Answer

Use the [Device Memory Map] setting.
Setting location: [System Setting] -> [Device Memory Map]

[Reading temperature controller/inverter data at regular intervals] (periodic reading)

  1. Click [System Setting] -> [Device Memory Map] -> [PLCn].
    The [Transfer Table: PLCn] menu is displayed.

     
     
  2. Click [Edit] -> [Device Memory Map Setting] to display the [Device Memory Map Setting [n]] window.
    Set [Function] as [Periodical Reading] and then configure [Reading Cycle] and [Target Device] (PLC or internal device memory).


    Example: Transferring temperature controller/inverter data to the PLC or internal device memory every 10 seconds
     
     
  3. Double-click on each cell and configure settings.
