    Sounds like you need WinCC flexible development installed, not just runtime.  Your project must have a WinCC flexible object that requires development installed.

    From the link below, download "WinCC flexible 2008 SP5 Compact/Standard/Advanced Trial":

    What is the output address?  (Ex: 0.00, 10.03, 100.11)

    What is the part number of your module with the output, which slot is it in, and which I/O screw terminal is it?  Did you check the I/O configuration for the actual address of the module?

    To append to what @Joe E. said...

    Depending on your system complexity and which HMI is connected to your S7-300, an upgrade to S7-1500 might be an alternative.  However, the S7-1500 does not have nor will ever have an MPI port - this communication should change to Ethernet.

    The cleanest solution is to add an Ethernet module to the S7-300.

    If the S7-300 and S7-1200 do not have to exchange data with each other, you can use a 6GK7343-1CX10-0XE0 module (CP 343-1 Lean - cheaper module)

    If the S7-300 has to initiate Ethernet communications to exchange data directly with the S7-1200: 6GK7343-1EX30-0XE0 (CP 343-1 module - more expensive)

    You can also use the CP-343-1 Lean module for data exchange only if the S7-1200 initiates the Ethernet communication to the S7-300.

    Yes, that's the same.

    I've contacted Evoqua but they won't respond.

    I'm assuming that I would need to be a partner to deal with them?

    I don't know about whether being a partner or not will help, but you will have to contact them anyway because it's not only the operating system you need, you'll need the HMI project as well.

    What is the part# of your HMI?  It looks like an OEM brand-labelled TP700, and may have a special firmware that is not available in TIA Portal.

    If indeed you have a CPU 216 (not to be confused with a CPU 226), then I recommend upgrading to an S7-1200.  The HMI would likely need upgrading as well. The 1st Gen S7-200 (CPU 21x) has issues with vibration.  I've witnessed this issue more than once - I even gently taped on one and watched all the I/O flicker.

    On the 3rd line, you're missing the instruction.  If your original STL is like this:

    :O    F11.0
    :O    F11.1
    :O(
    :A I81.6
    :AN    F11.2
    :AN    F11.2
    :O    I81.6
    :A    Q64.3
    :)
    :A    I64.6
    :A    I64.0
    :AN    F3.6
    :=    Q64.3

    Then the logic would look like the attached picture.  I tried it also with the third line as A(, but the logic doesn't make sense this way.

    Please check your STL code you posted, and make the necessary correction.

    V1.1 and V1.2 are firmware (operating system) versions of the C7-621.

    If you have the unit, you can see the firmware version online.  If you don't have it, and don't know the firmware version, choose V1.1.  You can always replace it with V1.2 later if you find out it is V1.2.
