PC-Sim: PLC simulator
PC-Sim is the AW-SYS module that simulates programmable logic controllers (PLCs).
An excellent tool when teaching how to program a PLC. When run on a personal computer, it enables the user:
In addition, as a result of the integration between modules, PC-Sim may also be used to control PL-Sim simulated applications or, by means of PL-RIS module, the currently available laboratory equipment.
PC-Sim is capable of simulating the following PLCs:
The following is a short description of the elements which are shared by the three simulators. Specific details are included in the sub-sections where each simulator is described.
The Variable Status window displays the status and/or the value of all the PLC variables when the CPU is in STOP or RUN mode. Any input, output, memory, counter, timer variable status may be known by simply entering its code or symbol into the table. The table content will be real-time updated according to program processing results and field signal variations.
The Symbol Table window allows the programmer to identify proper matching between absolute operands and symbols. As soon as this matching is defined, the programmer will be able to use the latter rather than the former, thereby making the code more legible.
This window enables information regarding the current project to be retrieved or entered. Specific fields contain the project file name and the PC-Sim version which was used to implement it. The user may fill in the other fields by entering the name of the specific exercise, his name, etc.
