Hi all, I have been using an S7-1200 along with the Wonderware DASSIDirect server to communicate with Wonderware Intouch. [schnippschnapp] A seperate problem, if I have a +/- 10V analog input signal I try and access for example IW96 it does some very strange things with the input goes below 0V. For 0-10V it goes from 0 to 32000 about, however when I go below 0V it jumps to 65500 and then goes down to about 33000. I am not sure if this a problem because the server cannot do signed integers? Thanks for any help in advance! Splitted from Problem with S7-1200 and DASSIDirect server. |
