Item
Control signal(*1)(*3) Data will be written by turning bit0 ON. NC and PLC write asynchronously.
When the writing is finished, the bit0 under "Status" of the writing result turns
ON.
When the bit0 under "Status" turns ON, turn OFF the bit0 of the control sig-
nal.
Section No.(*1) Designate data type
Section sub-ID No.(*1) Designate part system No. (1 to maximum number of part system for each
model)
Sub-section No.(*1) Designate data
Data No.(*1) Designate axis No. used in the part system and variable No., etc.
(The axis No. is 1 to maximum number of axes for each model)
Writing method(*1) 0: Write up to 4 consecutive data from the designated data No.
