These points would be used as follows:

Inf. Object Address

Module Database Address

100

Bit 0 of word 100

101

Bit 1 of word 100

102

Bit 2 of word 100

The protocol specification defines a qualifier value that is set by the master to
determine the duration of the pulse (short, long or persistent). Configure the
parameters below to set the duration of the short and long pulses:

Short Pulse Time : 2000 #MSec for short pulse command

Long Pulse Time : 10000 #MSec for long pulse command

C_RC_NA

The step-point command uses one byte with byte-addressing.

For example, if you configured the following points:

# Monitor Monitor

# Point # DB Address Point # DB Addr

# ------- ---------- ------- -------

START

300 40 0 0

301 60 0 0

302 81 0 0

END

These points would be used as follows:

Inf. Object Address

Module Database Address

300

Low Byte of word 20

301

Low Byte of word 30

302

High Byte of word 40

C_SE_NA and C_SE_NB

The measured normalized point command uses one word with word-addressing.
For example, if you configured the following points:

# Monitor Monitor Require

# Point # DB Address Point # DB Addr Select

# ------- ---------- ------- ------- -------

START

400 10 0 0 0

401 12 0 0 0

402 18 0 0 0

END

These points would be used as follows:

Inf. Object Address

MVI69-101S Module Database Address

400 Word

10

401 Word

12

402 Word

18

The measured normalized points use a data representation defined by the
protocol specification, where each bit represents a value as follows:
