  1. Omron PLC Python communication

    Hello All,    I am college graduate student and I know little bit of cx-programmer for modifying existing program. I have master CJ2M CPU34 PLC connected with three CP1L PLC. All 4 PLC are connected via hub through Ethernet cable. I want to read/write some memory data to/from PLC through Python programming. As I am new to PLC and Python I have not much idea regarding omron PLC and python communication. So is it possible to connect python with master/slave PLCs directly? If yes then how can I communicate? I was trying with cpppo library to connect with PLC but I could not connect it.  I have attached the master PLC communication setup for the reference.    Any kind of lead/help is appreciated.    Thank you in advance.    -Yash

  11. Thought I'd share an experience I had earlier today working on a (limited memory) L61 Rockwell processor. I knew there was very little room left in the memory but needed to add some functionality and decided to give it a try anyway. I couldn't take the machine down to make a download so made a number of online edits, successfully accepting and finalizing after each edit. Got down to the last four edits which required zeroing a tag of type REAL. The instructions were on four separate rungs. Hoping to save time (and all previous edits were successful), I added the four MOV instructions (MOV 0 into TAG) and pressed the "finalize" button. I was caught quite off-guard when the process failed: insufficient memory. AAAAGGGGHHHH!!!! So close! I tried to remove some logic to free enough memory to add the required instructions. Nope. Rockwell was not going to negotiate. That left me in a position where I thought I was going to have to take the machine down and do, hopefully, a download that would push the processor memory to the limit but be accepted without any hiccups. But before I did that I had a fortuitous thought. I F1'd the MOV instruction and hoped to find a complete explanation of the instruction, including timing diagrams, execution time, memory requirements, etc. Oh wait - that's Siemens. GROAN. Curious and desperate, I replaced each MOV instruction in my edited code (I'd estimate somewhere around 20 instances or slightly more) with the CLR instruction - including the four additional instances I needed. And finalized the edits with bated breath. To my utter surprise (again!) the edits were finalized without overrunning the memory. A MOV instruction requires memory for both the source and destination. Since I was only clearing a memory I didn't need to reserve memory for the source. Using a CLR instruction implies "0" (zero) for the source but requires no memory for the source value. Hence the efficiency. Obviously, this story would have a different ending if I had been trying to move some value other than zero into a destination tag. I offer my experience as a lesson if you ever need to streamline some code to fit existing memory space. I also would like to know if there are any downsides to what I've done. Have i overlooked any potential pitfalls? Thanks in advance for the advice.
  12. Hello, I'm trying to use Mitsubishi GX Works 3 version 1 for the first time and get a 'memory is insufficient' error window when I try to open/start a new project or if I try to open a PLC project a co-worker made. I am using Windows 10/64-bit, company we purchased the software from says they are using it on windows 10 without issue. I get the error with no other programs running, have 6 GB RAM, and have 90% hard drive space available. I have monitored Task Manager while opening a file, RAM usage seems fine, and have tried opening with "Run as storminess".  I have tried uninstalling the program using the window "uninstall or change a program" - is the a different way to uninstall this program that will wipe it more completely? The install CD has Disk1, Disk2, Disk3(DocFX) sub folder , Support folders - I ran the .exe file from all 3. Does anyone have any suggestions? I am able to open an HMI project in GT works 3 without issue. I attached a screen shot of the error. Thanks so much!!

  14. FINS Communication with C++

    Hi, I'm having a little trouble connecting to a PLC from my program. I thought my previous post a few months ago fixed it, but apparently it did not do much. Here is my code: And here is the resulting reply from the PLC after converting it to hexadecimal So far, I've narrowed it down to the issue that my program is sending 64 instead of the 18 that was specified by the FINS command. I assume that the received error is due to the fact that the PLC did not receive the correct instructions from my program. The "End" is not sent by the PLC, it is a personal note for me to know where the received message ends. My goal is to simply receive signals from D00 to D68. I imagine that the received string should be in the form of: 00 C0 00 02 01 01 00 01 00 00 01 01 [Response Code] [Data] Can someone help point out where I can start looking for why my program is sending 64 instead of 18? I do think I am messing up something simple here, but I'm not sure where to start. EDIT: To clarify the models, I am connecting over Ethernet to an Omron CP1L-M40EDT with CP1W-CIF41 Thank you in advance!
  15. Hello everyone, As the title suggests I am trying to display on a GOT1000 the real time frequency that the inverter is running at. I have attached my CC-Link settings and the associated programming as well. I tried using the example program from Mitsubishi but I got lost. From my understanding I should be seeing the output frequency in W3C4 however, I am not receiving any data. Any help would be appreciated. 
  16. PLC programming languages are used to program the automation devices in the industrial field. The device connect through PLCs can perform certain tasks like moving products or sorting them. The 5 most popular PLC Programing languages nowadays are all part of International Electrotechnical Commission Section 61131-3 Standard. IEC Standard is a set of rules that standardize PLC languages. The PLC programming language can be divided into two section: text-based and graphical.   Text-based Languages: Instruction List (IL) Structured Text (ST) Graphical Languages: Ladder Logic Diagram (LLD) Sequential Function Charts (SFC) Function Block Diagram (FBD)   Five Popular PLC Programming Languages You Need to Know
  17. Folks, we have a set of Mitsubishi Q12PRHCPU (redundant) running effortless since many years. CPU-A as standby and CPU-B as Control. Recently we noticed BATT low alarm on CPU-B. So we arranged for a spare battery Q6BAT and started the procedure as per manual(attached procedure and flow chart). We did memory copy from Control to standby (as prescribed precaution) and did the Reset of Standby PLC CPU-A. Memory copy from B to A completed successfully 100%. But the BACKUP LED did not turn Green from Red & Error LED kept flickering on standby CPU-A. CPU-B remain in Control but backup LED turned RED. From system monitoring we found that there is a Error 6000 (FILE DIFF.) observed in One of the .QPG (program 00-MDBUS.QPG). We tried to reset it but were not successful. We are surprised that why does the program differs when it was copied from CPU-B to CPU-A using the memory copy. Still we did the VERIFY and found no difference between the programs in CPU-A & CPU-B.  Can anyone explain the cause of this issue and the solution. Please note that the CPU-B is still in control and plant is running. Backup LED on both CPU are red which means (redundancy loss) and error LED on standby CPU-A is flickering RED. There is no error in the CPU-A (Control) -we checked this using the GX Developer. Also attached here are the image of the error and error help. Thanks in advance.

  21. Siemens Field PG M3 - PLC Programming Rugged Laptop for Sale   Condition is Used   This is a Siemens Field PG for PLC Programming.   Purchased several years ago as part of an auction lot and has sat in my workshop since, I don't do much Siemens so this is up for sale - This is what I know about it :-   The machine has Windows 8.1 Pro 64 bit installed (Machine has Windows 7 Ultimate on the base but been upgraded at some point) 8GB ram installed It has a windows XP VM installed which runs the Siemens Programming software (Virtual Box) There is a folder on the desktop containing the original installation files, so would be easy to return back to the host machine if required. All software appears to be licensed (see pics)    Has Step 7 and Step 5 installed   Negatives - Missing the back flap & Battery not being recognised thus not taking on charge (I think this is a just BIOS update needed but not looked into it too much)   In very good overall condition, a few light marks but that's about it, still looks very good.   Comes with the original branded rucksack    This was a really expensive bit of kit in its day and still stands up as an excellent PLC programming machine   Open to sensible offers - I am located in the UK so worldwide postage will have to be calculated seperately   I have powered it up and it works well with no issues found, the PLC software all seems to work and appears fully licensed but as I am not the original owner and don't know the provenance of the machine or licenses this machine is sold with no returns or warranty provided.
