  1. I connected between Altivar 71 VSD drive and Modicon M340 PLC through MODBUS RTU RS485 and the communication is ok, now i want write  a command word using Write_var function to control the VSD but I find very confusing. first : it's written in cataloug that bits from 0 to 15 can be assigned to commands , is that done from HMI? i  can't find anywhere on HMI. second : in the function (both read and write) obj element can be int or bool bit but the EMIS element  in 'write_var' function (data going to VSD registers) only accepted if it's array of int not bool so i can't trigger the bits i want !! third : like the picture the VSD showing it's in NST mode and it says that it won't start until hex value of 6 written to command word but the catalogue says that only bit 0 is assigned(to forword command) and other 15 bits are free for user to assign and 6 in hex (0110) bit 1 and bit 2 still not assigned to any thing  !! i hope anyone could help 
  2. Vijeo Citect - write to tag - error

    Hi everyone.  In Vijeo Citect SCADA I created some tags and I try to write to a bit device of MELSEQ Q PLC. But I get this error : Cicode General software error. Note: I can read from PLC.
  3. Walt Boyes reports that Dick Morley, the father of the PLC died on October 17th. Wikipedia has been updated and summarizes Dick's contribution to the automation world: "Richard (Dick) Morley (died October 17, 2017) was considered the "father" of the programmable logic controller (PLC) since he was involved with the production of the first PLC for General Motors, the Modicon, at Bedford and Associates in 1968. The Modicon brand of PLC is now owned by Schneider Electric. The PLC has been recognized as a significant advancement in the practice of automation, and has an important influence on manufacturing industry." An article gives some history of the process Dick went through in the early days
  4. hi guys.  I am getting a server problem while communicating pc & scada . is there any solution to rectify it? or problem is in license? thanks in advance
  5. i'm working with vijeo designer and i have a problem with popup windows. I'm trying to make a popup window appear with a variable. A bool to be exact. I want that a popup window appears when the bool becomes 1. But so far i haven't found a way to do that. Can someone help how I could do that? It's the meaning that that bool becomes 1 when there is an error and that the popup window appears then to let the user know there is an error. Or does annyone have a better idea?
  6. Hi everyone, I'm a newbie in the ladder logic programming languages. For my thesis project I've to develop a scenario but I'm stuck with the creation of a socket connection from the Modicon M340 PLC to a server for transfer continuous data given from sensors or similar. Does anyone have a sample program that could have such a functionality so that I can change it based on my needs? Thanks in advice for any further reply!

  9. Hi ALL, We have a Modicon TSX Premium PLC which has fault and cannot run I am searching for the software to program the Processor and how to talk to it Thank you Chris
  10. Hello. Recently I created two projects which I later connected with INCLUDE property. Let's say we have Project_1 and Project_2. In Project_1 I include Project_2. Everything works except Trend Groups. The only trend group which is working is the one in Project_1. I know I can copy Trend Group definition to Project_1 but then these two projects are not independent anymore. Did someone come to some kind of solution? Thanks
  11. Hi all, I am working at a company that has a paint booth that is rather outdated. It has 10 robots in the booth and the safety circuit for each robot is controlled by a Modicon Nano TSX PLC. I have managed to successfully download the programs with the PL7-07 software (managed to do it on a laptop with window XP). We have some back up programs that were taken roughly 4 years ago and I would like to load them both up on the software and compare them. Is this function possible and if so how do I do it?   Thanks  Shane
  12. Our site currently runs Citect 7.4 SP2. We have a redundant server set up, with about 5 - 6 Clients and growing to 8 clients this year.  I'm new to the industry, been in it for about 3 years but I'm getting the feeling Citect may not be as good of a solution for us as something like Intouch looks to be. We are a Batch Process, Food Manufacturing Site. Citect came about years ago by a local sparky installing it as being used as a stand alone, small, simple, <500 point, HMI and Alarm viewer for a piece of original plant which has now grown to multiple plants (Same site different process areas) and 5000 points, which will need upgrading soon. I haven't used InTouch myself, but most other integrator's I come across are always like "Oh, why do you use Citect?", also almost all local integrator's use InTouch, which looks like it has much better add-on packages, support and graphics. We're not there yet, but we're continually moving to try and become a full S88 plant and I'm just starting to think do we jump ship now? I see Schneider have acquired Invensys, as we have System Platform to use the Historian with our Citect System. Just interested to see what people here, particularly if you're familiar with both, thought about the two? Citect is ok, but InTouch looks like a much better solution.
  13. 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 ?
  14. Hello, We have this SCADA system Vijeo Citect 7.2 running in Windows 7. Primarily used as generator's alarm history & monitoring. PLC: OMRON C200HG All communications are good but DIGITAL data (alarms, bustie) from OMRON is not updating in real-time. (Need to restart the Vijeo Citect to make it work).  While BCD & LONGBCD datatypes (voltage, speed current) are working good and showing real-time *OFSVIJEO: INT datatypes are also working good. Protocol UNITY         MODNET30 OMRON      OMRON OFSVIJEO  MODCELL  
  15. We are communicating FX3GE PLC with Vijeo Citect SCADA. We tried various protocols such as MelsecNET, MelsecFX2N, Melsec1, etc. If you know how please help.
  16. ASCII Code 8 Byte In Twido

    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
  17. Hi, everyone! I need to connect Modicon M238 (TM238LFDC24DT) with Magelis HMIGXO3501. I was not able to find any programming guide for this family of HMI's, so I kindly ask for a link, or maybe a PDF copy, For now, my problem is that I have SoMachine v4.1 with Vijeo Designer 6.2 installed, and the GXO family is not displayed in the configuration catalog.
  18. 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.
  19. Citect: Displaying IO device comm. Error

    Hi guys, In my current project, I have a number of energy meters (128) communicating on Modnet (TCPIP) with Citect as different IO devices. I have a screen, where I wish to display the communication status of each IO device. If there is an error communicating with a particular I need to associate a tag for displaying the same. Can someone guide me how to accomplish this.   Thanks for looking in.
  20. 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?
  21. 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
  22. Hello, I am responsible for implementation of Vijeo Citect 7.4 SCADA in my company. I want to connect to Beckhoff PLCs by using Twincat OPC Server. I can control and observe the variables through OPC Control tool, but when I add the device and variables to my Citect aplication, they are always equal zero. I cannot also force through Citect to change the value. I don't know where the problem lies. If you need additional information, please ask me. I will provide you with all the data I have. Thank you in advance. beckhoff_opc.bmp

  25. in Citect i use the following function to associate various Tags with the next popup window, in the previous versions the tags passed to the trend fine since upgrading to 7.4 the trend pens dont display but all the values display fine.  FUNCTION // function AssPIDPopup // Expand a full set of PID tags and open // the PID block supergenie AssPIDPopUp(STRING sSGenie,STRING sBasePIDTag)     AssVarTags(-2,0,sBasePIDTag + "_PV");      AssVarTags(-2,1,sBasePIDTag + "_SP");      AssVarTags(-2,2,sBasePIDTag + "_OP");      AssVarTags(-2,3,sBasePIDTag + "_MAN");      // Now the tags for the PID tuning SG     AssVarTags(-2,4,sBasePIDTag + "_KP");      AssVarTags(-2,5,sBasePIDTag + "_KI");      AssVarTags(-2,6,sBasePIDTag + "_KD");      AssPopUp(sSGenie);      END I added a button to run the following code FUNCTION Loadtrend()     TrnSetPen(19, 1,  AssInfoEx(1,0));     TrnSetPen(19, 2,  AssInfoEx(2,0));     TrnSetPen(19, 3,  AssInfoEx(3,0));     Prompt("Test");      END     when clicked the pens set to the trend fine, i tried to run the code from a function but it did not work. i am new to citect and am sure i am missing something stupid.
