  1. cx programmer

    Hi everyone< i need some help with CX programmer i have written a programm as when i enter the Set value on HMI in D892 and press enter the Input 1100.01 energises and this executes Substract block (415) which sbstracts #6 fron D892 and saves it in D896. Them Comparison b;ock (300) compares D896 with #0 and as soon as D896 is equals to 0 the ouput flag W11.01 energises Now as u can see in the image below the value in D896 in substraction block and Comparison block are different and this is causing the output to energise at wron count . Why is there a difference In the D896 value?? 
  2. As the industry of plc and scada softwares continue to integrate more and more programming languages into their IDE, what is the most common language that should be learned by controls engineers (excluding Ladder Logic)?  I mainly use Python and VB for scripting but I am curious what languages other SCADA and PLC programming environments use. Should I be sticking to a specific language and learning it well or just know a little bit of them all? Let me know your thoughts!!
  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!

  6. Hello all,   I am working on a batch computer for a concrete mixer, and the computer that was running the plant before has stopped functioning. It was an old PC running MS DOS. The code is encrypted and replacing it is not a cost effective option.   I therefore am looking into using a PLC to control this batch plant. I have a setup that was in progress by another employee who no longer works for us, it is a CLICK PLC from Automation Direct, and it is supposed to be paired with a EA9 T8CL touch screen HMI from the same company. I would like some advice on just some basics, I would greatly appreciate some input.   I essentially only have one input, and that is an analog scale, 0-20mA input. I have digital outputs for sand, gravel, cement powder, and a water meter for adding water to the mixture. I have one final output, an additive for reducing the required water in the concrete.   What I would like to create is a program that when it is told to start, looks at the scale, and if the scale is less than say 100 pounds, opens sand until it hits 1700 pounds (as an example), then turns it off. Then it turns on the gravel and adds that for another 1700 (again for example, all these are variable), turning the gravel off after. Next the cement, and so on. I don’t need someone to write the program for me, but can someone point me in the right direction on using an analog input to turn digital outputs on and off? Again, your help would be greatly appreciated.   Thanks for taking the time to read this long post.
  7. Clamping PID in Compact Logix

    Hello all,  There are two pressure gauges in a line with a flow of water. The flow is controlled by the pumps which is controlled by the PID whose control variable is pressure gague -2 . In ideal condition the pressure gauge -2 remains at 55 psi and pressure gauge -1 stays at 82 PSI. But in the line if someone opens a manual valve then pressure gauge - 1 reads 100 psi because the pump is running as per pressure gauge 2 . Is is possible to clamp the PID so that pressure gauge 1 remains at 82 psi.    FYI: Pressure gauge 1 is right after the pumps and pressure gauge 2 is at the end of the line. 
  8. hello everyone, I using stepper 17HS2408, microstep driver, modul motion QD75D2, PLC QD3UDV,, i've been trying to use program Absolute in axis 2. When I trigger the command to run absolute program the current value is running but the stepper motor still not moving, is there any suggestion about this?
  9. GX works 2 software

    Hi guys    I am having trouble installing GX works 2 software. The software is fully legit and came with 2 license keys the first one I put on work laptop and second on my personal laptop. The install all goes fine but when i try open up GX  Works 2 I get this message from the attached image. I have plenty of room on my pc and even have other PLC from different manufacturers on it without issue but the GX Works is just giving me grief and I have tried to increase data on MY laptop and other windows fixes but still get this message when I try open it.  Has anyone else encountered this problem before or any ideas?   Cheers guys

  11. Quick Designer Software

    I am looking for a working copy of software that will work to modify screens on an old Quick Panel.  I believe the software is called Quick Designer. The old Panel I am trying to access is serial communication only. I have bought an interface cable from PLC Trainer.  I have a Windows 7  32 bit machine ready to go. Thanks, Scot
  12. EPLAN Help

    I am attempting to use EPLAN P8 (v.2.9) to import details from a 'holy grail' excel sheet of a cable list with terminal tags and numbers (source and target for each cable). To do this I began importing details in a trial and error fashion through the pre-planning menu to the pre-planning navigator. I have several questions. Question (1) Has anyone else tried to do this?  In the process of importing from the excel sheet I have not been able to successfully assign source and target for each cable object. It shows up on the synchronization dialog after I work through the field assignment but it disappears after import. ( I do not fully understand the proper structures, definitions, properties and levels to get what I want). I do understand if I import source and target terminals, and cable objects separately, then I can place on the detailed view and source and target are assigned then. Question (2) Does anyone know how to assign source and target to a cable object in pre-planning 'by import'?  (Reason being that the excel file is huge and manual assigning isn't feasible). On one of my attempted field assignment schemes I was able to have cable, source terminal, and target terminal, all on different levels (not actually assigned as source and target for the cable object btw.). However the result for source and target on the report (planning overview, form: f40_006) had all of the designations of the tree structure from the upper levels. For example, cable: HAC4401, source: HAC4401 X1:5, target: HAC4401 X1:5 TB1:5. (Where X1:5 is source terminal and TB1:5 is target terminal). Question (3) Does anyone know how to create a 'branch' or 'fork' in the tree structure in the preplanning navigator so that both source and target terminals (planning objects) are on the same level and so do not inherit each others details?  There's a bunch of info in reading the above I know, but if anyone can shed some light on this it would be much appreciated!!!! Thanks in advance,  MajorMac
  13. GX Works 3 (R04CPU) Device Memory

    Hello,  GX Works 3 / R04CPU. I'm using the Device Memory so that I can link the HMI to my PLC. I've set aside some memory, in this case D3260, to be used as a Real (32 bits data, Float single precision) to be set by the HMI (operator adjustable setting) and read from the PLC. I thought I'd move D3260 into a local label for readability/testing purposes, and it says I cannot move an Int into a Real - which is fair enough, but, how/where do I set D3260 as a real? Do I use some Functions to take D3260 + D3261 and make it to a real, or define the data area as a real somewhere...   Dumb question I know, I'm new to GX Works 3. Thanks very muchly

  15. Codesys

    Hello - I stumbled across some mention of Codesys and was curious if anyone here uses it. Pros/cons? prefer it over other programming software. Have it downloading currently (since you can download a free variation of the application) but it looks quite interesting. Also - what PLC hardware is programmed with it? Did not see that mentioned on their website when I was browsing through.

  18. Zm-71se

    Is there anyone, have this software? Coukd you help me
  19. So we have a PLC project coming up and its our first one and understand and can execute most of the sequence without issue.  The part that is getting me is how to handle the following efficiently using studio 5000 and panel view.   AHU has to be able to run test cycles User selectable up to 250 steps in a test cycle User selectable temperature setpoint for each step User selectable humidity setpoint for each step User selectable time duration for each step   I thought about using arrays but as i understand the allen-bradley plcs to change the array size you have to go offline and then back online so you could not change it dynamically.  Was considering doind this with reading the dataset from an excel document the user would edit. The other option for me is to have a static arrays size and then based on the number of steps the user select have the routine only execute x ammount of steps, which is done easy enough.  Big thing is after the code portion is lined out is there a way to dynamically change the hmi graphics to only display certain steps for the user to edit, maybe by using an array of bits that are on and off for visibility and then having a GUI object be shown or hidden based on that bit?

  21. Versamax IC200 Programming Cable

    Greetings Engineers  Does anyone have part numbers for programming cable to connect from a serial port on GE Versamax IC200CPU001 to programming laptop via USB?
  22. I have a 1996 Howa Vertical Machining Center running on a Mitsubishi M520AM control. 3 Axis with Jig Changer on the main control. ATC and 16-tool magazine on 2 each Model E/FCUA single-axis amplifier/controls with a DIO extension interface to main control . I lost parameters and User PLC program to the 2 Model E amplifier/controllers at  ATC and the Magazine servos. Dead batteries, and both units are back to defaults. Main Control and Operation Panel work. I can read the ladder and write to CPU ladder from the operator panel, and I have a paper copy of the main ladder and parameters. I have a working FCUA-CT200 pendant to communicate with the 2 Model E controls, but no way to program a new user ladder and upload it to the Model-E's. Anyone know where to find PLC software for 1996 vintage Mitsubishi CNC controls? I can probably make any kind of interface cable it would take to get from a PC to the control. the FCUA-CT200 teach pendant will let me enter parameters  via 'PLC I/F' but it won't let me program and read/write a User  PLC.
