  1. Thank you very much for your advice
  2. In this case, I'd like to inquire about the safety of downgrading the firmware. If I proceed with the firmware update (downgrade), is there any risk of losing the program that is currently stored in the controller? I want to ensure that the program remains intact during this process. Thank you very much
  3. Hello everyone, I'm facing an issue while trying to go online with a PLC. The firmware revision of the controller is 34.011, but the offline project I have is showing a firmware revision of 33.xx. Due to this mismatch, I'm unable to establish a connection. I'm relatively new to this company and recently learned that the program on my computer may have been modified by a contractor company, which might explain the version difference. I suspect they may have used a higher version of RsLogix when making the changes. I'm looking for guidance on how to proceed in this situation. Is there a way to update the offline project's firmware revision to match the controller's firmware revision? Or is there another solution to resolve this compatibility issue? Any help or insights would be greatly appreciated. Thank you!
  4. Hello everyone,   I'm working on a project where I'm using Vtscada Light to communicate with a MicroLogix 1200 PLC. Currently, I can read values from the PLC without any issues. However, I'm facing difficulties when attempting to write values back to the PLC.   Setup: PLC: MicroLogix 1200 SCADA Software: Vtscada Light Communication: Rockwell Driver with a serial port and serial-to-ethernet converter   I'm looking for guidance on the proper method to write values to the. If anyone has experience with this setup or similar, your insights would be much appreciated.   Thank you for your help!  
  5. Hello everyone I'm reaching out to seek your insights and expertise regarding a challenge I'm facing with a recently acquired plant. The plant utilizes a MicroLogix 1200 PLC to control a HighService water system, and I'm encountering difficulties in establishing communication with the PLC and retrieving its program. Here's the current situation: The MicroLogix 1200 PLC is equipped with a serial port for communication, and I'm attempting to connect it to my Windows 10 computer. Despite trying different USB-to-Serial adapters, including the Prolific PL230GT, I haven't been successful in establishing a reliable connection. I have thoroughly checked the cabling, switch settings, and even disabled the firewall, but the issue persists. I have also attempted to auto-configure the connection using RSLinx, but with no success. During my investigation, I came across information about a Communications toggle button located on the processor of the MicroLogix 1200 PLC. The datasheet states that this button allows switching between user-defined communication configuration and default communications mode on Channel 0. The Default Communications (DCOMM) LED indicates when the controller is in the default communications mode. In light of this, I have the following questions: Could the use of the Communications toggle button have any impact on establishing communication with the MicroLogix 1200 PLC? Should I consider toggling the Communications toggle button to potentially reset the communication settings to default values? Are there any precautions or considerations I should be aware of when using the Communications toggle button? I kindly request your insights, suggestions, or experiences related to the use of the Communications toggle button and its potential relevance to resolving the communication issues I'm encountering with the MicroLogix 1200 PLC.  
  6. Hello everyone,   I'm seeking recommendations for training programs or resources focused on building control panels. I have a basic understanding but want to enhance my skills in design, wiring, components, safety, and troubleshooting.   If you have attended any reputable hands-on training programs or know of online courses, I would greatly appreciate your suggestions. Any personal experiences or tips are also welcome.   Thank you for your assistance!   Best regards,
  7. Hello, Thank you for your response and for providing valuable insights into the possible causes of the configuration issue. I greatly appreciate your help and expertise. I have successfully resolved the configuration issue. After thorough troubleshooting and confirming the module profile and settings, my flow meter is now up and running smoothly. Your assistance was instrumental in resolving this problem, and I am grateful for your guidance throughout the process. Thank you once again for your valuable contributions. Best regards,
  8. Hello,   I'm seeking some guidance and assistance regarding an issue I've encountered while configuring a Proline Promag W 400 flow meter module in Logix Designer. I'm experiencing the following error:   Error Code: 16#0009 Fault Additional Code: 16#0000 Fault Description: Module Configuration Rejected: Parameter Error   I've carefully reviewed the module documentation, verified the wiring connections, and ensured compatibility between the flow meter module (Serial Number: T711F49000) and Studio 5000 Logix Designer (Version 33.00.00 Full Edition). However, I'm still facing this parameter error during the configuration process.   I've also attempted to access the web service provided by the flow meter module to view its configuration and parameter settings, but I haven't been able to identify the specific cause of the error.   I would greatly appreciate any insights or suggestions from the forum members who might have encountered a similar issue or have expertise with the Proline Promag W 400 flow meter module and Logix Designer. Specifically, I'm interested in any troubleshooting steps or guidance that could help resolve the parameter error and successfully configure the module.
  9. I have an inquiry about the best IoT plan for an alarm system that sends SMS notifications. Our company is currently deploying an alarm system, and we would like to configure it to send SMS notifications to at least 10 cell phones in case of any incidents.   We are planning to use a cellular modem connected to the main server, which would have a SIM card from AT&T. However, we are not sure which IoT plan to select for this purpose.   Based on our requirements, we would like to receive SMS notifications for any incidents that occur on our alarm system. We estimate that we would send around 100 SMS messages daily, with an average message size of 160 bytes. We would also need to ensure that the data usage for SMS messages is kept to a minimum. Has anybody worked with an AT&T plan that allows sending and receive SMS's for alarm notifications?
  10. 1734-aent-c Error 16#0203

    Thank you very much.   My las RPI was 30 and I changed it to 750.
  11. 1734-aent-c Error 16#0203

    Yesterday I change the RPI of the 1734-AENT/C, and the problem seems to be solved, does anybody knows why this fixed the error?
  12. 1734-aent-c Error 16#0203

    Excuse me if I did not explain myself correctly, I am new to this whole world of automation, we are a water treatment company, in one of the water storage towers we have a pressure sensor with which we monitor the water level of the tower, it is It communicates by radio frequency antennas with the main plant where the PLC that receives the sensor signal is located. Last Sunday we had one. The values that we began to receive went to zero in fractions of seconds, then we had the correct reading, preceded review the PLC data and I saw that this fluctuation was there, I went to the tower and proceeded to check the sensor but everything was correct there were no voltage or current drops, but I realized that the 1734-aent-c module was blinking on red (point bus status and network status), IT connected to the router that is in the tower and pinged the module which responded to all with minimal losses, from the same router it pinged the PLC and there was still minimal losses of a large number of pings that were made so it cannot be some communication, I attach the screenshots of the RsLogix diagnostics.

    I talk to the IT department, they did everything but it seems there is no problem in the network
  14. I'm having troubles with a 1734-AENT-C module, I'm new in the company and last week me started to have this communication issue with this module, communication between the module and PLC began to fail and in RSLOGIX apears 16#0203 (Connection timed out), but this code appear and disappears, the connection is stablished for a few seconds and then it returns the same error, I have a little experience in PLC's, I don't know what could be happening, can someone help me with this issue?
  15. Im knew learning PLC programming and I'm trying to connect to a PLC but It does not appear in the "Who active" window but if I look for the PLC in the RSLinx it appears in there, anybody can help me with this?
