• To switch between the Network operation mode and the External operation mode
1) Set Pr.79="0" (initial value) or "2, "6" or "7". (When Pr.79 ="7" and the X12 (MRS) signal is ON, the operation mode can
be switched.)
2) Set Pr.340 Communication startup mode selection ="0" (initial value), "1" or "2".
3) Set "66" in one of Pr.178 to Pr.189 to assign the NET-External operation switching signal (X66) to a terminal.
4) When the X66 signal is ON, Network operation mode is selected. When the X66 signal is OFF, the External operation
mode is selected.

When "Pr.550 NET mode operation command source selection = "0" (communication option control source)" and no communication option is
connected, the External operation mode is selected.

When the X16 signal is OFF, the PU operation mode is selected. Also, when the X65 signal is assigned, the operation mode follows the ON/OFF
state of the X65 signal.
NOTE
• The priority of Pr.79 and Pr.340 and signals is Pr.79 > X12 > X66 > X65 > X16 > Pr.340.
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
