4.6 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 TT 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.)

* There should not be inconsistencies between the port numbers of I/O
parameters No. 14 and No. 15 and the number of occupied stations.
The relationships between I/O signals are shown below by taking s case where the number of I/O points of TT is
set to 112 or more and 192 or less (two stations occupied) for example.
(1) TT remote I/O areas and remote register areas
Remote input: Port No. 48 to No. 111
Remote output: Port No. 348 to No. 411
Remote address (input): Port No. 112 to No. 239
Remote address (output): Port No. 412 to No. 539
(Note) Since ports No. 128 to No. 143 and No. 428 to No. 443 are the system areas for the remote device stations on
the PLC side, they cannot be used.
