(1) The same serial port is used for the CX-Programmer and the NV-Design-
er, and only one of these can be online with the PT at the same time. For
example, an error message will be displayed if an attempt is made to
transfer screens from the NV-Designer while the CX-Programmer is con-
nected online.
(2) Do not use SPMA during recipe operations.
(3) SPMA can be used even when Auto Online - Direct Connection is select-
ed from the CX-Programmer's PLC Menu.
With an automatic online connection, the computer can be connected to the
PT using a USB or serial cable, and there is no need to make a setting in the
Change PLC Dialog Box.
1. Start the CX-Programmer. Select Auto Online – Direct Connection from
the PLC Menu.

methods depending on the PT model, and then click the Connect Button.
• NV3W: Serial Connection
• NV3W-V1, NV4W or NV3Q: USB Connection
3. The online connection will be made, and the ladder program or other data
can be transferred.
