Setting the Front Switches
Set the operating conditions with the CPU Bus Unit setting functions when an
NT30/30C and a CVM1/CV-series Host Link Unit is connected to the NT30/30C.
The CPU Bus Unit setting can be made directly from the Programming Device
(CX-Programmer) or the CPU Bus Unit setting information created with a Pro-
gramming Device can be transferred to the CPU Unit.
