nkwai Posted November 11, 2013 Report Share Posted November 11, 2013 Hi, A friend asked me to modify him a scada software, he wants to change some controls. The scada software comunicates by modbus with a V120 which is conected to a V130. The person who wrote the program is unreachable and he didnt leave any comments in the program. At least there is a subrutine named Scada. At the begining of the subroutine is this piece of program that I don't understand what it does (see attachment). If someone can explain me what is going on there I would be greatefull. Thank You. Best Regards. Quote Link to comment Share on other sites More sharing options...
