10-3-4 Procedural Example
To explain details of settings simply, procedures are described as tutorial with examples depending on
the configuration. The values such as IP Addresses, Network Addresses described below are the ex-
amples so please set those in accordance with the actual environment.
■ Serial Connection between Computer and PLC and Serial 1:N NT Link
between PLC and PT Set for Transferring Screen Data to a PT through
a PLC.
This section describes data transfer from the NS-Designer to a PT connected either an RS-232C port
or a peripheral port on the PLC’s CPU Unit by a Serial (1:N NT Link) connection through a PLC con-
nected with the computer by serial (Peripheral bus) connection. In this example, the cable between the
computer and the PLC is connected to the peripheral port on the PLC and the cable between the PLC
and the PT is connected to the RS-232C port on the PLC.
