1 FUNCTIONS AND CONFIGURATION
System Configuration 1-5
◆ Multiple CPU system
This function allows multiple CPU modules in the multiple CPU system to use one master/local module.
Programmable controller CPU module (CPU No.1) can perform standard communication, and robot CPU module
of robot controllers (CPU No.2 to No.4) can perform safety communication with the master station individually.
