			Alarm
13	Reset RTU-DNET	N/A	Reset the configuration of RTU-DNET to default settings.
			For you to decide whether to add control word and status word
	Add control word		to I/O data. When you choose not to do it, the I/O data in
			RTU-DNET and DeviceNet master will not include control word
14	and status word to	N/A
			and status word. If you choose to add them in, the I/O data in
	I/O data
			RTU-DNET and DeviceNet master will include control word and
			status word.
			For you to set up the work mode of the special module
15	Work mode	N/A	connected to RTU-DNET. When set to “auto mode”, RTU-DNET
			will configure default CR of the special module as DeviceNet I/O
			mapping data. When set to “custom mode”, you can configure
			any CR in the special module as DeviceNet I/O mapping data.
