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 don't fully understand the issue, but if the encoding is a problem you can try testing with WSTRING datatype instead of STRING. https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_datatype_wstring.html

@trusty-suire, The problem is not encoding. The problem is that codesys ands ' ' to the string. And the printer can't handle these character.

Guten Morgen, ich habe ein Problem mit dem Lesen von IO Link Geräten. Wir nutzen einen Festo IO-Link Master den ich mittels der Funktionen ETC_ADS_IoLinkRead und ETC_ADS_IoLinkWrite lesen und schreiben möchte. Dazu implementiere ich die Bibliothek EtherCATStackLibrary 4.6.1.0. Hier geht schon das erste Problem los. Diese Bibltiothek möchte eine weitere Bibliothek nutzen, die "CmpSysEthernet". Diese muss ich über die Platzhalter manuell auf "SysEthernet 3.5.19.0" linken. Dann sind erstmal keine Fehler mehr vorhanden und das Projekt lässt sich übersetzen. Beim oder vor dem laden in die (Eckelmann) Steuerung, bekomme ich dann aber Fehler über unaufgelöste Referenzen, über Funktionen aus der SysEthernet Bibliothek (siehe Screenshot). Hat da jemand eine Idee oder Lösung?

Hi, The '' characters in Codesys are there only to indicate it is a STRING type. They are not actually added to the string, maybe you are adding them unintentionally in the concat function? You can send your data from Codesys to Hercules to verify... Another option is to send the data as an array of bytes instead of a string, with every byte representing 1 ASCII character. https://www.ascii-code.com/ This way you are 100% sure Codesys is not adding any unwanted characters.

I guess that the printer expects to receive an array of byte values. So where it is described that it expects to receive: Hercules String : 1B4F513030311B7532626C61636B04 it actually expects to receive an array of bytes with the values 1B,4F,51,30,30, etc. So what you can do is create an array of bytes and assign the byte value to each item in the array: VAR abyToSend : ARRAY[0..99] OF BYTE; END_VAR abyToSend[0] := 16#1B; // ASCII Escape character, hexadecimal representation uses 16# as prefix abyToSend[1] := 16#4F; // ASCII 'O' abyToSend[2] := 16#51; // ASCII 'Q' abyToSend[3] := 16#30; // ASCII '0' // you can do the rest yourself // maybe could be created a lot smarter, but gives you an indication how to handle this. Then with the serial communication (or TCP/IP?) you can send a message with the reference to the array (abyToSend) and the number of bytes to send (15 bytes for the string you gave as example).

WHEREAS, I have already searched various posts and forums, where mostly there are few references and mostly geared toward integration in TwinCAT. I am looking for how to properly configure the EL6731 board as a DP master, (where I have its 3S license), with CoDeSys 3.5.19.x. I have three types of slaves, all integrated with their GSD descriptors. In the tab for the various slaves, I don't see options related to node restart on 'station return'. On the card manual, I read that for each slave I should be able to configure parameter 8000:2C: “8000:2C Restart behavior after DP fault Reserve, must be 0 BIT1 RW 0x00 (0dec)” However, in the project I see no way to configure this parameter, in any of the boards; and the arrays do not always have such an extensive size; most of the time they are only two or three words in size. The problem is that, after the hot reset of CoDeSys, the master restarts by starting all slave nodes, but if one or more get lost and go offline, there is then no automatic restart upon their return. I would need to figure out any solution, even via software, how to figure out that this one is back available and restart it.

The problem is looking for a bug somewhere in CoDeSys in that, when the slave returns, the cyclic data exchange resumes, but the diagnostics do not update and the node continues to resulting off-line. it is not a problem with the PB master, but with its 3S/CoDeSys management. CoDeSys 3.5.19.20 runtime. Any ideas on how to fix it? Thank you.

I encountered the same problem. (Windows10 x64 single language OS). As @eschwellinger mentioned, I uninstalled the latest EdgeGateway version and installed version 3.5.20.0. Now, when I right-click and select "Allow Edge Gateway...", Config mode is activated without any error or warning window and I do not need to manually type [CmpEdgeGateway] for EdgeGateway version 3.5.20.0.

Hello, In an example scenario like below figure, can the developer in City-A connect to the device in City-B remotely using only "Codesys Automation Server" and "Edge Gateway" with the following structure? If no, what should be done with Automation Server for this remote connection requirement? If yes, how should it be configured for this remote connection requirement? Thank you in advance for your answers. Regards, Imdat

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.

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.
