Monitor Points Addressing
As discussed before, the monitor points must be configured in a database area in
the 4205/5205-TS-104S-PDPS module.
The monitor data types are described in the following table:
Data Type Data Size Addressing Type
M_SP_NA 1 bit Bit
M_DP_NA 2 bits Bit
M_ST_NA 1 byte Byte
M_ME_NA 1 word Word
M_ME_NB 1 word Word
M_ME_NC 2 word Double-Word
M_IT_NA 2 word Double-Word
M_SP_NA and M_DP_NA
The monitored single-point (1 bit) and monitored double-point (2 bits) types both
occupy bit-addressing. For example, if you configured the following points:
# Point # DB Address Group(s) IV DB Bit
# ------- ---------- -------- -------------
START
100 1600 80000000 0
101 1601 00000200 0
102 1602 00000400 0
END
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 monitored double-point uses two bits with bit-addressing. It typically
represents the ON/OFF states where:
01 = OFF
10 = ON
M_ST_NA
The monitored step-point uses one byte with byte-addressing.
For example, if you configured the following points:
# Point # DB Address Group(s) IV DB Bit
# ------- ---------- -------- -------------
START
300 40 80000000 0
301 60 00000200 0
302 81 00000400 0
END
