Toshiba T2 Series user manual Restricted Registers, Modbus - T2 Address mapping Example

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 EX10-MML11 is used as a Modbus slave module. Do not use these registers.
