Post by davidmic on What is this ST syntax? ^{CODESYS Forge talk (Post)}
I found some structured text code which contained this statement: bHidden:= TRUE(*NOT _somevariable*) I haven't seen TRUE() used like a function before, and I also haven't seen the enclosing asterisks * * before. What do they do? (sorry if this is a duplicate question, I don't know what words to use to search for this syntax)

Post by davidbo on Modbus: Is there a way to get the channel index from the channel name? ^{CODESYS Forge talk (Post)}
When I use the FUNCTION_BLOCK ModbusChannel I have to sepcify the integer iChannelIndex It can easily go wrong if one has many channels. It would be better if one could use the name. Is that possible? Attached a snippet of the channel name and the channel index to the left.

Post by dekelec on TrueType font problem ^{CODESYS Forge talk (Post)}
Initially I had the same problem in CoDeSys when selecting a newly installed TTF font, while CoDeSys was running. I solved it by closing Codesys and running it again to restart the initialization process. After that, using the new font did not pop up errors. I also had cases with files that had a ttf extension, but were actually not TrueType.

Post by pixsys on loading delay with the option "check client animations and overlay of native elements" ^{CODESYS Forge talk (Post)}
Hi, the option "Support client animations and overlay of native elements" needs a very powerful graphics accelerator in the system. I'm using the Pixsys srl "TC series" HMI with the code "P3" (so a 4+4 cores CPU) that runs very well also with this option active.

Nice puzzle for a Saturday afternoon :-). Here my suggestion: VAR sInput : STRING := 'R123'; byChar : BYTE; sOutput : STRING; i: INT; END_VAR sOutput := ''; IF LEN(sInput) = 0 THEN RETURN; END_IF FOR i := 0 TO LEN(sInput) - 1 DO byChar := sInput[i]; sOutput := Concat(sOutput, TO_STRING(byChar)); END_FOR

Post by bertcom on Converting each character to a string into ASCII ^{CODESYS Forge talk (Post)}
@TimvH, Thank you, i think this way i can seperate the complete string to characters. Next part of the topic is converting the characters to an ASCII code. Is there an standerd function in Codesys for this? I alredy searched a few hours for it on the internet. no succes.

Post by jeroenaero on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
I don't have a multiplexer so it very weird that it connects with that multiplexer. If i do a I2C scan on the PI terminal, i only get the device addresses 0x48 and 0x51. One for the ADC and one for RTC. I will try again with your libraries

I am definetly not an expert in this field, but it does seem like you need a propper API key in the URL. Right now you are using the token 'ANWB' in your URL, which the website returns an error, since this is not valid. Somehow you first need a propper API key. I hope that makes sense.

Hi all, I am using a unionn statement for merge in integer data type some values that are received in byte from the i/o cards, but, using this simple and light technique, is not recognized by the ethercat data exchange and in fact the tags are not updated. In my opinion it's a very big bug.

Thank you, very useful information. I did a library for serial communication and could not understand the reason only 256 chars could be read (after sending more than 256). Following your suggestion, I can now send any number of chars and everything will be received.
