Thank you lads for the contributions . I have checked on the website and unfortunately the version 9.8.09 is not available though I have sent a request for the same. If anyone has the this version I will gladly appreciate .

Hi all I have a Unitronics PLC on site .So two of the analog input channels appear to have failed because when I view the code online ,raw input data is stuck on 16384 regardless of variation of mA signal .I have identified spare channels and rewired those and proceed to update to the new MI . I can view online and see the new raw data corresponding to signal variations. Now when I want to do the download I get the following message '' To complete the download , a newer O/S version is required''. At the moment I am opening the program with Visilogic 9.8.91 and when I check signature log it shows the code was last modified with Visilogic 9.8.09. Kindly advise how I can get around this problem.I am of the opinion ,one doesnt need to do a software update after making only an minor change. Thanks
