The following examples show how to generate the Modbus address and data type for hosts
which require this format.
Example 1: V2100
Find the Modbus address for User
V location V2100.
1. Find V memory in the table.
2. Convert V2100 into decimal (1089).
3. Use the Modbus data type from the table.
Timer Current Values (V)
Counter Current Values (V)
V Memory, user data (V)
Example 2: Y20
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 (2049).
Outputs (Y)
Control Relays (CR)
Modbus data type from the table.
Example 3: T10 Current Value
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. Use the Modbus data type from the table.
Timer Current Values (V)
Counter Current Values (V)
Example 4: C54
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 (3073).
4. Use the Modbus data type from the table.
Outputs (Y)
