Where to Begin?
Once you have the PSIM program installed and running you may
begin with the first of the Student Exercises. The first exercise
will lead you in a detailed step-by-step fashion through the process of
entering and testing simple relay logic program rungs using the PSIM
program. In these exercises it is imperative that you follow the sequence
of instructions exactly, and in the order presented.
Before proceeding with any exercise, the student should first ensure
that he or she has thoroughly reviewed the PLC instruction descriptions
relative to that section.
Psim simulation software has been
designed to operate on an IBM PC platform with the following
minimum hardware requirements:
- IBM 386 SX 25
- 640 KB main memory
- Hard Disk drive
- 1.44 MB, 3.5 inch diskette or
1.2 MB 5 1/4 inch diskette.
- VGA colour display.
Users may find that this software will, in fact, run on computers with
lesser power, however it should be noted that the speed of the animation
will be affected accordingly.
For Windows based installations follow the directions in the Setup program
when downloading from this site.
A "DOS" based Installation program is included with the PSIM distribution
diskette. This program will allow you to install all the required PSIM files
to a selected sub-directory on your Hard Drive. To run the the Install
- Place the PSIM distribution
diskette into either drive A: or B: of your computer.
- Log onto the selected drive (A: or B:)
- Type INSTALL at the DOS prompt.
The Install program will guide
through the installation procedure and allow you to either run
the PSIM program or return to DOS when the installation is
For Windows based installations PSIM
is started simply by double-clicking on the PSIM shortcut in the
*** For DOS based installations only: ***
Once PSIM is installed on your
Hard Drive the PSIM program may be started by typing PSIM once
you are in the selected PSIM sub-directory.
- CD C:\PSIM (use the DOS change directory command 'CD')
Note: If you selected a different
sub-directory name during the installation procedure you will
have to use it in place of the default 'PSIM' when changing
If you have purchased the optional
PSIM I/O interface board and intend to run PSIM with an External
PLC you will need to supply a command line option. See the PSIM
I/O interface manual for a description of starting PSIM with an
external programmable controller connected.
