  1. Hello all I am have FX3G PLC, where i am trying to use SPD function for speed monitoring and controling. currently i am working on software only. I am using x4 as input (s1) , sk1000 (s2), and d4 (D) in monitoring mode when i am forcing X4 to ON/OFF ,  there is no any value change occure on d4 i have tried to change the s2 value from k1000 to k10000, but not fruitful i need your valuable support to confirm that my primary setup is correct or not and what things are required/missing attached program screeshot  
  2. Monitoring a register

    How do you ensure a time value in a memory register coming from an external device is constantly changing in an omron cj2 plc and trigger an alarm when it stops. At my company we scan in a work order with a barcode scanner tied to a different network than the one the plc is communicating to. We use a specific register in memory to determine if these two networks are communicating. We use a date time value in seconds going to that specific register, as long as the time continues to run we know we have a communication link. If that time ever stops in that register we know the communication link is severed. I need to know if there is logic that can be written in the plc to notify an operator when there is no communication link.
  3. I have a level measurement system by fmcw radar (Rosemount tankradar), for a filling-emptying process, of very large water chambers. Very sporadically, the radar is momentarily lost and measures 4 to 7 feet below the actual level, only when filling the water chamber.  Sometimes the measurement freeze in the middle of the filling process.  Due to the criticality of the process, this behavior is dangerous, as it can cause flooding inside the plant This behavior is very sporadically so we are baffled about the root cause of this problem.
  4. Hello, I'm looking for a simple data logging software, something that doesn't require any programming skills. Thank you!
  5. CJ2m and NB10

    hello guys, My situation is, I have an HMI nb10 and PLC CJ2M-cpu31. My question is, how can I monitor my system with this two set up of Omron device thru online or web base .

  6. I'm doing some remote support on an FX5U with GX Works3 on the remote desktop. I've been doing this for a couple of weeks without difficulty. Yesterday the ladder monitoring stopped working. There is no ladder contact monitoring showing and D registers and timer values are blank. The Watch windows are working correctly. Online Write Monitor is selected in each case. All Tools | Options seem correct and match my local copy of GX Works3 that I used on site. Any ideas?  
  7. Current Monitoring

    Greetings, I've been having some issues with a vacuum pump breaker tripping... I think I've figured out the problem and resolved it but I noticed that several of the other motors have current monitoring on the HMI but the person who set this up is no longer with us.  I'm wondering what I need besides an analog input for my control logix processor (which I have) to setup this project.  I'm not sure if the other motors are just monitoring one leg of the 3 phases or if they are somehow showing total current?  any ideas and recommendations would be greatly appreciated.   thanks,
  8. Hello, anyone know how to make a logic that monitors the change in position of a carriage through some rails ?. In my application I measure the position of the carriage by means of a laser sensor and I have to detect if the laser beam is interrupted when the carriage is stationary or moving. I have implemented a logic as the adjunct file, but doesn't work.
