Using the D2–DCM with MODBUS
Data Communications Module, 2nd Edition, 2/03
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).
PLC Address (Dec.) + Mode Address
V2100 = 1088 decimal
1088 + 40001 =
41089
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).
PLC Addr. (Dec) + Start A Mode
Y20 = 16 decimal
16 + 2048 + 1 =
2065
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).
PLC Address (Dec.) + Mode Address
TA10 = 8 decimal
8 + 3001 =
3009
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).
PLC Addr. (Dec) + Start A Mode
C54 = 44 decimal
44 + 3072 + 1 =
3117
