Post by shamcke on Array with generic constant as persistent variable ^{CODESYS Forge talk (Post)}
Hello, I have written a function block that uses a generic constant for the upper bound of an array. I wanted to have this array in the persistent memory area, thus I constructed my FB as follows: FUNCTION_BLOCK FbWithGenericArrayLength VAR_GENERIC CONSTANT uiArrayLength : UINT := 10; END_VAR VAR PERSISTENT arr : ARRAY[1..uiArrayLength] OF INT; END_VAR In my PLC_PRG I declare an instance of said FB PROGRAM PLC_PRG VAR myFb : FbWithGenericArrayLength<10>; END_VAR This compiles just fine. When I let CODESYS fill my persistent list, it adds duplicate entries {attribute 'qualified_only'} VAR_GLOBAL PERSISTENT RETAIN // Generated instance path of persistent variable PLC_PRG.myFb.arr: ARRAY [1..uiArrayLength] OF INT; // Generated instance path of persistent variable PLC_PRG.myFb.arr: ARRAY [1..uiArrayLength] OF INT; END_VAR so I manually delete the duplicate. When i now compile, I get errors ------ Build started: Application: Device.Sim.Device.Application ------- Typify code... [ERROR] Sandbox_FW31: PersistentVars [Device: PLC Logic: Application](Line 4): C0161: Border 'uiArrayLength' of array is no constant value [ERROR] Sandbox_FW31: PersistentVars [Device: PLC Logic: Application](Line 4): Type of mapped variable is not equal to original type Compile complete -- 2 errors, 0 warnings Build complete -- 2 errors, 0 warnings : No download possible Is is simply not possible to use a generic constant for the persistent array? Thanks in advance. Edit: It seems I can manually replace the uiArrayLength in the persisten list by the value 10 I used as the generic constant for this particular instance.

The green icon with an ! next to the device is concerning. Is the data type correct for the input, you are using a byte input but the description says string. Is there anything useful in the status tab?

You could create a DUT of the Type Union and add an array of 2 bytes + an Int. Then write the byte values in the array of the Union and read the Int. Or VAR iInt : INT; byHigh : BYTE := 2#1111_1111; byLow : BYTE := 2#1111_1111; END_VAR iInt := TO_INT(byHigh*16#100 + byLow);
