3.2.4 Write to DDWR Q motion CPU device command
This command is used to directly write the device data in the Q motion CPU to the Q-
PLC CPU.
(1) Setting the number of data points to be written
Set the number of data points to be written, indirectly.
To write the data for 10 points from D0 of local machine (No. 1 machine) to
D100 and following of No. 2 machine, it is executed as follows.
H3E1 D30 D0 D100 M0
MOV
D31
K10
SP.DDWR
Setting the number of
write data
(2) Execution timing
The data of designated device is written to the Q motion CPU at the rising edge
(OFF → ON) of the DDWR command execution command.
