Questions tagged [s7-1200]

This is a tag to identify Siemens plc's from the product line S7-1200 series.

Questions related to the S7-1200 line may include module setup, function, errors, OPC communication but also communication via for example the snap7 library.

Some issues you may post are related to older PLC firmware versions in combination with certain Tia-Portal versions. If this applies to your case include version numbers always in the question either upfront or after the issue is solved. This way you save other users a lot of time finding bugs that are user coding unrelated.
