  1. I can debug my plc app with simulator. I created some function block, and inside functionblock I can inspect in and out parameters, as well as local variables. But in/out parameters values are not shown. Any solution? Im using Sysmac Studio 1.29.2 and selected a NX PLC in my project.
  2. Hello! I am beginner in PLC world, also in SIEMENS PLCs. I managed communication over private network. Now I have a problem that I get same values on all inputs. Picture below shows my configuration of driver and data monitor. First picture shows values when input I0.0 is in state 0. Second picture shows values when input I0.0 is in state 1. Physically on PLC only input I0.0 is forced to 1, input I0.1 stays 0. But data monitor shows both inputs as state 1. Where is problem? Is problem in PLC program, TIA portal? I saw some guys using DataBlocks but I am not skilled enough to use it. Third picture shows simple PLC program on my PLC. Please help. Thanks in advance!
  3. GX Works 2

    Hello everyone! Can anyone suggest to take all the Input and Output (digital) status at a time in a single file for backup in gx works2 in FX2N PLC. I need to confirm that all required IO are in perfect condition before start operating the machine. Also I plan to design a troubleshooter to find problem.
  4. Hi, I have some trouble with a CJ2M-CPU33. My client did a backup to memory card earlier today, and after this we did some changes through remote link. Now the client wanted to restore the previous backup to the PLC and has done so, but the system would not function correctly. After going online on the PLC it seems like the PLC is stuck in "Stop/Programming Mode". When trying to change to "Monitor" or "Run" mode a dialog comes up containing the following message: "Failed to change the operating mode. The operating mode may be still changing in the PLC."  - All the dip switches are set to off after restoring backup - The PLC has been rebooted  - I have downloaded the application again through CX-programmer  - Verified that the PLC is set to start up in "Monitor mode" But nothing helps. The same message comes up when trying to change the operating mode.  Hoping anyone can help to resolve this issue as it is very critical for us and the client. In advance, thanks for any tips or help received. Best regards Stian

  7. EMS provides low cost analog sensors useful for PLC analog inputs. For example the $25 temperature sensor (+/- 2%) is a useful and inexpensive way to monitor for an over temperature condition in a panel cabinet. emssensors.com AC voltage and current transmitters can be a useful way to monitor motor performance. Even the sound level sensor can be a good way to generate an alarm condition for a bearing failure.
  8. I am trying to find a way to do a "batch monitor of Global Labels" in Mitsubishi GX Works2 Software. I can monitor Device/Buffer Memory Batch but can't find a way to monitor all Global Label's status online? Can anybody help me on this?
  9. DIY CO2 Controller

    Guys, I find CO2 controllers to be too expansive and ugly at 500 $ How can I Take a CO2 sensing chip read it it's signal compare the signal to equal or above a value turn on an AC plug (Type B) when below value, OFF when above valueBaiscally, I want to make a CO2 controller myself (soldering on board, buy individual components, put in a box) This will release CO2 in the room through a solenoid when below 1200 ppm, and shut off the solenoid when above 1200 ppm IF I'm on the wrong forum, could you advice where to ask ? Thank you ! Dominique
