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
4205/5205-TS-104S-PDPS Module Database Address
400 Word

The measured normalized points use a data representation defined by the
protocol specification, where each bit represents a value as follows:
Bit 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1
