  Hi Tobby, why do you need such a function? There is the Sleep() function in REXLANG, but it is highly recommended not to use it. You should write your REXLANG code so that it executes as fast as possible. For details see REXLANG documentation. Best regards, Jaroslav

  Hi Karel, the COUNT function block is definitely a good choice, however you should be aware of project timing because of quite high input frequency. I recommend you to have a look at example "0120-23 Frequency of Pulses". Change the project timing so the "tick" parameter is 0.001 s (within the EXEC function block) and "ntick0" according to your needs. It means that Quick Task will be executed every 1 ms and task on Level0 every 0.001*ntick0 [s]. Note that the period of 1ms is quite challenging for Raspberry Pi. I would recommend to use Raspberry Pi 3B+ and watch diagnostics. Hope it helps. Regards, Tomas

  Thanks Jaroslav, So using a not block would be the preferred way for making it work for cooling. Cheers Mike

  Hi Sid, thank you for your question. Custom made solution is far beyond our "free of charge" support. However here are some function blocks which might help you achieve your goal: TIMER_ - Multipurpose timer BINS – Controlled binary sequence generator EDGE_ - Falling/rising edge detection in a binary signal If there is anything unclear, let us know. Regards, Tomas

  Hi Mike, not sure if I understand correctly what is the issue. Can you provide more information? Can you share screenshot of the project part and a sketch of desired behaviour? Is the issue about setting binary inputs sequentially which produces more logs to be written? Thanks. Cheers, Tomas

  Hi Phil, let me answer your questions: ad 1) Yes, in order to count time connect CNI=1 to "ti" input as you proposed. ad 2) Correct, "Y" should contain time. ad 3) Exactly. It also assumes that your boolean signal from pushbutton is connected to input "u". For more details about the INTE function block see docs: https://www.rexygen.com/doc/ENGLISH/MANUALS/BRef/INTE.html#x81-800005 Cheers, Tomas

  Ok, thanks Jaroslav. I'll use a combination of the ALB and what I currently have to achieve both. This way I'll get both live HMI and logged alarms. Cheers Mike

  Hi Mike, I see. In that case the simplest approach is to use the TSE block (three state element), which moreorless combines two comparators with hysteresis. Kind regards Jaroslav

  Hi George, if I understand correctly you are trying to write (change) parameter inside function block (TIMER_:pt) from the running project, right? Have a look at function block called SETP*: https://www.rexygen.com/doc/PDF/ENGLISH/BRef_ENG.pdf#page=307 This group of blocks enables you to remotely change parameters (Real, Integer, Bool) of function blocks. If this is not answering your question, please, let me know Regards, Tomas

  Hi Kris, you are right, it is necessary to force the valve to fully closed position once in a while. The SRTF function block is not the best one for your needs. I'd go for the ATMT state machine or simply use an ISSW switch to send logic 1 to the DN (CLOSE) input. Jaroslav

  Hi, this is possible. Put the PROJECT block into your project main file (the one with EXEC block) and tick the SourcesOnTarget parameter. Hope this helps, let me know. Jaroslav

  Hi Emmanuel, you are right, I can replicate the problem. I'll forward this to our developers. Thanks for reporting the issue and the workaround! Best regards Jaroslav
