The NV3W and NV3Q provide IP65 protection against dust and water drops.
The NV3W-V1 and NV4W provides IP67 protection.
You can transfer, monitor, or debug ladder diagrams in a PLC from the CX-
Programmer running on a computer connected to the PT with the convenient
SPMA (Single Port Multiple Access) function while the PLC and PT are com-
municating with each other.
This function is effective during system installation and debugging.
Ladder diagrams can be transferred
and the PLC can be monitored from
the CX-Programmer.
CX-Programmer
Communicate through the PT.
Note The CX-Programmer and NV-Designer, however, cannot be con-
nected online at the same time.
You can use the Write Address function to execute operations to set or reset
bits, set values, perform calculations, and more in PLC memory when condi-
tions in the PLC are met. This reduces the load on the ladder program in the
PLC in communicating with the PT.
