(Note-1) : Handling of D704 to D708 and D755 to D757 register
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 "5 MOTION DEDICATED
PLC INSTRUCTION " for S(P).DDRD and S(P).DDWR instruction.
(Note-2) : Device area of 9 axes or more is unusable in the Q172CPU(N).
(Note-3) : The range of axis No.1 to 8 is valid in the Q172CPU(N).
(Note-4) : It can also be ordered the device of a remark column.
(Note-5) : M3080 does not turn off automatically. Turn it off as an user side.
(Note-6) : It is unusable in the SV22 real mode.
CAUTION
The data executed later becomes effective when the same device is executed simultaneously
in the Motion SFC and PLC program.
