PSIM has more than paid for itself. Even though PSIM is DOS based and emulates. PLCs, it still remains an excellent tool for introducing. PLC programming. As a programmer I'm pleased to. I am even more pleased to see students. I am intent on not. SOFTWARE SPECIFICATIONS: Industrial Applications Software (Simulations): The PSIM software includes the following simulated processes: (1) Automated filling system.
Operator Station Panel and controls Conveyor with position sensors (photo switch) Hopper with motorized chute control Product Level Sensor Conveyor Motor Visual PLC Data Table Display including timers and counters (2) Batch Mixing system Simulation. Operator Control Panel 2 filler pumps and piping 2 flow meters on filler lines 1 mixing motor 1 high level sensor 1 low level sensor 1 gas fired heater (controlled valve) 1 temperature sensor 1 discharge pump 1 discharge flow meter 1 Visual PLC Data Table display including timers and counters (3) Intersection Traffic Light Control Simulation. Green Lights 2 Red Lights 2 Amber Lights Visual PLC Data Table Display including timers and counters 2 way traffic flow (4) Hardware Input and Output Simulator. SPST) 2 momentary normally open switches 2 momentary normally closed switches 8 controllable lights Visual PLC Data Table Display including timers and counters PLC Emulator Software. The PSIM software includes a full- featured built- in PLC Emulator package that runs concurrently on the same computer with the Industrial applications software (simulations) described above. With a single keystroke, the user may toggle back and forth between the display of the animated process simulation and the Ladder Rung Program Editor of the emulated PLC.
The Program Editor is both user friendly and full- featured. Students may add, delete and modify program- rungs, branches and instructions using simple menu selections. To test the new or modified ladder program, a single keystroke toggles the student back to the Process Simulation screen and places the PLC in the 'Run' mode. The process simulation will then react accurately to the student's newly programmed rungs which are constantly being scanned in the background by the PLC run- time emulator. By incorporating the Editor and run- time scanning of a PLC into software capable of running and interacting with the industrial process simulations, PSIM provides a single computer hi- tech solution to Programmable controller student training, whether running on the network of a computer Lab, or on the users own laptop computer. The PSIM system allows a simple low- cost solution to PLC training while attaining superior student concept retention. Minimum Hardware Requirements.

Load PSIM. self extracting setup file (2. MB)Installation Instructions. Download the self- extracting installation file to a temporary directory. Double click on the installation file to invoke the self- extracting setup program. The setup program will place a PSIM icon on your desktop for starting the program. Click on the PSIM icon, and ensure the program runs correctly.
You may now delete the download file from the temporary directory.
Programming Examples II . If we put 7 after the #, the overflow indicator will be activated (SM1.
Example 4: Using two timers, write a program so we have a pulse on PLC output with (TON = 1. TOFF = 1. 0 sec.)*TON: timer output on, TOFF: timer output off. Solution: Example 5: Using up- counter (CTU), make the PWM algorithm. PLC places for generating a series of pulses with fixed durations, one of these places is SM0.
