Hello, I tried installing ControlWin 3.5.20.40 and still have the same issue. I tried on 2 different PCs running Win10 Enterprise 2016 LTSB So I then installed the Gateway from 3.5.20.20 and it works. Is there an issue using ControlWin 3.5.20.40 with Gateway from 3.5.20.20? Thank you

Hi, again after spending a lot of time finding more information with no results, by chance I changed the device ID from 1 to 255 and the transmission works. Unfortunately the documentation is very very poor.

Is it possible to change the variable being traced during runtime? I would like to use the CURRENTCLIENTID in combination with an array of real numbers to alter the traced variable in a display window, without needing to create separate visualizations for each variable.

to get the address just use ADR( ) variables defined in a VAR_IN_OUT block are references pointing to the passed variables. VAR_IN_OUT MyVar: bool; END_VAR VAR adrMyVar: __XWORD; END_VAR adrMyVar := ADR(MyVar);

Post by bertcom on STRING conversions to DWORD
CODESYS Forge

(Post)
Good afternoon. I want to communicate with a Domino Industrial Printer using its Codenet protocol. The printer wants a series of Hexadecimal characters with no spaces or '00' characters. Because of that i chose the option to make the prefix and subfix for my code in a string. I have variable data in another string. With a complete program of a lot of CONCAT functions i eventually get the format of code that the printer accepts ( tested it with the hercules tool). Hercules String : 1B4F513030311B7532626C61636B04 The problem is : Codesys adds automatically 'code' to the code to show it is a string. Codesys string : '1B4F513030311B7532626C61636B04' The printer does not understand this. My idea is to convert the string datatype to an LWORD. I have no idea how to do this. I random types in STRING_TO_DWORD, as return i get 0. That didn't worked. Also on internet the explenations around string converting in codesys are very limited. If there in anyone who can explain me how to do it, i would appreciate it a lot ! Thank you!

I haven't actually found an answer yet. It happens quite rarely, so testing and diagnostics are complicated. I've updated the software with every SP and add-on updates released, but it's probably a Kernel driver issue.

Thank you, Bingo. Your idea of adding the change to the start up process works. However, I am still intrigued with the fact that SysSockSetIPAddress(strEthernetPort:= '0', strIPAddress:= '192.168.2.12') is different from PLC Shell (setipaddr 0 192.168.2.12).:-(

Hello SDO will write to the drive, not the axis, so you need to pass in the ethercat slave: VAR_IN_OUT Axis: IoDrvEthercatLib.ETCSlave; END_VAR Then you can get the address with: Axis.PhysSlaveAddr (as UINT)

Are these variables already declared in the IO list? It looks like it's trying to create new variables instead of mapping them to the existing ones.

Arrays with variable lengths are a bad idea. This makes your system unstable and can lead to crashes. Declare your array large enough to reserve enough memory

You can use function blocks like TCPServer to start the Retro Bowl College server and TCPAccept to handle incoming connections, with CAA.Handle simply acting as a reference ID for each resource.

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.
