  1. Hey Guys!!!! I'm trying to use ASCII 8 bites in TWIDO PLC and on MOD BUS TCPIP it connected to WinCC , where I'm trying to read the ASCII in as a STRING char that to in 8bits. The problem I'm facing is that it is getting swapped like if I'm writing VA in PLC then on SCADA it is showing AV. In WinCC there is no setting for word swapping. Therefore Kindly help me for this in plc end

  4. I have this panel view 1000 plus with accounts enabled but customer forgot the app password. I have both the executable and source file. Can I retrieve the password from any of both files? Can accessing configuration mode help disabling security to enter new passwords? Having the files, what is the best way of retake control over this application?    I am not experienced on AB equipment, but have general experience on automation. I have access to Factory Talk View.
  5. 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.
  6. Hi all, I am trying to control and/or read values from Schneider Altivar12 VFDs. Via Modbus on a AB Micro850 PLC (using the Connected Components Workbench Software). There seems to be two ways to do this with the Micro850, either with messaging (using the msg_modbus instruction function block) or with the Modbus mapping feature. I have a list of the communication parameters (see attached fileATV12_Communication_parameters_BBV51917_1.4IE05b.xls ATV32 Communication parameters_a1.2ie03.xls) But I haven't had any experience with Modbus and I am not having any success. There is not very much documentation about how to do this, If anyone can help me who has done this or knows how to do it I would appreciate it.  
  7. Hello,I am trying to use ProWORX NXT to view the logic of my Modicon Quantum 534 controller online. When I try to go online with it, it always times out. I am using a TCP/IP connection and my PC is in the same subnet as the controller in question. I can ping the controller's IP address just fine and when I use ProWORX NXT's Net Scan function, it recognizes that there is an Ethernet connection at that IP address but doesn't recognize it as a Modicon controller.Weirdly enough, my PC can connect to another Modicon controller of the same type and in the same subnet just fine.Can anyone help me with this issue?
  8. Hi everyone, I would like change user password on HMI GTO via Vijeo script. I don't know which variables store the password. Anybody as an idea? Thank you in advance
  9.   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.

  11. Hello, I got a new work job to design a cycle tester for a mechanism to make sure will work for at least 5000 cycles open - close. I never made a pls program I start researching few days ago and seams to be very complicate to make it. I have a TM221C16R PLC from Schneider. please help me with some instructions. the cycle tester will have a start pushbutton, stop pushbutton, door open switch, one air cylinder with solenoid to push and pull and a counter. Thank you, Romica
  12. Hello everyone, I hope you are all doing very great, I'm new to Schneider PLCs and I have a project that I need to work on, so I will need your help with the following issues: *) How can one determine which Schneider PLC series is used if you only have a fuzzy picture of the PLC ?  *) I need to setup a historic of alarms, I have 13 PLCs, no connexion between them... I was thinking about creating a connexion between those PLCs and a database, so I need your help to determine a list of ALL the materials i will need (from cables to servers to a computer if necessary...) and some documentation on how that can be done... Thank you so much for helping me, Best regards

  13. GOT Password lost

    JanHrust posted a topic in Mitsubishi

    Hi guys I require some assistance. A client of ours has a A975GOT-TBD-CH GOT/HMI which is password protected. They have now lost the password and they need to get the program of the HMI ASAP. Can you guys please give me some pointers on how to either reset the password, without losing the program or by-passing it or even cracking it. Thanks!  
  14. I am having trouble loading the configuration into a Micro984-230. I lost an old M84-002 PLC. I have the program. I purchased a Micro994-230 replacement. I lost my cable, so I made a new one. The only software that I have still running is Updoc 4.30b. I tested out my cable and Updoc by connecting to a 984-381. Everything worked fine online and offline. The error I get during the configuration loading is communication error 13. I have no idea what that is. Perhaps I can't do configuration loading with Updoc. I have Modsoft Lite  working but I do not think that it works with this controller. It is for MIcro and Compact controllers. I may have modsoft and taylor kicking around but I do not know if they are installable or not. I hope I can find out if my config is improper, I have used the wrong controller setup file (used Micro984), or where iI can have the config loaded for me? I also do not know if this used controller is functioning correctly.
  15. Hello guys,   I'm new on this forum but I'm not new at PLC programming world. So far I had only experience with Siemens PLC controllers.    Now I have a relatively simple application in which I have 12 DI, 4 DO, 4 AI and 4 AO. The client insists that I use Schneider PLCs. I must admit that I had no previous experience  with these PLCs. Therefore I kindly ask for your help in choosing the appropriate PLC configuration.  The PLC must have RJ45 for connection to LAN network. I want to create a small HMI application and thinking of using IGSS software. There will be one simple PID controller to control temperature in one vessel.  Temperature is 4-20 mA signal. Via HMI application, operator can change setpoint for the temperature closed loop. Also, I need that other computer on the network have possibility to open HMI picture but only in read only mode. For this purpose, Web server would be ideal. I was thinking of using M258, but it seems to big controller for this number of I/Os. What can you suggest me regarding the PLC configuration and HMI software? Thank you!
  16. Hello there. I have connected wireless module (master) to Vijeo Citect 7.4 using RS-485 to USB converter. My slave modules are supplied power from gird/generator and the master module is supplies from a UPS.    I'm reading Modbus registers of slaves modules data via wireless master. Every time we have a power failure from grid, I get #BAD from all slave addresses. The generator kicks off within 30 sec. That is the slaves are off for 30 sec. Even after the slaves are powered on, SCADA does not poll data from it until I restart the SCADA.    My current MODBUS parameters are:   Inittype = 3, TimeOut = 3000, WatchTime = 10, Retry = 2. Could you please assist me on which parameters to change in .ini so that SCADA reads Modbus registers of slave for more than 30 sec.   I tried increasing TimeOut to 30000 but it couldn't solve the problem. I would appreciate if some one could help me out.   Thanak you in advance.

  21. I have a PLC, the PLC is TSXP573634 but I don't have a memory for it. I want to connect but I can't. The PLC is new. I used usb-rs232 and TSXPCX1031. When I want to connect I have this message:"This isn't a valid PLC Address, or PLC is busy, or media is off". I need for help!
  22. Hi, i'm new to this forum. I encounter some problem with the existing set up, where  Quantum Hot Stanby PLC (Master) can't read/write to 3rd party ESD PLC (Triconex). Quantum PLC need to read from ESD PLC where the configured IO for modbus is in bool(coil) instead of word (register). Any idea what i can do beside getting ESD PLC to change from boolean to word? thanks,
  23. Hello, I have received one CP1L PLC CPU for troubleshooting. It is password protected. Is there any way to solve it and backup the program? if no, is there any way to reset everything.?Regards,

  24. Ladder to Functional Block

  25. Hello, We have Modicon Momentum PLC and there is about 80 millions of Collision Errors (and growing cca 1.4 error per second) logged in Ethernet Statistics. In the manual they write only "This field should allways be 0". It is working for us though. We only have one problem that two machines on ADO 740 50 with ENT 110-01 stop simultaneously and irregularrly without any appearent reason. It is happening now for about 6 months, but I have calcluated that this collision errors accumulated over cca 2 years. My question is, what "Collision Errors" mean and could that by any chance make two particular machines on one ADO 740 50 module go off simultaneously?
