If it is a BOOL, then use: ...Error_Active := ALARM BOOL: ALARM INT: STATE

Post by garrian on How to write multiple coils (Modbus FC15) ^{CODESYS Forge talk (Post)}
Thanks for your reply. I belive it is contiguous, I'm writing to adress 0 to 4. Or, do you mean something else? Well, something is happening. If I on the client set adress 1,2,3 to true, only 1 is set to true on the server side. On the client side, the data is array of word. But on the server side, the coils are array of bool. Holding register is array of word on server side. Can this be a problem? Attached screenshot of how it looks at the server side.

Maybe try going back to step one and: Var Reg1: WORD; Reg2: WORD; Reg12: DWORD; Value: REAL; end_var // program Reg1:= 4096; Reg2:= 14884; Reg12:= (reg2 * 65536) + reg1; Value:= DWORD_TO_REAL(Reg12);

you try to convert a WORD with BYTE_TO_HEX directly? Using https://de.helpme-codesys.com/ lead to the SM3_shared lib. There is a function: https://content.helpme-codesys.com/en/libs/SM3_Shared/Current/SM3_Shared/StringFormat/Word_To_HexString.html

Thanks! As far as I can see, the client can only send words. And on the server side there are an array for each of the functions: bool for coil and discrete, word for holding and input registers. I assume I can use holding register, then use bit mapping on the words instead of coils. But I really want to use the FC15/coils.

Any reason BIT and BOOL data types are not interchangeable? Trying to make a function which takes a BOOL IN/OUT parameter (Not allowed to use BIT) In the main logic if I make a DINT variable, and want to use each bit on different functions CODESYS will not allow it.

Memory addressing is measured in bytes, with BOOL occupying one byte. BIT is quite unique as it occupies one bit. So, try not to use BIT in the program. You can use the Unpack function to solve your problem.

Post by wiresplus on INT_TO_WORD function not working ^{CODESYS Forge talk (Post)}
Hello, I need to take an INT input, and convert it to a WORD value. VAR DRV2Speed : WORD; //IO card takes a WORD where 16000 = full 10V output (equivalent to 50Hz) PumpFillSpeed : INT; //Users enter a value between 0 and 50 END_VAR IF <conditions> THEN DRV2Speed :=INT_TO_WORD((PumpFillSpeed/50)*16000); END_IF </conditions> According to me this should work - but it stays at 0, no matter what. What am I doing wrong?
