PLµsNet II Upload/Download Program
Description PLµSNet II is a DOS program that will run on most IBM-PC compatible computers.
When the serial port of the PC is connected to a PLµS Programmable Limit Switch,
PLµSNet II can transfer programming values between the computer and the controller
in either direction. PLµSNet II includes its own communications software with selection
of baud rate, PLµS controller address, and the computer’s COM port. No other commu-
nication software is needed.
Functions PLµSNet II provides two main functions: Uploading a controller’s complete set of pro-
gramming values from the controller to an ASCII file on the PC; and downloading the
contents of an ASCII from a computer to the PLµS controller. PLµSNet II also provides
a text editor to view and change the contents of an ASCII file.
Applications Hard Copy Reference—Using PLµSNet II, a PLµS controller’s programming can be
saved as an ASCII file and printed out for reference. The printout can be used to study
line operation or to program other PLµS controllers in the plant.
Archival Storage—The ASCII file containing a PLµS controller’s programming can be
stored on a hard drive or floppy disk. In the event of accidental alteration or erasure of
the controller’s programming, PLµSNet II can be used to download the ASCII file to the
controller to restore normal operation.
Programming Multiple Units—If several PLµS controllers will have the same values,
one controller can be programmed correctly and its setpoints uploaded to a PC using
PLµSNet II. The programming can then be downloaded to the other PLµS controllers,
eliminating the need to manually reenter setpoints for each controller.
Modify Programming—Once a program has been saved as an ASCII file, it can be
studied and edited to create other versions of the program.
Contents The PLµSNet II Communications Software Program includes these materials:
(1) Introduction sheet.
(1) One disk containing the PLUSNET.EXE file.
Cable To use PLµSNet II, a serial communications cable is required to connect the PLµS
controller to an IBM compatible personal computer. This cable can be purchased from
Electro Cam Corp., or it can be built by the customer using the wiring information shown
in the PLµS Programming and Installation Manual.
Installation Copy the PLUSNET.EXE file to the desired directory on the PC.
Operation Connect the PC and the PLµS controller with a communications cable and turn both
units ON.
Start PLUSNET.EXE from the DOS command line, or from a DOS window within
Microsoft Windows. The menus in the program are self-explanatory.
