ROM Cyber-SGS IV Style (If you have better suggestion, don’t be shy to share with us ) ) (Space between chipboard and dash I fill with foam) Micro USB Male to Female Adapter Cable Extension Angle Connector Cord Links are only for example.īlock Magnets (Neodymium Block Magnets 25x8x2 mm N52)Ĭircle magnets (18mm x 2mm Neodymium Magnets)Ĭable with fuse (Add A Circuit Fuse Tap Piggy-Back MICRO) I was in seventh heaven when I found this cable:)) I find a lot of stuff at home or bought it in local store. When I touch the screen, brightnes go to 100% (or what you set in macrodroid). So if I want to change the song, I just touch the screen and press next song. Screen ON During player run, screen is ON and dimmed. With this function I prevent if I forget to stop player when leave a car:)Ģ. When I arrived at work I just turn off car, and task will stop the music over a minute. So when I seat in car, just run task and player start automaticly. Timer for music player: I am driving to my job around 30 minutes into one way. Just in case, because you never know I added micro usb cable for charging. I spent many hours to find player, tasker (macrodroid) app, made tasks and tested everything. My goal was to improvise with materials I was found at home, don’t “touching” dashboard and use phone without battery. I decided for this installation because I'm a very big freak of hidden cables and simple usage. When writing interlocks in this way debugging become really easy, because you can just navigate with 1 or 2 clicks of the mouse to the cause of interlock without having to analize a lot of logic.I will show you how I installed phone in dash of Subaru Legacy/Outback 2010-2013, without "touching" a dash.Įverything is removable and you can turn back into original in a couple of minutes. Same as alarms, interlocks must be above the segment that declares the output coil condition and the interlock bit should include every condition that stops the motor.Ī common strategy that peoples uses when outputs grows in number is to have a block dedicated to interlocks that comes exactly before the block dedicated to output, like this: I usually write outputs logic and interlocks in this way: To extend the digital clock with support for alarms, we need to add a few crucial pieces of functionality to the code from last week: We need to have a way for people to set and edit alarms. Once you detected the fault conditions for your plant, you should use alarms and other conditions inside interlocks to avoid dangerous operations. This is just a basic explanation, but you can find a more detailed explanation about fault logic here: Writing interlocked equipment in ladder logic: This bits triggers all the alarms-screens and alerts on HMI and scada.Alarms starts from number 1 and continues, so it’s no use to have an offset among alarms and bits.The first bit of the word alarm has been chosen as “no active alarms” because usually: The last part is a recap of all alarms, really useful while debuggin because you can notice instantly what’s going on just by watching 1 segment. This because even if you reset all the alarms pushing the reset button, if one fault condition is active, the alarm will be setted again few segments later, resulting in a still active alarm at the end of the program. When writing alarms in this way the first segment must be always the reset block. This is a basic sample on how i write an alarm block: When i write alarms and interlocks i always use the same structure, that consists in many words where every bit corresponds to an alarm this structure is almost a standard for many operators panel and has many good points but some drawbacks too (a drawback is that you can analize block of alarms comparing and masking entire words, that can be cheaper to write, but harder to understand when reading or debugging). Interlocked equipment, like motors or valves, is an equipment that has a protection circuit (real or logic) that interdicts the activation of the equipment if at least one danger condition is met. What is an AlarmĪn alarm is a condition of non-safe state of the machine.ĭepending on the impact on the process, it can be:Īn alarm can be connected to an input sensor, but it’s never the sensor itself alarms are generally stored in words (16-bits registers) and displayed in the HMI, as well as used in the program as conditions to grant the safeness of the process. While analizing the process that you have to automate you always have many conditions to respect for the safeness of the equipments, of the operators and of the process itself.
