We have been given the task of adding some functionality to an existing AB SLC that uses FlexIO with DeviceNet. We are trying to upload the current network configuration by configuring a DeviceNet driver in RSLinx, but are always greeted with "KFD32 Error: Operation timed out".
We checked the AB knowledgebase site, which points out possible problems:
1. DeviceNet network not working properly
2. KFD is not connected on the network
3. Incorrect Baud rate or MAC ID
4. COM Port conflict
We are sure the problem is not no. 1 because the system is in operation, and from all reports is operating correctly. No. 2 seems unlikley because we can see the PLC over the same connection when we configure the DH485 driver. No.4 also seems unlikley because we deleted all the other drivers to avoid this problem. No. 3, to us, is the only possible cause, however as we are unsure of the network baudrate, we tried all of the available, each with the same error message.
