Serial Line Configuration
Serial Line Configuration
Introduction
The Serial Line configuration window allows you to configure the physical parameters of a serial line (baud rate, parity, and so on).
Serial Line Configuration
To configure a Serial Line, double-click Serial line in the Devices tree.
The Configuration window is displayed as below:
218
The following parameters must be identical for each serial device connected to the port.
Element
Baud rate
Parity
Data bits
Description
Transmission speed in bits/s
Used for error detection
Number of bits for transmitting data
Stop bits Number of stop bits
Physical Medium Specify the medium to use:
RS485 (using polarisation resistor or not)
RS232
Polarization
Resistor
Polarization resistors are integrated in the controller. They are switched on or off by this parameter.
The Serial Line port(s) of your controller are configured for the Machine Expert protocol by default when new or when you update the controller firmware.

Serial Line Configuration
The serial line ports of your controller are configured for the Machine Expert protocol by default when new or when you update the controller firmware. The Machine Expert protocol is incompatible with that of other protocols such as Modbus Serial Line. Connecting a new controller to, or updating the firmware of a controller connected to, an active Modbus configured serial line can cause the other devices on the serial line to stop communicating. Make sure that the controller is not connected to an active Modbus serial line network before first downloading a valid application having the concerned port or ports properly configured for the intended protocol.
NOTICE
INTERRUPTION OF SERIAL LINE COMMUNICATIONS
Be sure that your application has the serial line ports properly configured for Modbus before physically connecting the controller to an operational Modbus Serial Line network.
Failure to follow these instructions can result in equipment damage.
