NT Link Connection Auto-detect Function
8-1-1 Overview
When an NS-series PT is serially connected to a CS/CJ-series PLC through NT Link,
the PT’s communications settings (NT Link baud rate and the PT’s maximum unit
number setting) can be detected automatically. The PLC’s serial port settings are
automatically adjusted to match the detected PT communications settings and provide
an automatic connection between the PT and PLC (NT Link Auto Online Setting
function).
Computer (CX-Integrator)
CS/CJ-series PLC
•
Serial connection
(Toolbus or Host
Link, see note)
•
Network connection
Relay PLC
NT Link makes the serial connection
automatically (when using the RS-232C port).
The PLC
’
s serial port settings are
automatically changed to match the
NS-series PT
’
s serial port settings.
Overwrite
Note: Since the RS-232C port is used by the PT, the peripheral port
must be used to make a direct serial connection to the computer.
Note: The PLC’s serial port settings will be as follows after the automatic connection is
established:
•
•
•
Serial communications mode = NT Link (1:N)
Port baud rate = NS-series PT’s baud rate setting
Max. unit number in NT Link mode = Connected NS-series PT’s setting (Except
when the PT’s maximum unit number setting is 0, the PLC’s setting is 1.)
8-1-2 Procedure
The following example demonstrates the operation of the NT Link Connection
Auto-detect Function when an NS-series PT is connected to the built-in RS-232C port
of a CS/CJ-series PLC’s CPU Unit.
1. With the CX-Integrator online, right-click the CPU port listed below the target PLC
in the Online Information Window and select
Connect
from the pop-up menu.
2. A dialog box will be displayed to select one of the CPU Unit’s serial ports.
Select
Serial Port
(the RS-232C port) and click the
OK
Button.
