4 MOTION DEDICATED PLC INSTRUCTION
POINT
Access from the PLC CPU is processed before the communication processing of
the Motion CPU. Therefore, if the Motion dedicated PLC instruction is frequently
performed from the PLC CPU, the scan time of the PLC CPU is not only prolonged,
but delay will arise in the communication processing of the Motion CPU.
Perform execution of the Motion dedicated PLC instruction from the PLC CPU by
S(P).DDWR/S(P).DDRD/S(P).CHGV instruction etc. only at the time of necessity.
