  1. hi guys, is there any easy and global way how check if the same device isn´t associated with multiple labels? (ie M_start M300 and M_whatever M300)
  2. QCPU to 2x kyence iv2

    ok, solved, I made a rookie mistake and trusted what the maintenance and production guys told me.
  3. QCPU to 2x kyence iv2

    Hello all, we are using Q03UDECPU and via built-in ethernet port its connected to two IV2-G30. (through unmanaged switch) to establish connection we are using FB LQnUDEEthActive (hereinafter referred to as  FBLQ) two instances of FBLQ in two instaces of our FB which is responsible for creating messages that are then send via FBLQ Both keyence devices have different IPs, ports and connection number. Problem is that it is working flawlessly, except the time its not working :/ from time to time it simply doesnt trigger Keyence device. It looks so far like its independt of turning machine OFF/ON, also both keyence devices are used in different times (about 10-20seconds of difference) Im currently working on sime kind of internal diagnosis to see whats happening when its not working, but im just curious if there is something obvious we are missing? any help will be apreciated Thanks

  9. HMI on CC LINK IE FIELD

    its GT2508-VTBD, we have it connected to R08EN CPU, via cc link ie field in ring configuration....   It works okay, but when you need to change value displayed on HMI its little bit of pain in the ...
  10. HMI on CC LINK IE FIELD

    its part of long CC link chain, it would mean extra cable through line
  11. HMI on CC LINK IE FIELD

    Hello all, kinda lazy question, but I'll rather ask, before I'll went to deep into HMI scripting. Because of a design of CC link, there are RWr and RWw Is there any simpler solution for displaying value stored in PLC, while also letting HMI operator change the value and save it to PLC, than scriting in HMI? hope it makes sense to you thank you in advance
  12. CC LINK Communication Error

    according to mitsu manual  (chapter 8.1) when LERR is flashing its caused by conection cables
