14 How to use subnet
Description:
All subnets connected to MP can be used in the MP ,directly .
Format :
1-48-VAR101
Description : This is a register value of the Modbus ID 48 connected to pannel ID 1
Subnet Modbus ID =48
VAR101 : Register Number is 101
Notes : Register Number is PLC Address (Base 1). If you use Protocol Address (Base 0),
you must plus one to your current register number .
How to use in program:
EXAMPLE 1:GET THE VALUE OF THE REGISTER VALUE OF A SUBNET
10 REM *** THE VALUE OF 1-48-VAR101 ASSIGN TO VAR1 ***
20 VAR1 = 1-48-VAR101
EXAMPLE 1:SET THE VALUE OF THE REGISTER VALUE OF A SUBNET
10 REM *** VAR1 ASSIGN TO THE VALUE OF 1-48-VAR101 ***
20 1-48-VAR101 = VAR1
NOTE: When you use the register number ,you must know whether the register number can have the property of R/W.
Example show :
10 VAR1 = 1-48-VAR101
20 VAR2 = 1-48-VAR102
30 VAR3 = 1-47-VAR101
40 VAR4 = 1-47-VAR102
50 VAR5 = 1-20-VAR101
60 VAR6 = 1-20-VAR102
70 VAR7 = 1-19-VAR101
80 VAR8 = 1-19-VAR102
90 VAR9 = 1-44-VAR101
100 VAR10 = 1-44-VAR102
110 VAR11 = 1-46-VAR101
120 VAR12 = 1-46-VAR102
130 VAR13 = 1-49-VAR101
140 VAR14 = 1-49-VAR102
