*_Sw2SlavFixAloc1C Slave Fixed Allocation
md Setting 1 Switch
*_Sw2SlavFixAloc2C Slave Fixed Allocation
md Setting 2 Switch
*_Sw2SlavFixAloc3C Slave Fixed Allocation
md Setting 3 Switch
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.
