Appendix A
Appendix 3: DeviceNet Explicit Messages
User-specified NE1A parameters can be read and written by sending DeviceNet explicit messages to the
NE1A-series Controller. The NE1A-series Controller will process the received messages and return
responses. This appendix describes the messages that are supported by the NE1A-series Controller.
