2. Mechanism

The mechanism of communication is explained in this section to provide an understand- ing of how the robot controller and PLC operate via the CC-Link system.

qThe robot controller’s ON/OFF information is sent to the master station PLC via the network (CC-Link system cable).

wThe master station PLC’s ON/OFF information is set to the robot controller via the network (CC-Link system cable).

*The robot controller monitors the ON/OFF information at a 10ms cycle.

*The ON/OFF information consists of 16 points each of dedicated I/O points, 96 points each of general-purpose I/O points as bit information, and two words each of dedi- cated I/O words, 14 words each of general-purpose I/O words as word information.

If the following is executed with the robot program in the robot controller, the bit infor- mation will be sent to the master station PLC via the CC-Link system by q.

SO (20) = 1

Conversely, if the following is executed with the robot program, the bit information re- ceived from the master station PLC via the CC-Link system will be monitored by w, and will wait for the ON information.

WAIT SI (20) = 1

If the following is executed with the robot program in the robot controller, the word information will be sent to the master station PLC via the CC-Link system by q.

SOW (2) = 256

Conversely, if the following is executed with the robot program, the word information received from the master station PLC via the CC-Link system will be substituted in inte- ger variable A% by w.

A% = SIW (3)
