Hi!, Nice question. I already responded to a topic discussing SFC type/charts-> SFC types vs SFC charts. Good to mention: Since V9.0 it is possible to use EMT/EPHT. This is a type just like a CMT (Control Module Type), but with addition that a SFC type is always inserted. When you're done, you can create EM's and EPH's (instances) in your project using copy paste or using Plant Automation Accelerator. Using them is highly suggested, because when changing the EMT (Type), all instances are synchronized. Above the EMT is a EPHT which you can control multiple EMT's and/or CMT. To get a better impressing, you can check the following manual as of page 73: PCS7 Compendium Part C-Equipment Phases with SFC Types (V9.0) In short, you create a CMT (A Valve with some logic like interlocks and driver blocks), you create commands (SetAuto) and status (IsAuto) in the CMT using the block contacts and you use those commands/status in a EMT (SFC). In a EMT you can insert the CMT as template and assign roles like Fill/Empty. You can give commands/status using technological IO in the EMT which is basically controlling the role object. In a step you can give command: Fill.SetAuto. When instancing in the project, you simply assign the CM's to the roles and all connections are made automatically.
