Well, both have sequential logic, based on steps and transitions. S7-Graph is more focused on step 7 programs, but SFC for PCS7 is easier to handle because it has interaction with CFC (Continuous Function Chart). With this combination, configuring steps and transitions is much easier and faster. An SFC also has a message system which you can use to generate alarms/warnings. Basically, SFC is used for bulk engineering, thus integrated in PCS7. However, SFC is also available for S7 programs. With SFC's you have two types: SFC chart and SFC type. You can use a SFC type for example when you have 10 tanks with the same functionality. You create one SFC type and you can use 10 instances of that SFC type. You only have to configure one SFC type. SFC type is mainly used with PCS7 Batch. It has a clear interaction with Batch, so Batch can control the SFC type. There are more differences between S7-Graph and SFC, but basically SFC provides more options and possibilities. |
