4.1 Basic Use of the 260IF Module
This chapter explains the basic use of the 260IF Module in the Master Mode and Slave Mode.
When using the 260IF Module, specify which mode is to be used, Master or Slave.
4.1.1 Master Mode
If the 260IF Module is set to Master Mode, the Slave devices on the DeviceNet and the CPU
Module will automatically exchange I/O data without being controlled by the program in the
CPU Module.
The following diagram shows how Master Mode works.
