PL

sNet II Upload/Download Program

Description

PL

µ

SNet 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 PL

µ

S Programmable Limit Switch,

PL

µ

SNet II can transfer programming values between the computer and the controller

in either direction. PL

µ

SNet II includes its own communications software with selection

of baud rate, PL

µ

S controller address, and the computer’s COM port. No other commu-

nication software is needed.

Functions

PL

µ

SNet 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 PL

µ

S controller. PL

µ

SNet II also provides

a text editor to view and change the contents of an ASCII file.

Applications

Hard Copy Reference—Using PL

µ

SNet II, a PL

µ

S 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 PL

µ

S controllers in the plant.

Archival Storage—The ASCII file containing a PL

µ

S 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, PL

µ

SNet II can be used to download the ASCII file to the

controller to restore normal operation.

Programming Multiple Units—If several PL

µ

S controllers will have the same values,

one controller can be programmed correctly and its setpoints uploaded to a PC using

PL

µ

SNet II. The programming can then be downloaded to the other PL

µ

S 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 PL

µ

SNet II Communications Software Program includes these materials:

(1) Introduction sheet.

(1) One disk containing the PLUSNET.EXE file.

Cable

To use PL

µ

SNet II, a serial communications cable is required to connect the PL

µ

S

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 PL

µ

S Programming and Installation Manual.

Installation

Copy the PLUSNET.EXE file to the desired directory on the PC.

Operation

Connect the PC and the PL

µ

S 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.
