Example 1: V2100 584/984 Mode
Find the Modbus address for User V location
V2100.
1. Find V memory in the table
2. Convert V2100 into decimal (1088).
3. Add the Modbus starting address for the mode (40001).
Example 2: Y20 584/984 Mode
Find the Modbus address for output Y20.
1. Find Y outputs in the table.
2. Convert Y20 into decimal (16).
3. Add the starting address for the range (2048).
4. Add the Modbus address for the mode (1).
Example 3: T10 Current Value 484 Mode
Find the Modbus address to obtain the
current value from Timer T10.
1. Find Timer Current Values in the table.
2. Convert T10 into decimal (8).
3. Add the Modbus starting address for the mode (3001).
Example 4: C54 584/984 Mode
Find the Modbus address for Control Relay
C54.
1. Find Control Relays in the table.
2. Convert C54 into decimal (44).
3. Add the starting address for the range (3072).
4. Add the Modbus address for the mode (1).
Determining the
D
Diirreecctt
NET Address
Addressing the memory types for
Direct
NET slaves is very easy. Use the ordinary native
address of the slave device itself. To access a slave PLC’s memory address V2000 via
Direc
t
NET, for example, the network master will request V2000 from the slave.
