pbPayload is a pointer, which it expects to point at a STRING. If you point it at an address holding a different data type, it will just assume those bytes are part of a string and likely trundle along memory until it finds a null byte (0x00) that would normally signify the end of a string PublishMessage := BOOL_TO_STRING(boolVariable);

Post by janber on REFERENCE TO in an array ^{CODESYS Forge talk (Post)}
Hi all, in the online help it written, that array of reference to data type is not possible. Ok... but if I create array of struct of reference to - everything works fine - please see the screenshots: and it works this way OK. Is it intention or error in compiler 3.5.18.20 and we should avoid it? Thanks a lot, Jan.

Post by alexgooi on Modbus writing on value change ^{CODESYS Forge talk (Post)}
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.

Post by remcoborghuis on C0032 Error to type Pointer to IoConfigParameter ^{CODESYS Forge talk (Post)}
Hi All, I'm using codesys on a raspberry PI. I use V3.5 SP18 Patch 2 development system and codesys for raspberry pi 4.8.0.0. Sometimes when I build the project I get error messages C0007: Expression expected instead of ',' and C0032: Cannot convert type 'Unknow type: '!!!'ERROR'!!!" to type 'POINTER TO IoConfigParameter'. I can't click on the message to bring me to the fault. After I do a "Clean all" the build finishes successful. Anyone who can help me with this problem? Thanks! Remco Borghuis

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hallo, I have a strange problem with the recipe manager. ISSUE: When using RecipeManCommands not all values are loaded correctly. Saving a recipe with CreateRecipe(), ReadAndSaveRecipe() or ReadAndSaveRecipeAs() works without any problems. BUT: LoadRecipe(), WriteRecipe() or LoadFromAndWriteRecipe() do not load the data correctly. It is Interesting that we have a different error pattern with LoadRecipe() than with WriteRecipe() or LoadFromAndWriteRecipe(). LoadRecipe() does not load all data and WriteRecipe() or LoadFromAndWriteRecipe() overwrites some data or assigns it incorrectly. And it is also strange that LoadRecipe() writes the values to the PLC. Normally it doesn’t do it. It makes no difference whether the memory type is textual or binary. I have an object consisting of STRUCTs which is inserted in the recipe definition. Environment: Codesys V3.5 SP19 Patch 4 (64Bit), Recipe Management 4.2.0.0 *Add a project (reduced to the problem)

Thanks for the update, Since you can't double click is there another way to enter the FB when online and see the running code of that instance? When can we expect to see v1.0?

thank you, i tried your library and device description but i don't get analog values. Do i something wrong? i also got an library error at the I2C_BASE functionblock the calcCycleTime gave an variable size error, so i added thet conversion from ULINT_TO_UDINT.

Post by sumit on Not able to see input data coming from eip adapter on codesys ^{CODESYS Forge talk (Post)}
Hello there, I have an eip adapter running (remotely) that is sending data back to eip scanner (running on codesys). I can send data from scanner (codesys) to the adapter but not getting the data back from the adapter. I have verified the incoming data on wireshark but I don't see this data in the codesys. I have tried local variable mapping and global variable mapping not variable values just stays at 0. Please guide.

Post by duvanmoreno24 on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Yes, I tried to do what you put in the first code. However, I have a problem with that and that is that the inputs must be declared with the type. I have many data types running in my code (real, int, uint, bool) and I can't put them in the same function, another thing is that I need to instantiate that function for everything I want to write to the slave. You put a for to 200 but it means that it has to be the same data type and inside the array, but I want to get them individually. I'm struggling to do it in a good and efficient way like wago's E-cockpit does. in the first screenshot you can see, you simply type in value, change the package of things you want to write in value change and it does everything by itself automatically, without comparing any old and new values and even less having the need to activate a bool. , it is perfect.

Post by egret on Issue with J1939, PGN 65267 (Vehicle Position) ^{CODESYS Forge talk (Post)}
I have a J1939 network (ISOBUS) connected to my PLC. I can receive various PGNs such as 65256 (Vehicle Direction/Speed) and 65254 (Time/Date). However, I cannot receive 65267 (Vehicle Position). PGN 65267 (VP) contains SPN 584 (Latitude) and SPN 585 (Longitude). On the network both SPNs return a value of -210 (meaning the CAN message payload is zero in both cases). The conversion settings are the default values and appear to be correct (see attached screenshot). Using a CAN analyser I can see that PGN 65267 (Vehicle Position) is being transmitted over the network with valid (non-zero) data that matches the latitude and longitude coordinates I would expect. I've created a program to read the raw J1939 data and this also returns valid data. It seems that the Codesys J1939 database has a problem with reading PGN 65267 messages. Can anybody else confirm this? I'm using Codesys Version 3.5 SP16 Patch 5.
