3.1.8 Data in remote registers
Addresses in PLC are assigned to the remote I/O addresses and remote register areas that correspond to
the station number set on the CC-Link board and the number of occupied stations set by the PLC parameter,
in steps of 16 points (one word) in order of X-SEL port number.
Setting the I/O parameter No. 120 to “0” allows the data in one word to be transmitted by reversing the
order of the higher-order byte (higher-order 8 bits) and the lower-order byte (lower-order 8 bits) in the
communications area with the PLC remote register. (Remote I/O areas are not changed.)

(Main application of Ver. 0.55 or later)
The relationships between I/O signals are shown below by taking s case where the number of I/O points of X-SEL
is set to 112 or more and 192 or less (two stations occupied) for example.
(1) X-SEL remote I/O areas and remote register areas
Remote input: Port No. 0 to No. 63
Remote output: Port No. 300 to No. 363
Remote address (input): Port No. 64 to No. 191
Remote address (output): Port No. 364 to No. 491
Note: Since ports No. 48 to No. 63 and No. 348 to No. 363 are the system areas for the remote device stations on the
PLC side, they cannot be used.
