  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
  2. 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.  
  3. 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
  4.   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.
  5. Hi, I need the Service Release 1 (SR1) for Concept 2.6 XL English. Just I need the SR1 So any one have it and upload it. I have SR 7 but I need SR1. Thanks.
  6. 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
  7. Hello everyone, I have Concept version 2.6. However I have a few PLC programs that were developed with Version 2.2. According to Modicon, the Concept programs developed with version 2.2 can not be opened with 2.6 (higher version). Wow!!! However, if you opened them with 2.2 and exported them out to an ASCII file, then you can open them with version 2.6. My question is: does anyone have a 2.2 version? Can I please help me just to export them out? Thanks, Arde
  8. 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
  9. 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!
  10. 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.      
  11. Hi, Um new to plc and at the beggining i bought a Twido TWDLCAA24DRF old one without the cable.I want to know if any rs485 to usb cable is possible to programme this plc? please someone help me   is this cable is possible?
  12. Hello, i have a premium plc of modicon schneider electric i made the application 6 years ago and now i want to change my variables but my password does not work anymore or i forgot. does anyone know how to recover this or to crack my own password. th   suriname
  13. 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,
  14. 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?
  15. I am struggling with the following problem: We have a Momentum PLC running with a project downloaded from Concept 2.6. When I make a small change into the project and I download the change to PLC there seems to be no problem. But when I try to run a visualisation project in Vijeo Look then after any click in visualisation the yellow triangles with red crosses appear over every object on the screen. We run OFS to enable communication between PLC and Vijeo Look. We use non-allocated variables in the project and probably the Visualisation does not work well with those unallocated variables after project changes. Can someone please describe steps which need to be taken to compile or upload a Concept project so that it works well in Vijeo Look with unallocated variables?
  16. 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
  17. On Momentum PLC we have setup remote network modules as follows: On output modules with ADO 740 50 we have setup Last Value to Set to 0. Does it actually mean that the output value will be set to 0 in PLC memory immediately when PLC loses ethernet connection with the output module? We have setup hold up timeout on 170 ENT 110 01 on the remote side, but I am not sure how exactly the Concept parameters work with output remote modules. In the Concept documentation the process how Health Timeout and Last Value works is poorly documented. So the question is basically: How does Health timeout and Last Value parameters work in Concept Ethernet I/O Scanner with Momentum and remote output module ADO 740 50 with ENT 110 01? When timeout occurs in communication with output module ENT 110 01+ADO 740 50 and Last Value is configured to "Set to 0", does it mean that the output variable assigned to this remote module is set to 0 in PLC memory? If there are Timed out transactions on PLC with Health timeout expired, would that appear in Ethernet statistics on Momentum web page?
