4.1.2 Slave Mode
If the 260IF Module is set to Slave Mode, the 260IF Module will automatically exchange I/
O data with the Master without being controlled by the program in the CPU Module.
The Master can be a 260IF Module mounted on another MP920 or any other DeviceNet-
conforming device.
The following diagrams show how the Slave Mode works, using the data exchange between
nodes as an example.
