First off, thanks for the patience with my post. Rookie to Siemens. I am trying to use a Retentive timer and it has to be around 24hours. Thus I found using the S_ODTS does not work because of its datatype limitations. I then explored trying to use SFB4 and it appears to work as a TON but not retentive. So through google I then found "FC80" which appears to do what I need but am not sure how to drop this into my S7 300 series processor (if its even possible). Its greyed out when I right click on FC Blocks then Install block.
I can do some move commands and the such to retain the value using the SFB4 which is the current path forward. Any tips on if/how to drop in the FC80 or some other FC/etc to make this work?
