Hello, If you look at the details you can see Simatic is the Author, these are FB's from the Library and intended not to be read, you don't need to read them(don't want to in most cases too) All these blocks reveal their secrets by pressing F1. Have attached the Cont_C help in pdf Regards, Marcjan AttachmentPrinting _Continuous Control with SFB 41_FB 41 _CONT_C_.pdf (362 Downloads) |

Dear algudkar, As the last suggestion, if you have access to SCL editor you can compiles these codes and check the result.No protection utilized here: [code]FUNCTION_BLOCK FB100 // Block Parameters VAR_INPUT // Input Parameters ein1:BOOL; ein2:BOOL; END_VAR VAR_OUTPUT // Output Parameters aus:BOOL; END_VAR aus:= ein1 AND ein2 ; // Statement Section ; END_FUNCTION_BLOCK [/code] In this section only add "KNOW_HOW_PROTECT" to your code as shown and compile the FB.Delete the SCL SOURCE file from "sources" folder and now try to open FB100.This is the case you may encounter with FB41.Block was protected and no access to the source file. [code] FUNCTION_BLOCK FB100 KNOW_HOW_PROTECT // Block Parameters VAR_INPUT // Input Parameters ein1:BOOL; ein2:BOOL; END_VAR VAR_OUTPUT // Output Parameters aus:BOOL; END_VAR aus:= ein1 AND ein2 ; // Statement Section ; END_FUNCTION_BLOCK [/code] See the attachment for 2 snapshots.
