SCL Array of Struct?

[Guest siemensPLC]

Is it possible to make an array of a self defined struct in Siemens SCL? I made the struct in a DB. The struct contains some history data of my installation... I want to define an array of 50 containing this struct. Ex: Values - Struct Limit - REAL Max - INT Time - DT END_STRUCT History ARRAY[1..50] OF Values I know that it is possible in C++, but is it also possible in LAD/STL/FBD or SCL? Regards

I dont know SCL, but in s7-manager you can do UDT-structs and use them in DBs as in C++. Key-Word is UDT. :*-( Edited 20 Mar 2004 by Seppo Alanen

UDTs can be defined in SCL as well.

Yes it is possible in Siemens SCL? You made the struct in a DB. The struct contains your data this is your DB example DB10 Before you create UDT example 10 (Create new Source.File) Source1.File // Make Your UDT10 Type UDT10 Structur Limit : REAL; // Limit of your Device Max : INT; // Max Value Time : S5Time; // data Time for your use End_Structur // Make Your UDT11 Type UDT11 Structur Device: INT; // Number of Device Param: Array[1..50] of UDT10; // Structur of your Parameters End_Structur // Make Your DB10 Data_Block DB10 UDT11 Begin Source2.File FUNCTION_BLOCK FCB10 Title = 'Test' // Test for this Example // // Version : '1.0' Author : 'HenonR' Name : Test Family : Examp VAR_INPUT Point1: INT; // Pointer 1st Element Point2: INT; // Pointer 2nd Element Block: UDT11; // data Block (Inser DB10) Param: INT; // Number of Parameter Device: INT; // Number of Device Limit: REAL; // Limit Value END_VAR VAR_OUTPUT MAX: REAL; // Max value END_VAR BEGIN MAX := Block.Param[Point1].Max; Block.Device := Device; Block.Param[10].Limit := Limit; END_FUNCTION_BLOCK This is a Example for Insert Input (Block) you use an other FC or FB in SCL, because in KOP,FUP,AWL is very Hard. FUNCTION FC11: REAL BEGIN FB10,DB20 ( Point1:= 1 ,Point2:= 2 ,Block:= DB10 ,Param:= 3 ,Device:= 1 ,Limit := 0.768 , MD100 := MAX); FC11 := MAX; // RETURN Value of Function FC11 OK := True; END_FUNCTION
