■Refresh device setting (CPU side)
Set the device (Input: RX, RWr/Output: RY, RWw) for storage of link data. Motion CPU device is set using automatic refresh
by cyclic transmission of the SSCNET/H head module. Link devices (RX, RWr, RY, RWw) of the Motion CPU are
automatically assigned in MT Developer2.
Link devices (RX, RWr, RY, RWw) of the Motion CPU are used only for internal processing. These cannot be
used in user data such as Motion SFC programs etc.
• Device name
Set the device name for the bit device or word device that stores link data. Refer to device list for bit device and word device
names that can be set. (Page 75 Device List)
• Module I/O No./10h(**)
If a module access device (U\G) is set for the device name, set the I/O No. for the module access device (U\G) in which
the link data being input is stored. Refer to device list for the range of module access devices (U\G) that can be set.
(Page 75 Device List)
• Points
Set the points of the device that stores link data. Set the points of the device in units of words. The total points for input
(RX+RWr), and output (RY+RWw) must be 64 bytes or less.
Device
*1
Bit device
Word device
*1 Set in units of 16 points (1 word).
• Start
Set the start device number in which link data is stored with a bit device or word device. For bit devices, set a multiple of 16.
Refer to device list for the range of bit devices and word devices that can be set. (Page 75 Device List)
