Answer
Use the [Device Memory Map] setting.
Setting location: [System Setting] -> [Device Memory Map]
[Reading temperature controller/inverter data at regular intervals] (periodic reading)
- Click [System Setting] -> [Device Memory Map] -> [PLCn].
The [Transfer Table: PLCn] menu is displayed.
- 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
- Double-click on each cell and configure settings.
[Writing temperature controller/inverter data at regular intervals] (periodic writing)
- Click [System Setting] -> [Device Memory Map] -> [PLCn].
The [Transfer Table: PLCn] menu is displayed.
Click [Edit] -> [Device Memory Map Setting] to display the [Device Memory Map Setting [n]] window.
Set [Function] as [Periodical Writing] and then configure [Writing Cycle] and [Source Device] (PLC or internal device memory).
Example: Transferring data in PLC device memory to a temperature controller/inverter every 10 seconds
- Double-click on each cell and configure settings.
