2. In
the
Network
tab, check the Unit No, usually 0 for connecting to a single PLC or the
multi drop number for an RS422 connection.
3. In
the
Driver
tab, check the port on the computer for connection to the PLC and enter it in
the
Port Name
field.
4.
Select the
Baud Rate
,
Parity
,
Data Bits
and
Stop Bits
from the drop-down lists available
for the selected port.
5.
For the
Modem
tab, refer to Microsoft Windows documentation.
6.
Select the
OK
pushbutton to save these settings, or select the
Cancel
pushbutton to abort
the operation.
Note:
For CS/CJ/CP-series PLCs, SYSMAC WAY dip switch five on the front panel must
be set to ‘OFF’.
Toolbus
Toolbus operates in a similar manner to SYSMAC WAY. The connection is made to a PLC using its peripheral
port.
The following connection is required:
♦
RS232 connection via a standard serial port on the computer (COM1 etc.) using either CIF01 or CIF02
cable.
The
Driver
tab is similar to that belonging to SYSMAC WAY; however, for some PLCs fixed values are
entered and these cannot be altered (see table below). The CS/CJ/CP-Series PLC Toolbus configuration ensures
successful connection to the PLC every time, independently of the rate specified by the user provided the
Auto
Baud Rate Detection
setting has been checked.

Serial Networks
When connecting a computer to a serial network of PLCs, each PLC needs to be configured so that it has a
different Unit number. The Unit number for C-series PLCs should be configured as follows:
CPU-mounted Host Link unit:
DIP switches on back of unit
Rack-mounted Host Link unit:
Rotary switches on front of unit
Direct CPU RS232 port:
Internal DM settings
Direct CPU Peripheral port:
Internal DM settings
The Unit number for CV-series PLCs and CS/CJ-series PLCs should be configured as follows:
Rack-mounted Host Link unit:
Unit Setup dialog
Direct CPU RS232 port:
Host Link settings dialog
Direct CPU Peripheral port:
Fixed as Unit 0
Remote SYSBUS/2 Peripheral port:
Fixed as Unit 0
Note:
The unit number rotary switches on the top of CV-series SIO units are the unit
number of that Special I/O Unit on that PLC rack and not the Unit number of the PLC
on the serial network.
Online connection is possible through a Serial Communications Board or Unit with unit version 1.2
or later mounted to a PLC directly connected via the peripheral bus (Toolbus) or Host Link (or to a
