Step 4: Change the Slave Enable Switch to TRUE
Change
*_Sw2SlavEnblCmd
(Slave Enable Switch) to TRUE. This will allocated the fixed allocation
areas as slave areas and the DeviceNet Unit will start slave remote I/O communications. Slave com-
munications will run automatically after that whenever the power is turned ON.

Step 5: Define User-defined Variables
Define a user-defined variable for the area to which each slave is allocated. By using the user-
defined variable, the user program can access the allocation area of the slave.
