    Look in the Help for the Slave Address definition table. Timer presets start at C000 hex, and timer currents start at D000 hex and are 32 bit words. For T35 preset, try address hex C023 (decimal 49187). Joe T.

    In revisiting this after some zzzzz, also don't forget that Modbus addressing starts at 1, whereas Vision starts at 0. Sometimes you have to allow for this "difference of 1" when specifying the addresses. It depends on how the slave is set up....some also use the Vision style. Easy enough to find out for sure once you actually get a successful connection. Also, you have fallen into the trap of counts starting with 0...... MI4000-MI4027 is actually 28 MIs. cheers, Aus

    I'm only looking quickly and might miss something, but SB2 in your third rung is only calling the actual read on power up. You need this to be an actual call from other parts of your program, whenever you want it to happen. Would be nice to see the actual settings in Com Init 2. And don't use PLC Net ID, especially 0. If you look at the dropdowns that then happen, you will find preset determinations of what they do. Instead, do a direct store into SI8 of whatever unit ID number you want the plc to be. For Modbus I generally make the master "2". This allows for some later additions to a network that might default to 0 or 1. Your other understandings seem good enough, but no doubt I have missed something somewhere. Try my suggestions and see how you go. cheers, Aus

    Hi all, This Topic will list items that are worth an easy find, but are not quite "pinnable" on their own. If we pin everything that is useful, it will all become one big mess on page 1 (or bigger!). I suggest that if you want something added to the list, contact myself or another mod to have them edit it into this existing list that I see as having carefully considered updating. To save space, only links will be shown, not full previews, with the Header or a Description listed before the link. Sometimes the link will take you to a particular post within a Topic that is the answer, but a full topic read will never go astray....history is useful.
