Example 1: V2100 584/984 Mode
Find the MODBUS address for User V location V2100. PLC Address (Dec.) + Mode Address
1. Find V-memory in the table. V2100 = 1088 decimal
2. Convert V2100 into decimal (1088). 1088 + 40001 =
3. Add the MODBUS starting address for the
mode (40001).
Example 2: Y20 584/984 Mode
Find the MODBUS address for output Y20. PLC Addr. (Dec.) + Start Address + Mode
1. Find Y outputs in the table. Y20 = 16 decimal
2. Convert Y20 into decimal (16). 16 + 2048 + 1 =
3. Add the starting address for the range (2048).
4. Add the MODBUS address for the mode (1).
