      In simulation mode there are no fieldbus updates possible - so this makes only sense with real devices.

      The way I usally tackle this is by syncing only words (then you are able to use the FB above). If you then want to write a Boolean simply type it like this. Value[1].0 := Bool1; Value[1].1 := Bool2; Value[1].2 := Bool3; Uints have the same number of bits than a INT/WORD so these ones will work as well (they are only represented diffrently). A Real will work but you will loose some infomration in the conversion. If you want to keep the information you can convert 2 words to a float with a function (for example with the IEEE-754 standard) . In this way the syncing to the server is very simple and in the Codesys Program you decide what part of the word you want to use.

      Hi all I want to pass a struct into a function without declaring the struct in a VAR/END_VAR. Is this possible? I think this would be called a struct literal It would look something like this someFB.write(structArgument := MyStruct#(a := 1, b := 1.2), otherArgument := TRUE); With this struct declaration TYPE MyStruct : STRUCT a : INT; b : REAL; END_STRUCT END_TYPE

      Hi, we did install the real-time kernel patch on the RPI and also performed the additional optimizations including isolating the cores. Changing the configuration of the planning task e.g. running it on a separate core, changing the cycle times and mode from cyclic to freewheeling did not show any improvements.

To search for an exact phrase, put it in quotes.  Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it.  Example: docs -help
To search on specific fields, use these field names instead of a general text search.  You can group with AND or OR.
