Hello thequark; The best and most immediatesource of information for programming laguages (and most S7 questions) is always the Siemens manual on the subject. Here is a link to the S7-SCL manua, in case you do not have it, or cannot have access to the SCL online helpl: http://support.automation.siemens.com/WW/view/en/5581793 A little bit of reading will bring you to this statement: 12.3 Calling Functions and Function Blocks 12.3.1 Call and Parameter Transfer Calling FCs and FBs To make it easier to read and update user programs, the functions of the program are divided into smaller individual tasks that are performed by function blocks (FBs) and functions (FCs). You can call other FCs and FBs from within an SCL block. You can call the following blocks: • Function blocks and functions created in SCL • Function blocks and functions created in other STEP 7 languages (LAD, FBD, STL) • System functions (SFCs) and system function blocks (SFBs) available in the operating system of the CPU. Technical details and parameter calling detailsfollow in the same chapter. Hope this helps, Daniel Chartier P.S. The manual is also available in Spanish, if this helps: https://support.automation.siemens.com/WW/llisapi.dll?aktprim=100&lang=es&referer=%2fWW%2f&func=cslib.cssearch&siteid=cseus&extranet=standard&viewreg=WW&groupid=4000003&objaction=cssearch&content=adsearch%2Fadsearch%2Easpx%3Ftab%3D2 D.C. |

Ok. I read the chapter thouroughly and I understand it now. I was thinking that it was more simply than a "Call" Intruction or seemed. Thanks for help. |
