  1. Retentive OTE

    Thanks, I'll see how we end up with solving it. I would just prefer to keep it in ST if we can, but it would be so much more simple, if there was an equivalent to := in ladder also.
  2. Retentive OTE

    I know about OTL and OTU, however then the logic have to be rewritten, as the OTL needs to have an separate and specific unlatch logic for the OTU. While a "retentive OTE" and := in ST, just need one and the same logic that will be true or false. To ask a stupid question, is there a smart/simple way of using OTL and OTU to represent "retentive OTE" and := in ST? I don't see it, but it seems like this was exactly what was discussed and had a solution in this link. http://forums.mrplc.com/index.php?/topic/7252-retentive-bits/
  3. Retentive OTE

    Hi. Is there a way to make/code an OTE to act like a retentive OTE? So it will retain its state when the PLC is power cycled? Similar to the the assignment symbol := in structured text. It seems like what I'm looking for was discussed here. However they reference to code/attachments that doesn't seem to be there anymore. http://forums.mrplc.com/index.php?/topic/7252-retentive-bits/
