address seen from a remote I/O station."
Specify the module number using the last "I/O address seen from a remote I/O
station" regardless of the settings of the common parameters set at the master
station of the MELSECNET/10 remote I/O net.

• The special function module's buffer memory contains 16 bits (one word) per address
and reading/writing operations between the PLC CPU and special function module
are performed using the FROM/TO instructions. When reading/writing from the
special function module's buffer memory to the communication module or vice versa,
the operation is performed in units of 8 bits (1 byte) per address.
The addresses to specify in the communication module (hexadecimal) are obtained
by the following conversion from addresses for the FROM/TO instructions.
