Sequentially writes data into 0xFFF0~0xFFF3. Data will be sent to iR-PU01-P when written
into 0xFFF3.

Step1: Sequentially writes data into 0xFFF4~0xFFF5. Reading iR-PU01-P object starts when
data is written into 0xFFF5, and the data will be placed in 0xFFF6~0xFFF7.
Step 2: Read data of 0xFFF6~0xFFF7 Object.

Modbus Mapping
The following is an example showing that when iR-ETN is connected with multiple
modules, the address mapping and input/output bit mapping can be as follows:
