A DVP-10PM series motion controller can read the data in a control register in
a special module by means of the instruction.
Please refer to the additional remark on the instruction TO for more information
about the numbering of special modules.
Example
The value in CR#29 in special module 0 is read, and then stored in D0 in the
motion controller used. The value in CR#30 in special module 0 is read, and
then stored in D1 in the motion controller used. The two values are read at the
same time.
When X0 is ON, the instruciton is executed. When X0 is turned OFF, the
instruction is not executed, and the values which are read remain unchanged.
