  1. Hi   First post in this forum - hope I'm not duplicating topics..... I've had prior experience with Siemens S7 Tags for I/O allocation - how is it done for the M340/Unity setup please ie how do you assign a physical address (say %I.0.1.5) to an input in the program? I imagine it is somewhere in the 'Configuration' section where I have defined all the modules?? I find the standard help quite hard to follow and find what I'm looking for - anyone have any better documentation. Also I am feeding a quadrature encoder output into a high speed counter module - any tips/examples of suitable program structure to use? Thanks for listening.... Andy  
  2. I am having issues with M340 IO scanning. I have the NOE card next to the CPU which is a 2020 item. I have set the Network for the CPU as 192.168.0.5 and the NOE card as 192.168.0.12. To the NOE card I have connected a Deep Sea Electronics 8610 MkII generator controller which has configurable modbus pages. Its IP is 192.168.0.3. I have set the IO scan tab of the NOE to read the device at 192.168.0.3 starting at remote address 442497 (Page 166 of the DSE, 166*256). for 80 registers and to store them in PLC at %MW300 onward. When compiled this read works perfectly with values being loaded. The problem comes when I try a second read from the same device. This time Page 167 (167*256) at address 442753 which is sent to local PLC %MW380 onward. Now when I compile the code the first page is read OK as prior but the second read shows a "Faulty/Absent" on teh IO scanner debug page and no values are read. If I change the first entry to scan page 167 with page 166 deleted, again all is OK. It seams I am unable to make more than one read of the DSE product. I have spoke with DSE whom state the device can have multi reads from multiple masters and they have proved multiple reads from the same and different devices. I am now at a loss as to what to try next. I hope somebody can provide some insight. I also tryed doing teh second read with a standard READ_VAR command with teh same result. Just wondering if its a NOE thing or a set up thing I have missed.
  3. when i try to upload a code to m340 it give me this message  "This isn't a valid PLC Address, or PLC is busy , or media is off." whatever i use usb or tcp/ip port, it don't always give me the message but most of the time it does and i have to unplug and replug the cable many time until it upload the code, i am sure it's not a cable problem what can it be?
  4. 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!
  5. Hello everyone, I have difficulty to setting up the GSM configuration or the serial RTU configuration so that I allow you with another RTU. I use Schneider CPU Modicon M340 in conjunction with RTU communication NOR0200H and a Modem Schneider SR02 MOD02. This is the first time I'm working on this kind of project, want to help me, I'm stuck and I need a solution, thank you for your time.  
  6. I can not figure out how to perform Io Scanning without using NOE Module  Is it by using Read_Var and Write_Var ?  and if it is , How . Any links can help ?
  7. Hi guys, I have tried almost everything and ran out of option on how can I successfully connect modicon m34020 processor using mini USB with unity pro, I am working in Windows 10 and selected everything possibly correct I can, like setting address to USB, and "SYS" in Set parameters, I have USBplc driver installed and it shows, "disconnected" and local and remote id emptly fields. In my device manager, I can see a question mark on the processor driver "BMX CPU" and when I try to update/upgrade/fix it it simply goes to nothing. While the Unity Pro shows the error "this isn't the right address or the plc is too busy or off". Please advise, if i am missing something. thanks in advance.
  8.   Hi All.I hope you are all doing excellent and also, hope you can help me.Today I contact you as I am having some issue when programming a PLC.I need to create a piece of software that:1) Can control a random number of machines at any given time.2) Each machine is a slave 3) They are exactly the same, do exactly the same thing.--------------So far I have managed to create a piece of code that allows me to control a fixed number of machines but things get complicated when one job does not need 10 machines but 20 and the next one needs 15, and the next need 5 and so on.I have thought to use arrays to do this job but this is an area I have not touched at all and I would like to ask for your advice in this area.I hope everything is understood.Thank you very much for your help in advance.
  9. Hi guys, I'm in the middle of a little university project, I'm attempting to implement a control system purely based on artificial intelligence. A neural network will be used to map the characteristics of a power plant. A fuzzy logic controller will be used instead of the conventional PID and finally a genetic algorithm will be used to tune the controller while the system is online. This is all simulated of course. Each of those AI's will be developed in Matlab. Only problem with that is, is it outputs the code in C or C++ (From memory). I would have to convert this to structured text (Based on Pascal). So to circumvent this problem I thought I would just directly interface matlab to the PLC (Schneiders M340).  My idea being, all the calculations are done in matlab which are then sent back to the PLC. However this presents me with a new problem of how I would be able to interface matlab to the PLC. If anyone has experience with this sort of connectivity, any advice would be greatly appreciated. Thank you in advance, Luchek
  10. Hello everyone, I'm having some trouble to setup the GSM configuration so I can receive alarms on my cell phone I'm using Schneider CPU Modicon M340 in association with a communication RTU NOR0200H and a Schneider Modem SR02 MOD02 this is the first time that I work on this kind of project, would you please help me I'm kind of blocked and I need a solution asap thank you for your time
  11. hi everybody ; 1-i want to connect m340 with hmi (gto) via ethernet and i want to set adress of the (m340) in the vijeo designer but i don't know which protocol of these i can use and how to set the adresses does anyone has a pictured pdf for which protocol to choose 2- do i need to download (run time installer) to the target(hmi) before i download to it or it is already downloaded to the gto automatically .
  12. Dear All. I need an Instructor to teach me Unity Pro XL Programming used in M340. I am willing to pay whatever you ask for it. It can also be off line by Emails or whatever your Schedule works best. I need a coach trough out my Start and competition of the project. Thanks in advance.
  13. I have a rack with PLC and Ethernet card and I/O cards . I have an other rack with out PLC , Just I/O cards and Ethernet . I must be able to read the data from other rack through ethernet . How to config those external card into my plc . M340 Ethernet Remote I/O Any help or link or pdf is appreciated in advanced. Thanks
  14. I have 3 racks . 15 Digital input. Please see the attachment and let me know Do you think this is the good idea to do them for All the Inputs and outputs.? what are the limitation regarding %MW? Please excuse my English. Thanks.
  15. Hi Im new here! Please let me know What cable do you use to program a M340 ? -1- a mini USB ? -2- Ethernet ? -3-RS485? any one can give me a sample test program to test M340? just a dummy simple program to start from there. I appreciate it in advance.
