Notes

The RT statistics displays are not supported under TwinCAT for an EP6601-0002-RT device.
Solution: Alternatively, corresponding CoE parameters can be read for diagnostic purposes.
The Publisher features "OnChangeOnly" and "DataExchange (Divider/Modulo)" are not supported in connection with EP6601-0002.
Solution: The sending of the configured Publisher variables can be cyclically prevented by DevCtrl.
If a Publisher is set up on an EP6601-0002, the CycleIndex of the Publisher must be operated by the user. On a PC, however, they are incremented by TwinCAT.
The following is recommended for diagnosing a network variable connection:
1. Monitor LinkState in the "DevState" of the RT device (Device --> Inputs --> DevState). DevState = 0 is the target state.
2. Monitor the Quality and CycleIndex in the Subscriber.
The Link LED in the EP6601-0002 only indicates the state of the cable connection, not that of any network variable connection that may exist.
If the EP6601-0002 is used exclusively for network variable traffic, the "Connect to TCP/IP Stack" button should be disabled. See chapter Virtual switch.
A maximum of 32 Publishers and Subscribers are permitted for each EP6601-0002.
