Plant Scada Studio 2020 Digitals

[Steve00]

Hello everyone,

Hopefully there is some that can point me in the right direction.

I am developing a Standalone project with a single IO device being a Compact Logix PLC.

I have communications up and running with all INT's DINT's and arrays and this seems to work fine.

The issue I am having is with Digitals. The Runtime does not read or write to digitals. I have tried a single digital thinking there was a problem with data structures but still doesn't work. The runtime can change values in the PLC animate anything as long as it is not Digital IE a Bool. Runtime seems to read the digitals (not BAD) but variable doesn't change either by Runtime or manipulating in the PLC code. The Bools just stay as a zero. Is this something anyone else has experienced or and I missing the obvious.

Thanks in advance

Hi Steve,

Versions of the ABCLX driver prior to 5.00.04.000 had this problem.  I suggest you check this and if necessary, update to the latest version.

Updated driver and works fine. Thanks for that much appreciated. Sometimes we just need a little prompt.
