  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. 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
  3. 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
  4. 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"?  
  5. 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
  6. Hi, I have a a few substations and I´d like to have a local SCADA in each of them. What is the best scada to use with reasonable price? Does anyone know if there is a solution without the need to have a PC for each substation? Thanx
  7. Dear Everyone can help     i have a batching system of about 12 materials and i need to generate a report for all batches in the day in runtime, i tried using SQL with Cicode but sometimes i can't find some material's data or to be Zeros. did any one here know a way to do that?? vijeo citect 7.4 thank you
  8. Delta eserver problem

    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  
  9. 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?
  10. 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...
  11.  Hellow Mitsubishi Experts    . I want to update my system . My machine have Mitsubishi plc system . Details of plc - CPU FX1n-60MR-001 Expansion Module FX2n-8EYR  . We have two factories .In one factory have this Mitsubishi plc system (LOCAL Location ) .So from other factory (Remote Location ) I want to check some plc data via internet using some interface (Ex visual studio interface )  .It is mean I want to remotely check some data (machine production units ,machine speed and etc )  . I have plc program and plc software .   So what i want to add external modules to this system .?   How can i implement my design ?.   . I m appreciate ur immediate reply .       Thank you.   Tharindu  
  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. 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/
  14. http://accautomation.ca/now-you-can-have-robust-data-logging-for-free-part-1/ YouTube overview: https://www.youtube.com/watch?v=6Xa2HYVOxE0 Robust PLC Data LoggerWith traditional loggers, software will read the memory of the PLC and store in a local computer. If the network stops or the PLC communication fails then the logging will stop.Creating a robust PLC data logger allows the communication to be stopped for a period of time without losing any of the data for collection. This is accomplished by storing the data locally on the PLC until communication is restored. All of the data is then read without loss. The amount of time that the connection can be lost will be dependent on the memory size of the PLC and the frequency of the data collected.This series will walk you through the steps to create and implement a robust PLC data logger using the following equipment and hardware.
