Byte Swap Not Working in WoV 6.0

    Hi,

    I am trying to communicate a 16-bit UInt from Robot to a Siemens S7-1200 but I cannot figure out why the byte swap is not working.

    KRC4 KSS 8.6 + WoV 6.0

    Here are screenshots for the IO mapping and byte swapping in WoV:

    The signal is defined in $config.dat:

    Code
    ;==================================
; Userdefined Variables 
;==================================
SIGNAL MTEC_SET_FREQ $OUT[17] TO $OUT[32]
SIGNAL MTEC_RUN_PUMP $OUT[33]

    And set it to 1 in the SmartPad, but in TIAPortal, I receive it as 256. There is no byte swapping in TIAPortal and I also checked the signal bit by bit. The byte order is not changing, no matter if I configure the byte swap in WoV or not. It's always LSBF!

    256 on the robot is received as 1 in TIAPortal, so I'm sure the addresses are not shifted.

    Am I missing something?

    Any help would be highly appreciated. :tired_face:


    Many thanks in advance.

    yup... if only change is IO setup, that will be it. it may be an issue with WoV. what version you have there? and this is not pretty but it only need to be done once and should solve it no matter what:

    1) read pinned topic: READ FIRST...

    2) if you have an issue with robot, post question in the correct forum section... do NOT contact me directly

    3) read 1 and 2

    Thank you for your suggestion. The thing is that I asked about one signal, but I actually need many. I prefer to swap the bytes in the PLC program if it comes to that.

    I'm using WorkVisual 6.0.29_Build3018

    I just realized that after I deploy the project, if I compare the local project with the controller's active project, there are some differences left. It includes Bus Config for EMD, System Machine Data, and 8 files (screenshot). Is it normal? Could it be the problem?
