Here you are able to force the inputs simply byĬlicking on the button and examining the result.
LADSIM's debugging simulator gives you access to the various inputs used in your program. The Debugging Simulator is activated by clicking on the simulate button or the debugger from the simulate menu. LADSIM has a unique testing facility built into the package so you can test and debug the ladder programs created in
Testing your Diagrams Once you have created a piece of ladder code it is important to ensure its correct operation before applying it to a real control problem. As your program evolves, you will need to add more rungs and further controls, all of which are just a simple click with LADSIM. You can easily change these references by double-clicking on the control. For example, if you drop a Normally Open Contact onto a rung, the following box will appear that allows you to input your control references. In LADSIM, once you have dropped a control onto a rung, a box appears where you can enter information about that control. Creating a Ladder Diagram A ladder diagram can be quickly generated by 'dragging' the required controls from the control panel and dropping them on the rung. LADSIM uses the same symbols to produce the ladder code on screen and each one is defined below : LADSIM features a total 12 inputs, 12 outputs, 6 timers, 6 counters, 16 flags, 4 shift registers and 12 reset functions for the timers and counters.
The LADSIM Controls Ladder logic programs are made up of symbols that represent the various inputs and outputs of the plant equipment we wish to control. This includes the standard buttons of LADSIM and allows you to start a new diagram, open an existing file, print, save and comment your ladder diagram. This contains the ladder symbols that are used to create the ladder diagram. Each time you add or edit a rung, the result will be shown here.Ģ.
This is where the ladder code is displayed. The LADSIM Editing Screen The main screen of LADSIM is where the main ladder program is created.
While LADSIM can be used as a stand-alone teaching aid with its library of internal simulations, it also has the added benefit of being capable of controlling external applications via one of our PC Internal Interface cards. The simulations provided within LADSIM are a Traffic Light, Annunciator, Car Park, Lift, Drinks Machine, Packing Line and Bottling Plant. For each simulation you must develop the necessary ladder code to effect safe control of the scenario. LADSIM incorporates seven 'real' process simulations that will test your understanding of Ladder Logic Programming. Extra rungs can be added with the click of a button, together with branches to form more complex programs. Each function is simply 'dragged' onto the ladder rung with name tags assigned via a pop-up window. With Inputs, Outputs, Timers, Counters, Flags and Shift Registers available, you can develop ladder programs quickly and easily. LADSIM is a fully-functional Ladder Logic Editor and PLC Simulator that incorporates all the basic functions used in PLC Programming.
Being software-based, LADSIM is available in a multiuser format that cuts the cost of setting-up multiple stations in your lab, thus bypassing those budgetary problems.
Even if you choose a particular brand, the cost of equipping your laboratory with that PLC and its associated programming software is very often above the available budget. With many different PLC manufacturers in the marketplace, choosing a PLC to teach programming techniques can be a difficult decision. LADSIM - Ladder Logic Editor and Programmable Logic Controller Simulator Bytronic has introduced a new Windows-based training package, LADSIM, that converts your existing PC into a virtual PLC.
