At each variable can be associated a mnemonic. It is then possible to use the mnemonic or variable completely transparently in programs. To associate the variable Switch to the input %I0, the variables RedLight and GreenLight to the outputs %Q0 and %Q1 respectively, it is necessary to write: %I0 Switch %Q0 RedLight %Q1 GreenLight
PLC 3000 has 2 system bits: %S1: for the initialization and setting of timers and counters, %S2: for the initialization of the memory bits. These system bits correspond to Rising Edges correlated to the RUN of the Code and the Reset of the scale models.
Functionalities of PLC3000 are accessible from the exercise catalog, with a login and password. The user is granted access to an index of themes and exercises presenting a sequence in the learning of Automation and Grafcets implementation according to the IEC 61131 standard. Access to each exercise is very easy via navigation between the different […]
PLC3000 is an intuitive tool for coding and simulating Programmable Logic Controllers (PLCs) with various interactive scale models. It has the advantage, from the user’s point of view, of using only one page on a web browser. From this web page, the user has access to the exercise topics, to the visualization of the educational […]
