9.1 PLC Connection 9-25
Available Device Memory
The available setting range of device memory varies depending on the PLC model. Be sure to set within the range available for
the PLC to be used. Use [TYPE] when assigning indirect device memory for macro programs.
*1 The unit number is required in addition to the device type and address. Convert byte address into word address when entering the data
on the editor if the memory device of the link unit is byte address.
For the unit number, set the decimal number of “XXX” included in the station I/O number “xxx0 H” of the link unit. For more information,
see page 9-16.
