  1. Hi All, Has anyone used a Compactlogix PLC to send a SMS via a Router? I've seen it in the past using a serial connect using ASCII. Unfortunately I can't use email as network coverage can be bad at times.
  2. Hi, New to the forum and pretty new to PLC programming. I took the 3-day Sysmac training a couple months ago, but just recently set up one of the NX1P2 units that we'll eventually use for a robotics application. Right now I've got it set up just to experiment with, so I have 3 physical switches (1 momentary, the other 2 toggle) and 4 indicator lights hooked up. Ladder program is set up to light up different LED's when the momentary contact switch  I_SW1  is pressed, based on the position of the other 2 switches. Here's the issue:  When both of the toggle switches are ON (see lines 4 thru 8), all of the LED's light up as expected as soon as the momentary switch I_SW1 is pressed. However, if either or both of the toggle switches are OFF (see lines 0 thru 3), even though it seems like the logic is correct, nothing happens on the output. Lines 0&1 were modified as shown to see if using the variable O_Light1 instead of going directly to O_L1 output would work, but it didn't make any difference.   See attached images for example of working and not working ladder sections as the momentary switch is pressed. In the "working" image, both the toggle switches are on. In the "not working" image, both toggle switches are off. PLC's input & output indicator lights match what Sysmac is showing in the monitor screen, so I'm pretty sure it's in the ladder logic and not the physical wiring.   Thanks for any advice.
  3. Hi, In our machine, we want the homing of linear axis to be - moving to reverse limit. In order to achieve that we connected positive limit to Enable_positive input, negative limit to Enable_negative input of MC_Power function block. We used MC_Home function block and assigned the negative limit to bCalibrationCam of home FB. Things were working correctly.  But one thing we noticed is if the axis is in synchronous operation mode(axis following another master axis), even the limit is engaged axis is not stopping. During discrete movement this was stopping. Is there any other way to configure limit switch in twincat3. 
  4. Hello Everyone I am new on this forum. As an electrician in Denmark, I have just gotten a fountain to maintain. The control cabinet and pumps are all underground in a couple of wells.   There are a lot of monitoring and time is spend / wasted lifting the heavy manhole covers and driving to and from the wells. I would like to install a plc to monitor the few settings I really need. Are there some with experience of how and what type of equipment?  I am considering a siemens LOGO with a communications module and just buy a sim card.  Is it better to use prepaid 2G, 3G or 4G or only data sim card?  Also with or without pin code? It is not possible to establish a wired communication connection but the wells have of course 230 V mains and is very close to a phone tower. Yours faithfully Morten Lund
  5. Hello, On our DCS we have a button that will open an RDP connection to our PLC server and open the .mer file connecting the DCS to the PanelView HMI. This is supposed to be used for troubleshooting purposes only, but that is not the case. Is there a way to prevent operators from operating the HMI through the RDP while still allowing them to have read only access?   Thanks, Michael

  6. GT Designer

    PLC Rookie2021 posted a topic in Mitsubishi

    I am newer to GT designer. Ive used it a couple times years ago but I cannot figure out how to create a 3 position switch and cant really find any info on it? Is there a special way to set a switch up so that eveytime the operator hits it it changes the state or picture of the switch from left to up then to right and back? im sure its probably just something that im not seeing in the properties menu but any input would be greatly appreciated. 
  7. Hi Experts, I would like to know is there any possibility to make a switch that can make exponential increment to a data. i know how to make a switch to increment data in fixed intervals with a switch but im trying to make a switch when you press it continuesly it should increase the gains rapidly over time. is this possible and if yes can someone explain me how? im attaching a sample image how i want to make two buttons to increase and decrease a data. thank you in advance guys. kind regards, sathu.

  8. Switch LAMP latch

    MarinusS posted a topic in Mitsubishi

    Hello  I'm new with GT Designer 3, I'm writing code for a GOT2107 HMI. I have a few buttons that when you press it, the LED on the switch comes on, and when depressing the switch the LED goes off. That's good, but how do I create a latch, that when the switch is pressed and depressed, the LED will stay on. and only go off after the next press and depress?   The attached image is my working switch button. Regards Marinus    
  9. I have a Modicon NOM0200 unit connected to an access switch to send commands to various rs-232 devices. The Access switch requires a "disconnect string" to end communication with a particular port. The disconnect string is "CRTL+D", how can I send a "CRTL" keystroke from the NOM0200 unit? I know for carriage return it is "$R" is their a similar combination I can enter for "CTRL"?  

  10. Ethernet/IP bandwidth

    andepand posted a topic in CX-Programmer

    Hello, A while ago I modernised a magazine gathering / filmwrapping machine. This was a fairly big project for which I used an Omron CJ2M as the main PLC, 10 Wago Ethernet/IP fieldbus couplers, a Keyence CV-X420 vision camera and an Omron NS12 HMI.  All of these components run on the same network which contains an unmanaged switch where the HMI, PLC and the first Wago are connected. The Wago’s act as a two port switch since they are all daisy chained. At the end of the Wago chain there is also the vision cam which is connected at the last Wago coupler. At the time I was advised against using Broadcasting instead of Multicasting with a managed switch, but I tried anyway since my networking knowlege is lacking. Also, the only ‘bandwidth demanding data’ comes from the vision system. The Wago couplers contain only digital I/O and high speed encoder inputs run directly to the CJ2M. I haven’t run into any trouble so far and the machine is already producing for over a year. Now , a new project is on the way and it will need even more Ethernet couplers, 15 to be precise.  This brings me to my question; is there a limit to the number of nodes in an Ethernet/IP network and will I possibly run in to bandwidth problems by adding more remote I/O and not using a mannaged switch? Also, I would like to get high speed input out of one of the Wago couplers. Thanks in advance for any feedback! Greetings from Holland Andy 

  11. Switch Superimposed Window

    Russ McKenna posted a topic in Mitsubishi

    Using GS2107, FX5U. I want to change the JPG image on a screen based on if the value in a text box is either 1 or 2, any other value will also have a single default image. Is there a way to do this via script? Or is there a different way?  
  12. Good day to all, I am trying to establish DDE communication between my PLC (1769-L23ER) and MS Access via RSLinx Classic Gateway (3.9) over Windows Server 2012 R2.  On my developing PC (Windows 7), there isn't any issue at all. But when I port the codes over to Windows Server 2012 R2, MS Access is not able to establish DDE communications with the PLC.  I was wondering what went wrong. The error message from MS Access is "MS Access can't find the specified application and topic because it can't open the DDE channel, err.Number is 282. The code for getting the channel is as follow OpenRSLinx = Application.DDEInitiate("RSLinx","PLC-D") I was wondering was there anything I have miss out. eg. Configuration of the server, path settings, etc.. Any help is welcome. TIA Cheers CY

    Sajadh posted a topic in HMI & SCADA

    I have connected weintek 8103ie with fx3u 128m (Mitsubishi). The problem is when I create a toggle switch to hold an input on PLC it doesn't work. But momentary switch works properly. For eg. I want to keep input x1 of PLC on when I press a toggle switch. Also I want to run a coil when I hold a touch input. I can't achieve this in ebpro (IAM new to hmi ) but ok with PLC program.please help

    Hi Guys, Im using delta eserver to get data from access and there is an error. How do you solve this? Eserver is installed on windows server 8  
  17. Was wondering if anyone can tell me whether it is possible to use the Red Lion Graphite displays to remotely log into your system via Ethernet for programming.  Can it be used as a bridge to other Ethernet devices connected to it?
  18. I am fairly new on this forum & PLC's, usually i read and get tips from here.I use a RsLogix 5000 PLC software. I am currently working on a project at home that requires me to read from a Access DB. What type of Instruction or method do i go about, initially reading from Access? I know Excel is possible It's an existing system. Add on functionality/feature. I am using a barcode scanner that will link up to a Access DB to verify the barcode is legit and send this info to a different system via PLC/EthernetThe access DB is used because its a older system, it uses that. So it is possible? and guessing from what your stating, its is more involved to get the system working eventually?PLC = A&B 1769-L23-QB1 CompactLogix Controller I am using FactoryTalk View Studio as HMI, do not have SCADA.I have a control logix chassis. Thank you in advance...

  20. PV800 HMI multiple position switch

    willings posted a topic in HMI & SCADA

    Hi all I am setting up a batch tank system, I have 1 pump which can pump to six different tanks(via pneumatic actuated valves). This is my first go with a HMI, usually I would use a multiple position switch. Is it possible to make a six position selector switch with a HMI? I am using a AB Panel-View 800, has anyone done this before? Any help would be appreciated.
  21. Hello everyone! I need your help.  I use the PLC: Q06UDEHCPU and the module: QJ71MB91. I programmed in the program GX Works 2 I instaled a library of "QJMB91ModbusSerial_V120 (FB - QJMB91ModbusSerialMaster)" and using it wrote temperature sensor interrogation program. The sensor is interrogated by the channel 2 and has the following switch settings:  Switch 1 - 0000; Switch 2 - 0000; Switch 3 - 0000; Switch 4 - 0A04; Switch 5 - 0000; which are specified by the PLC parameter in GX Works 2. I found an example of writing a program to install the switch settings in the user manual QJ71MB91 using ZP.UINIT instructions. I wrote a program to this exemple. Not prescribed bit address, which should be established when the program is executed (M0) (ZP.UINIT  "U4"  D0  M0). I wrote: ZP.UINIT  "U4"  D0  .  After executing ZP.UINIT instruction PLC stops working, blinking error, settings module is not install. How can I write a program to configure the Switch Setting?
  22. 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  

  23. Modbus TCP Data Logging to Database

    gclshortt posted a topic in HMI & SCADA

    Here is a recent post that I would like to share. Using Visual Basic 2015 we will log three holding registers from the PLC along with time and date into a Microsoft Access Database. We will log every minute into the database with the information that we collect from the PLC via Modbus TCP (Ethernet). All code will be done and shown so you can implement this in your application with different parameters. The information collected in the database can then be distributed or analyzed in the future. Visual Basic 2015 will be used with the EasyModbusTCP client/server library for .net. We will communicate to an Automation Direct – Do-More PLC. Using the free simulation software of the PLC Designer Software, we will retrieve three values of the Modbus Holding Registers using Modbus TCP. Once we have this information out of the programmable logic controller it will be placed in a Microsoft Access (2010) Database. This will be done by using a SQL command to insert the data. Read the rest of the post... Let me know what you think, Thank you Garry http://accautomation.ca/

  24. Program 16 position rotary selector switch

    michael.southerland posted a topic in CX-Programmer

    I have a 16 position rotary selector switch I'm trying to program to a CQM1 PLC, that I will also be programming to a micrologix 1200 in the future, using CX Programmer. The switch connects to the PLC using 4 inputs, and activates the inputs in a binary pattern 0-16 as I turn the switch. For example: if the switch is wired to the first four inputs of the PLC, and is turned to "9" 0.0 and 0.3 will be activated and 0.1 and 0.2 will not, just like binary 9 = 1001. I have tried several things trying to get the PLC to accept these inputs as a single "data-point," and then convert to BCD or Hex to use in a timer. I'm having no luck! Does anyone have any ideas how this is done? The switch is a Tosoku DPP01 015L20RCB, and because of the age of the PLC my instruction set is limited. Thank you in advance!
  25. Use to working on DC inputs, now I have a PLC I am playing with and the digital inputs are AC, can I still just wire a on/off switch to complete the circuit just for testing? This is a micrologix 1100.
