Toolbus
Click the Driver Tab and set the following settings as required.
Port Name: Select the computer’s COM port from the drop-down list.
Baud Rate: Select the baud rate (bits/s) from the drop-down list.
Baud Rate Auto-Detect: Clear this selection to connect with the baud rate set on the
computer, ignoring the baud rate of the serial port on the
CPU Unit. To disable automatic detection of the baud rate,
the DIP switch on the CPU Unit must be set as follows:
For peripheral port connection: Pin 4 of the DIP switch must
be OFF (automatic detection of communications settings:
use Programming Console or CX-Integrator settings).
For RS-232C port connection: Pin 5 of the DIP switch must
be ON (automatic detection of communications settings: use
CX-Integrator settings).
Note
For automatic baud rate detection with the Toolbus protocol, the baud rate setting on
the computer is used and the serial port on the CPU Unit is set to the same value.
For automatic online connections, the communications settings (device type, serial
communications mode, baud rate, and other communications settings) of the serial
port on the CPU Unit are detected and the device type information on the computer
are set to the same values.
