Check the status of the entire network during CANopen communication.

1. Go to offline mode and touch [Peripheral Settings] on the item changeover switch.

2. [Peripheral Settings] screen opens. Touch [I/O Driver] and then [CANopen Driver].

3. [I/O Driver] screen opens. Touch [Master Configuration & Events].
   

4. [Master Configuration & Events] screen opens. Use the lamps to confirm the network's [CANopen Master Configuration] and [Global events]. (Example, CANopen Master Configuration: [Master], [Start slaves individually], [Master starts up itself], [CANopen master starts slaves], and [Master is SYNC producer]. Global events: [Master alone] indicates that the slave cable is disconnected.)
   See the following for [CANopen Master Configuration] and [Global events] details.
