When you want to call an FB inside another FB , use multi-instance with address access related to that. Calling an FB inside an FC is possible, directly by assigning an IDB or manipulating elements inside of IDB. Some templates can be found in the following manuals: unknown user The following manuals will help you to start and develop your programming skills in structured control language. S7-SCL V5.3 for S7-300/400 Getting Started S7-SCL V5.3 for S7-300/400 Structured Control Language (SCL V4, V5.0) for S7-300/S7-400 Programming Also check this reference for SCL section Automating with STEP 7 in STL and SCL and sample codes which can be downloaded free of charge from here: Automating with STEP 7 in STL and SCL README.TXT PDF Programming Examples "SCL-Book" ZIP And finally , this link will be added as visual Demonstration: The High-Level Language S7-SCL I hope this helps, hdhosseini
