3 MOTION DEDICATED PLC INSTRUCTION
(5) Order of instruction execution
Methods to control using execution data after it is transmitted from the PLC CPU
to the Motion CPU are shown below.
(a) Method to execute after data is written to the shared memory area (Multiple
CPU high speed transmission area).
Write the data from PLC CPU to the shared memory area (Multiple CPU
high speed transmission area) of the self CPU, and then it can be utilized for
Motion dedicated PLC instruction execution.
