Industrial control programs are like a constantly revised “operation manual”. Today, the motor start logic is modified, tomorrow the temperature control parameters are adjusted, and the day after, new safety interlocks are added. Without version management, it is as frustrating as searching for books in a library without a catalog. The S7-1200, through TIA Portal’s … Read more
