LabVIEW 2015/2016 Workaround  - Sep 2, 2016

Please see this forum post (http://forums.ni.com/t5/LabVIEW/COMSOFT-Profibus-driver-incompatible-with-LV2015/m-p/3341767) with a workaround. We will have a KnowledgeBase article on this shortly, and are simultaneously working on the next version of the driver.

LV2015 problem, VIs missing  - Aug 31, 2016

Same problem, no VIs in the palette after installing the driver. LV2015 32bit version.

version 1.3 is not compatible with Labview 2015  - Jun 26, 2016

the current driver version 1.3 can not be installed under LabVIEW 2015. after the installation, profibus VIs can not be found in the function board -> addons. when I try to copy the VIs from LabVIEW 2014 to 2015, the express VIs can not be used.
