Communicate with Serial Devices
This chapter explains how to use a serial device with your SoftLogix system.
Details on configuring your system for a serial device and examples are included.
Configure Your System for a
Serial Device
For the SoftLogix controller to operate with a serial device, you need
the following:
• A computer where the SoftLogix controller resides to have a serial port
• RSLinx software to configure the serial communication driver
If a remote computer communicates with the SoftLogix controller via a
serial connection, the remote computer must have the serial driver
installed. The computer with the SoftLogix controller does not need the
serial driver to connect to other devices over a serial device
• Logix Designer application to configure the serial port of the controller
