  1. ASCII Code 8 Byte In Twido

    varun_pandey posted a topic in Omron

    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

  3. Hello. I am working on an a machine automation project. I come from an Allen-Bradley background and am new to the OMRON environment. However so far the difference has appeared slight.  My current issue, involves an MCH71 motion controller and an 'ORIGIN SEARCH' Routine.  I am using MECHATROLLINKS II for the communication. I have set up my Registers just fine in CX-Programmer and have successfully performed jogging and incremental move functions from CX-Programmer using ladder instructions with the required bits sent to the MCH. I am however at a bit of a hurdle with the ORIGIN SEARCH function. I have read the manual numerous times. I have not been able to determine where exactly the Limit Switch is to be terminated to become a 'point of origin' so i can perform an origin search command. I will be using a single point of origin (Limit Switch) I have included any relevant documentation that I could dig up. It would APPEAR to me that the limit switch must be terminated to '41' I do not know what that refers to in terms of I/O points. (This was an old demo unit that I am now to utilize for a 3 axis machine...) I might add that this is my first motion control project. (I am from process control background) Each servodriver unit has a break-out I/O terminal block. I find no reference to '41' on any of them. (The 'P-OT and N-OT' have been disabled within the system parameters as well.) I plan on using these parameters;  1 for P4AA01 1 for P4AA02 (could this be wrong) 1 for P4AA03(also unsure) 1 for P4AA04(this i am pretty sure about) 0 for P4AA05(this i am positive will be required for accuracy) P4AA07 will require tweaking once i have set this up.    It is all in test mode and the servos are just secured to a test bench....Thanks.

  5. 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.

  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.

  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. Hi I have a big issue with machine user access using loggin and password. There are different levels of login (operator, maintenance and admin) locked with physical key or password. The problem is that whenever any other user sees the password or got the key he can use it later. Is there another efficient way to lock the access and may be record who is logged when and how? Thanks  
  13. Hi all,  Can someone please help me, I am using a Micro830 Controller running connected components workbench software to program the controller. I want the use the Real Time Clock of the controller to control an output to turn on everyday at 01:30am and turn of when it receives a signal from an input. The output will control a backwash valve that will operate and activate a cam switch internally that sends a signal back to the Controller to say the valve has operated and can now stop sending the signal to the valve. (if that makes sense). I have tried playing around with the RTC instructions but I cannot seem to get it to operate how I want it to. Any help would be much appreciated. EnvrioService
  14. 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
  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.      
  17. 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?

  19. 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,
  20. Hello Dear friends, I have following two problems in RSLogix 5000. I just started working with this software. I am using RSLogix 5000 for my project and I want to use inbuilt drag and drop elements like measuring instruments for example Voltmeter etc. in my ladder diagram. Does it possible or do I need to add some libraries or add ons for that?  I want to plot graph of different properties with respect to time in RSLogix 5000. my question is again the same; what is the way to do it or do I need extra Add ons?  Thank you in advance for your help :) Merry Christmas!!
  21. I would like to bring up a topic that I've been been bouncing around in my head for the past few months. I make a living as an industrial programmer, sequencing using PLCs, dealing with drives, networking, controlling heavy machinery. All the hardware we use are from established companies like Allen Bradly, Sick, Cognex, Delta, ABB, etc... big $$$, you pay for the software, pay for the hardware and pay for the support. It's not uncommon for a large control system to cost $50k+ (hardware only) By night I'm just your regular maker. Programming AVR series uC, ARM series, playing with various open source hardware Arduino, RPI, Teensy, 3D printers, designing PCBs, stepper motors... whatever I can get my hands on. Both worlds are the same... but completely different, and there is ZERO overlap. I'm interested in why other people think this is, I'm sure that makers don't get into the industrial stuff because the price point. I'm not going to pay 8k for a AB Logix rack... are you kidding me? but vice versa? is the lack of support really all that daunting? I find OS stuff to be way more powerful, understanding something from the bare metal is the most amazing feeling, and being able to modify it to your needs is even better. Digging into somethings source is without an argument the most flexible platform to build on, and knowing the board level schematic for a chuck of hardware opens up a world of opportunities... Then lies the ethical dilemma... If I was to profit off other people's work, does this make me a bad person? What if I push the changes back into the development (which frankly I have no problem doing) I would love to head other people's opinions...

  24. 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?
