV13/SV22 real mode.

(Note-4): Handling of D704 to D708 and D755 to D757 registers

Because cannot be turn ON/OFF for every bit from the PLC CPU, the above bit devices are assigned to D register, and each bit device becomes on with the lowest rank bit 0 1 of each register, and each bit device becomes off with 1 0.

Use it when the above functions are requested from the PLC CPU using the S(P).DDRD and S(P).DDWR instruction. Refer to the "Q173HCPU/Q172HCPU Motion controller (SV13/SV22) Programming Manual (Motion SFC)" for the S(P).DDRD and S(P).DDWR instruction. The direct bit device ON/OFF is possible in the Motion SFC program.

(Note-5): It can also be ordered the device of a remark column.

(Note-6): M3080 does not turn off automatically. Turn it off as an user side.

CAUTION

The data executed later becomes effective when the same device is executed in the Motion SFC program and PLC program.
