4.18.3 Data operation of intelligent function module by Motion SFC program

4.18.4 Data of refresh device

4.18.5 Precautions when using SSCNET /H head module

In addition to refresh of data by device, data read/write operations to the buffer
memory of intelligent function modules on the SSCNET /H head module can be
executed by the RTO and RFROM instructions of Motion SFC programs.
Refer to "Q173D(S)CPU/Q172D(S)CPU Motion controller (SV13/SV22) Programming
