  1. So I did this simple Function Block, pretty simple, and yet it keeps giving me this error, after a bunch of failed combinations the error persists, without telling me whats wrong. And therefore won't even allow me to download the program to the PLC (CJ2M CPU31) or even simulate.   I heard it's a simple thing to fix but I really dont know how to, since I'm quite new to this. Here's the function block  itself in the picture and the programming inside it, although since it gives me no errors, i don't think that would be the problem
  2. Block Compare Instruction

    Is there a Block Compare Instruction like the one in Omron PLC for Mitsubishi PLC? If the Omron PLC is BCMP (68), then what is the name of the instruction on the Mitsubishi PLC? I tried to use BKCMP in the Mitsubishi PLC, but the way it works is not the same as the one in Omron PLC
  3. Hello. How can I get bit addressing of defined variable in function block? For example: - I define variable type DUINT with name Double_VarI_INT. - I want to get or set one bit out of it (its double word). - If I use Double_VarI_INT.0 I got error. Best regards.
  4. Hi, I've been working on a new software for a Weintek HMI model MT8071ie, which is controlling an Omron CP1E PLC. The computer is currently being used to simulate the HMI, connected to the PLC via USB. The connection between the computer and PLC has been flawless for the past few weeks I've had no trouble at all, but now all of a suden everytime I go to the online simulation I get the PLC No response that pops up. I've tried going through my settings several times to find an error somewhere, but nothing seems out of place. I also tried different cables, different PLC, I tried using backed up versions of my program that worked a few weeks ago with no success.  When I connect to the PLC using CX programmer it works everytime, so it doesn't seem to be a hardware issue. I'm starting to run out of ideas on where to check, if anyone has even a small idea on what my problem could be that would be great.  thank you!
  5. Hi, I'm working in so machine basic v1.5 and I'm wondering if it is possible to change the start time and stop time in a schedule block with a %MW. So is there a possibility to for example say %CH0.??? := %MW5 in an operation block? And is there a page where u can see al the possible codes. I already discovered that %TM0.P changes its preset but i don't find a list of al those possibility's.
  6. Hi All, I'm still quite new to Unity and Modicon PLCs. I have a PLC program running in simulation mode for development/test and I'd like to follow the logic inside a running block. I can't seem to just double click the function block while online to see it's 'inside' logic. Is there a way to inspect the inside of a running function block? How can I check and diagnose the logic a running function block? Thanks!
  7. Hi, can you help me how to make program indirect address for plc omron? I use PLC CP1E Thanks
  8. Can Anyone Come Up with the Screen Shots or a video link of procedure for Displaying Real Time Sinusoidal Waveforms From Satec MFM ON GE FANUC?? I have PACsystem RX3i via Serial Communications Module-IC695CMM002 
  9. can you help me? bring me some example to build function block program with Gx Works? I use Q02U CPU   thanks
  10. where are the FB libraries

    Hello, Im looking for the in built function blocks, but i cannot find it in the program files/ omron folder where the manual says (even with search for *.cxf), perhaps i dont have it installed, but where can i get them from? As i remember i downloaded cx-one from the official omron web page after login etc, so thats why i dont understand why am i missing the fb libraries What else place there is to find useful FB-s? Thanks!
  11. Unable to Monitor in GXworks2

    Hi! Anyone can help regarding this issue. I'm not able to monitor the Motor Block that I have created. there's no error either in the output screen but i'm thinking what is the cause of not running in the simulation which shows the Motor Folder RED  even it was compiled. thanks for the help!     Note: I'm new in mitsubishi.
  12. Function block self-made

    Hi, i want to make a function block which will contain a block GP.CPRTCL (for predefined comm protocol). GP.CPRTCL has an input "Un" who only receives constant (H,K). On input of my own function block i can set a constant variable, but inside block that variable isn't a constant anymore (GP.CPRTCL doesn't recognize a variable). Is there a way for receiving constant variable in GP.CPRTCL block ("Un") if it is in another block. Regards
  13. Beckhoff PLC Counter

    Hi everyone, I need some help with my PLC programming. I am currently using a twincat 2 software and a Beckhoff CX 8090. Basically, the gist of my program is to send and receive data and datalog the input data received from the sensors and timestamp the received data for every 1 second. I want to create a boot up counter where it will count the number of times my data logging program has restarted(if it did). This boot up counter serves as a health monitoring check to ensure that my program is running perfectly and thus, not restarting randomly when it shouldn't. I am more familiar with structured text so if you have a solution, kindly post it in structured text form. Your help would be greatly appreciated. Best regards, DeadPool
  14. PLC RESPONSE ERROR

    Hai, I have downloaded the program into the PLC, downloaded the program into the HMI VIA ethernet.When I turn on the HMI it's showing "PLC RESPONSE ERROR". I can write command to plc through HMI, But I can't read the signal from PLC, Does anyone know the meaning of this message or what I might be doing wrong or missing out?...CPU used:CP1L-EM40DT1-D, HMI used :NB7W-TW01B...PLC to HMI communication via ethernet... 
  15. Hello. I'm trying to use index addressing inside function block.  The command *D200 doesn't work. Is it necessary to use IR0, ID0,... inside function block? Thanks. Best regards
  16. There are a lot of instructions in function block that are missing the enable input that is present when programming in ladder logic, such as  ADD or MOV.  It seems to be very limiting. The only way around it that I know of is to write your own function block in ladder logic or statement list and use that. I seems rather limiting of a language if it relies on other languages for it to be usable. Does anyone know why the enable bit was left out in many function blocks when it is so useful in ladder logic? Pat
  17. I'm having trouble with some very basic programming using function blocks. Specifically Connect Components FB programming, but I think it is a general, common application. Using ladder logic, it is easy to set a value based on the status of a bit. If the bit is false, move a zero into the variable. If the bit is true, move and 88.0 into the value. This relies on the enable bit of the mov instruction in ladder logic. Many function block instructions do not have enable bits. How would I change the value of a variable based on the status of a bit using function block programming? A real world example: You have a two position selector switch. If it is turned to the left, the drive runs at 0 Hz. (off) if it is to the right, it runs at 88.0 Hz. Or if you have a 4 position selector and want to select between 4 speeds. This should be a simple task, right? I've called the tech connect support line a few times and sent them a few emails and they haven't been able to figure it out. This is such a basic task. Thanks, Pat
  18. Dear Experts!!!   Could you please provide me the sample of "QD75MS Module & MR-J3-B program with functional block"    As you can see the page no. 3  in the attached document  "KI-Doc_QD77MSXX_MR-J3-XXBS.Zip" sample is there but i am not able to find it anywhere.   Or if you have any otherone please share it.   Please help!!!

  19. Hi there I'm an embedded software engineer mostly programming C/C++ in Linux and have very little knowledge of the PLC environment.  Recently my attention was diverted towards integrating C/C++ (Linux software) into PLC and then presumably as a function block which is supported with something called PLCOpen. Is that right ? How is multithread support in PLC in general ? and/or with the these function blocks or what ever might become instead when integrating/porting C/C++ code into PLC.  The current situation is purely embedded Linux environment with open-source 3rd party userland that our code relies heavily on. How feasible is to port such environment over to PLC (given that the system supports it) ? I've been looking into B&R Automation Studio 4 and having a hard time to establish concrete feeling on how difficult/easy it is to port the code.  Hope anyone can give me a slight insight into this.  Kind regards Einar

  22. Siemens S7-1500 and SICK

    Hello all, Let me start by saying that although I have been working with PLCs for 20+ years I am very (as in brand) new to the Siemens world (my wheelhouse is AB). That being said I have a Siemens S7-1500 (1511 specifically) CPU with a couple of SICK multi-turn Profi-Net encoders (AFM60A-S4NB018x12) that I need to talk to. - I am using TIA v13 with all of the updates. - I have the GSD file from SICK for the encoder. - I have no clue what I am doing - I can see the encoder values update in the watch table as I move the encoder. All fine and dandy so far... Here's where the white flag is going up.... - I am of the belief that there are existing function blocks out there 'somewhere' that can read and write to the base parameters. I have contacted our local rep who deferred me to SICK. I have emailed and left messages with them and have not gotten a return anything thus far. Here's our application... We are attaching each encoder to its own rotary gear mechanism. The rotary will need to turn in the CW direction approximately 400 degrees then return to its start point by rotating in the CCW direction by the same amount. If/When production/maintenance needs to 'rehome' the assembly, the expectation is that they 'pin' the drive in a known location then a bit would be set within the CPU that would assign a specific value to the encoder's actual position. In the SICK manual (8015078/YIX6/2015-01-16) on page 31 (section 3.6.3) there is reference to Preset control. This is what I believe we need to perform the aforementioned function. Does anyone have any examples that they could share on how to read/write to these encoders by use of a Function Block or other? Relatively desperate for help at this point. Can post test code if need be. Thank you in advance, TLAF
  23. Let me set the scene. I am inside my function block. I would like move an internal integer into an integer that belongs to my program symbol table. I would like to do it inside the function block, so that the function block is self contained. i.e. it does not need any extra inputs/outputs in the function block call. Is this possible? If I was writing this in Object Oriented code, I would just write this within my method: myGlobalVariable = myLocalInteger; and that would be that...
  24. Hi all, While upgrading HMI from PanelBuilder32 to FactoryTalk View I encounter a problem using I/O to interface with a PanelView Plus. The communication is defined in RSLogix 5 program as Rack 3 group 2 Size 3/4, range 32-37. PLC communication with the panel is not changed, but buttons in old PanelView using I:34 and I:35 work, in the new PV+ they don't, all bits remain zero. Block transfers Read and Write are all sending data to rack 3 group 2 module 0. While testing I noticed O:32 is used as status bits by the Block Transfers - maybe inputs I:34 and I:35 are also used for somethings similar by a new PanelView Plus? Thanks!
