7.5. Parameter access method

Parameter access is allowed by using nviParamCmd and nvoParamResp network variables. The structure format is shown in below table.

Field	Length	Description
		Command
learn	1 byte	2 (LN_LEARN_VALUE)	: Write
		3 (LN_REPORT_VALUE)	: Read
selector	2 bytes	Parameter address (unsigned value)
value[0]	1 byte	0 at successful
value[0]	1 byte	0xFF at occurred error
		0xFF at occurred error
value[1]	1 byte	0
value[2]	1 byte	The most significant 2 hex bytes of data
value[3]	1 byte	The least significant 2 hex bytes of data
day ,hour, minute,	Total	N/A
second, millisecond	7 bytes

- Example 1: Read access

A controller node reads the value of Trip code (address FC90). Now, ol1 trip (trip code is 13 decimal) occurs. The value is 000D hex. The controller node sends/receives the following data.

	Field	Send (nviParamCmd)	Receive (nviParamResp)
	learn	LN_REPORT_VALUE	LN_REPORT_VALUE
	selector	FC90 hex	FC90 hex
	value[0]	N/A	0
	value[1]	N/A	0
	value[2]	N/A	00 hex
	value[3]	N/A	0D hex
	day ,hour, minute,	N/A	0
	second, millisecond	N/A	0
	second, millisecond

- Example 2: Write access

The controller node writes cumulative energy clear command (address FA20). The data value is 0002 hex. The controller node sends/receives the following data.

	Field	Send (nviParamCmd)	Receive (nviParamResp)
	learn	LN_LEARN_VALUE	LN_LEARN_VALUE
	selector	FA20 hex	FA20 hex
	value[0]	00 hex	00 hex
	value[1]	00 hex	00 hex
	value[2]	00 hex	00 hex
	value[3]	02 hex	02 hex
	day ,hour, minute,	N/A	0
	second, millisecond	N/A	0
	second, millisecond

N.B.: After sending cumulative energy clear command, 0000 hex should be re-written into FA20.
