3. Communication with master station PLC
The method for communicating with the master station PLC by using the robot program
when the CC-Link system is correctly connected is explained in this section.
3.1 Receiving
data
Data is received by reading the master station PLC output device data with the robot
controller’s input port. The correspondence of the master station PLC’s output device
numbers and robot controller’s input port numbers is shown below.
Master station
output device No.
Robot controller
input port No.
Master station
output device No.
Robot controller
input port No.

CAUTION
SIW(0) and SIW(1) are viewed as dedicated input ports. The robot controller
handles these ports as input ports of meaningful data, so do not use them as
general-purpose input ports.
Set these ports to "0" in most cases.
