Modbus – T2 Address mapping Example:
Input module | Output Module |
(XW000) | (YW001) |
In this example, the T2 is being used As a Modbus Remote Terminal Unit slave. A Modbus master can access The I/O or data registers in the T2.
See the following table for a Modbus to
T2 address mapping example.
T2E CPU Modbus Module
Modbus Address | T2 Address |
30000 | XW000 |
40001 | YW001 |
44352 | D0000 |
T2 Data Type
Input Register
Output Register
Data Register
Note: When dealing with I/O registers, make sure that the Modbus master is attempting to access only the I/O points that physically exist in the T2 system. For example, Holding Register 0 (40000) does not exist in the above example because there is no YW000 in the T2 system. In the above system, only have Holding Register 1 (40001) exists.
5.3. Restricted Registers
Registers D1406 to D1535 are reserved for “raw” data transmission with the EC300 loop controllers on the ECBUS network. These registers are not available when the
