  1. Hello. I am working on a pilot project building an automated RV park. Our goal is to have people sign in online, or in person at a kiosk. Make their reservation, payment, and get their confirmation e-mail. In that e-mail, will be a QR, or Bar Code, that when scanned at the gate opens the gate, and starts a light that flashes at the site they rented. Power will then be turned on at that site, and a timer in the process will begin, based off their rental time. Once their time has expired, the power at the site will be turned off, controlled by a PLC, and relays.  So I am looking for help in all directions. I have some leads on some plug-ins for Wordpress that offer reservations, and other plug-ins that do Bar code production. As far as the web part I have that covered. We can generate a custom barcode, or QR code based on individual rentals and those can be sent to customers. So what I need is someone to help point me in the right direction of equipment that can speak between the online Barcode process and the PLC to allow a process to begin when scanned. Based off their rental parameters their power is turned on or off. Perhaps a SQL query in some form? I haven't used it, but am aware of its capabilities, and this does seem like an application where it would be used. Is there anything that you have used that are tried and true? I know it's a strange request, just hoping someone bites. Thanks in advance for any ideas, I look forward to solving this puzzle, one piece at a time. 
  2. I am looking to open a number key pad on the display and when the operator is entering in his passcode. I would like to hide the numbers which he is entering as this is his master log in for the company network. Has anyone found away around this problem.
  3. To Whoever might read this: I am currently a journeymen electrician in CA with 12 years experience in the installation, Maintenance and design of commercial electrical systems. I have limited Industrial experience, but I know enough to get myself around without blowing myself up or the customer and their infrastructure. Recently, I have taken a few online courses on PLC programming using RSLogix Micro Lite. I realize this is very entry level stuff, but I thoroughly enjoy the process of forming ladder logic and problem solving and I believe my experience in electrical theory and installation has helped me understand the natural flow of this logic. My interest in this field goes back 10 years or so and I am just now getting around to learning the languages and logic behind the PLC's that I have built entire electrical infrastructures around. With that said, as a full time service electrician who just landed a job in the wastewater electrician/mechanic field, I am seeking opportunities to learn and grow in some form of internship or unpaid position as long as the workload is either remotely operable, or somewhere based out of the greater Sacramento, CA area.   I do not want to sound picky, but I am a young father with a full time career, newly married and a busy full time job schedule to keep up with. SO, I am definitely interested in any opportunity that will give me experience to add to my abilities as a programmer for future ventures. Thank you for your consideration!   MtHowe15 P.S. I am also TOTALLY up for any hints and tips as to what a good next step would be towards gaining experience!
  4. Hello! I am programming with FT view studio version 8. In the program, when I make numeric display, I can not input values for this tag I am using in the display. Then I decided to make 'invisible button' for enabling the input for this tag which is shown in the numeric display. This is okey for me, only if there is other ways to do this please tell me. Now when I have created this numeric display with input enabling -'group', I have a problem, how can I use security levels for this group, so that only logging in values can be set? I have found that there is security code selection for this in the screen displays, but not for the buttons.
