  1. Hi cHud, thank You for Your help. It is a program for machinery self testing. Each message relates to certain step number and informs operator what to do. If it works with 255 steps I can divide the process. But, may be, it is possible assign the text value with a script?
  2. Hi, I am new to Vijeo. The task is to show different messages on HMI screen (I use Vijeo designer V6.2.5 and Magelis HMIG3U).  A new string variable "ToDoTxt" was created as an Array with dimension 2048. A StringDisplay was put on the screen and ToDoTxt[0] was chosen. How can I show other 2047 values, which depend on value of another integer variable "StepNumber"?
  3. Thank You Garry. I used Modbus TCP before. Where in the Unity Pro do I have to set something to choose Modbus TCP or Ethernet IP? Is it in Communication>Networks>Add Network..?
  4. Hi Garry, thank You for the answer. How would You recommend to configure communication between M580 and  HMIG3U ? What is the easiest way? regards, Wal
  5. What is the benefit of using Structured programming?

    I am not sure, that this is specific to Mitsubishi. Does anybody compared other  PLC performance running structured versus traditional? I don't remember such reports. Generally, the idea of structured programming is good. But, in reality, the big PLC manufacturers have no interest in investing money for improving their tools for structured programming. Most programmers use ladder anyway, because it is simple and works fine. Why should managers hire engineers and spend extra money? Will income increase? I compared Mitsubishi FX and found that the ladder program perform better. It is possible that with Mitsubishi Q or L result will be different. It depends on compiler.  Generally, the problem is that the hardware is not standardized. The automation market is badly segmented and investment in the software standardization does not make profit.  
  6. Hi, I am new in Unity Pro and trying to make connection between PLC (Modicon M580) and HMI (Magelis HMIG3U) over Ethernet cable. Question:  What is meaning of 0.0 : EIO : CommHeadDIOL2 (look the picture attached)? Which IP address does it define and what for?
  7. What is the benefit of using Structured programming?

    Dear Inntele, thank You for the response. Please, explain, what everything? Do You mean, if structured programming would be chosen, the PLC will run quicker and demand less resources?
  8. What is the benefit of using Structured programming?

    Dear colleagues, thank You for the responses to this topic. More than 9 months left and I want to add more.  1. I never met situations where Structured programming in comparison with ladder, potentially could make benefit. 2. In cases when I used the Structured programming result was negative. Instead of reducing programming time, there was increasing, PLC run slower and demanded more memory. You, may,  have to choose a stronger PLC for Your task. 3. Every new compilation can change the local variables address.You need to clear PLC memory every time before download. It's most annoying.  After that all registers used have to be set again to their values. Conclusion: Use ladder.  For discussion: If we avoid using local variables in the Structured project (make all global), is it still necessary to clear PLC memory before download?
  9. Dear colleagues, several years I programmed Mitsubishi FX using ladder (Simple project in GX Works2). A couple a year ago started to use Structured programming. Sometimes I ask myself: "What is this all headache for?". There is a lot of function blocks, but many of them do not work. Why they are being kept? Periodically, You get some strange compilation errors, You never heard before. Simple task: divide something by something is not as simple by structured project. Now You have to clear PLC memory, each time, before downloading program, because  automatic assignment can do anything. Two projects for FX3u were compared, the same task, one made with ladder, another with structured programming. The last one run about 40% slower and demanded more PLC memory. In theory, the structured programming should save developing time. But, does it really happen?  One Mitsubishi PLC programming trainer told me, that in Japan they don't use the structured. Is it true? What is Your opinion?
  10. GT Designer3 Script Problem

    Thank You kaare_t . Can You advice, please, how to create a csv file with HMI tag's values on an USB stick inserted into GOT2000? Is anywhere examples available?  
  11. Communication to plc using phone

    Hi kaare_t, thank You for the suggestion. If I have FX3u*+FX3U-ENET-P502 (can it be FX3U-ENET as well?) and network cable,  what else do I need? Which router can be used? Which software tools do I need to write an application for a smartphone (with Android, Windows Phone or Apple OS)?
  12. Communication to plc using phone

    Read the manual. They offer tool which would allow to control Mitsubishi PLC by using Android tablets or smartphones and wireless router. The PLC is to be connected to a router with an Ethernet cable. From FX series FX5 can be used only. Q-series PLC can be used as well, but demand the newest Ethernet units ( '15042' and later). Is "MX Component for Android" available in Europe?
  13. Communication to plc using phone

    Thank You Gambit. Sorry, I found the manual "MX Component for Android" in English. Need some time for reading. About 2. GT25-WLAN unit: Did You do it or read a report about successful try without GT25-WLAN with a wireless router? Do You know, how to do it?  
  14. Communication to plc using phone

    Thank You Gambit. As I understood, to try wireless control with GOT2000 HMI we need: 1. GT25 or GT 27 HMI (not GT23) 2. GT25-WLAN unit. 3. License ( 1 for each GOT unit). 4. GT Works3 V1.144A . This set is not something, we can get easily. Don't know how much does it cost, but doubt that it would be acceptable for home automation. MX Component for Android is very attractive solution. Unfortunately, the links You provided point to the sites using Japanize language. Can You, please, help more?
  15. Communication to plc using phone

    Thank You Gambit. The  Sibochina offer Android tablets with embedded RS485 terminal. It is not a phone, but the possibility to use MX Component there is exciting anyway. Loaded the operating manual of Mitsubishi MX Component V4 (is it the latest?), but haven't found any word "Android" there. The GT25 option is, obviously, more expensive, but interesting as well. Can You give more details about both options, please?
