  1. GX Works3 Projectlib Locked

    Sorry, I will try to make myself more clear. I would like to access the ST code of the modules located in the projectlib to change some stuff and see what the signals I want to use depend on and the rest of the places that they are used. That I cannot do. What I am trying to do though is to use some kind of delay logic such as a counter in order change the behaviour of the alarm handling.  I want the alarm output (the output of the OR circuit) to be generated after I have received 3 alarm signals internally (that for every input signal to the OR circuit). I also want this value to be changeable from my HMI. In the picture with the OR circuits the inputs are each unit's alarm signal, that is where I am trying to implement this delay/counting logic. That's basically all I want to do at the current time.  I hope that you will understand me better now.

    Hi, I do not know if it is password protected. I have attached some pictures.  What I want to do is to connect the D108 signal to the alarm function in a way so that it will generate an alarm after every 3 faild attempts (alarm signals).  What I tried doing was to connect a counter before the OR circuit and then just let the alarm signal enter the OR after 3 signals.  I am kinda new in plcs, have mostly coded on C and that is why I wanted to use the library so that I could write something in ST instead.  Any help is welcomed and if is possible to acces the source code, that would be great :) Thanks in advance
  3. GX Works3 Projectlib Locked

    Hello, I have a problem that I need to solve in a PLC program has it's projectlib locked.  I work for a company that contracted a PLC programmer before my time to program their new version of their control cabinets. The company did not write any specific contract with the contractor and just relied on his work. The guy later delevered a buggy software that is kind of functional (the bugs came up at the commissioning after the guy was paid and now he refuses to help or to provide more consultations). I have as a task to freshen this up and make it work without bugs, the problem is that the Projectlib is locked and I cannot access the source code.  The only thing that I can changes that I can make to the code is to put some logical circuits between the I/O of the already existing function blocks, which solved some problems, but not all and it keeps one of the most important ones as well. Anyways, that's my story, so now my question is, is there and possible way of unlocking the projectlib? Any feedback would be highly appreciated. Thanks in advace!
