5.2.1 Overall address configuration example
In here, shows the overall address construction when four units of the EC connection unit are
connected to the REC gateway unit.
Note that CC-Link and DeviceNet should be assigned to the word addresses while PROFIBUS-
DP to the byte addresses.
[For CC-Link]
The following page shows a CC-Link configuration example.
Fixed 8-word region is assigned to the bit register (RX/RY), while the region for each axis is
assigned to the word register (RWr/RWw).
PLC output ⇒ REC REC ⇒ PLC input
Output register High byte Low byte Input register High byte Low byte
RY00F ~ 000 Reserved RX00F ~ 000 Gateway status signal
RY01F ~ 010 System Domains RX01F ~ 010 System Domains
Output register Input register
RWw 00H Control signal (Unit 0) RWr 00H
Status signal (Unit 0)
RWw 01H Control signal (Unit 1) RWr 01H
Status signal (Unit 1)
RWw 02H Control signal (Unit 2) RWr 02H
Status signal (Unit 2)
RWw 03H Control signal (Unit 3) RWr 03H
Status signal (Unit 3)
*1 Regardless of the number of option units, the occupied size should be Ver. 1.10, extension
cyclic multiplied by one and number of occupied stations one.
*2 The EC connection unit occupies domains and axis numbers for four axes (one word) even
though not all of four axes are connected.
[For CC-Link IE Field]
Fixed 1-word region is assigned to the bit register (RX/RY), while the region for each axis is
assigned to the word register (RWr/RWw).

* Regardless of the number of option units, the occupied size should be 32 points of RX/RY and 4
points of RWw/RWr.
*2 The EC connection unit occupies domains and axis numbers for four axes (one word) even
though not all of four axes are connected.
