Post by pietrobalint on Retain / Persistent Variables in Codesys for Raspberry Pi ^{CODESYS Forge talk (Post)}
If I select "Update boot aplication" while I download the code the persistent variables got a constant startup value. But during the running I am still not able make the persistent variables to hold they actual value.

Hi! I have a problem, when I write Ethernet.Enable, I get an error ("Enable" undefined). Could you send me the program? I can't solve it, and I don't know if it's because I'm missing a library or some FB...

I think that the .err file is the .app file renamed by Codesys, so it is compiled. We met this behaviour one time, it was because the runtime goes in exception due to bad Ethercat cables.

Hi, Runtime goes in exception before the shutdown ? Do you have a .err file which is created ? (located in the folder of the .app and .crc)

Post by egau on Hard shutdown: no code on device after power on ^{CODESYS Forge talk (Post)}
This explanation aligns with the issues we’re experiencing with our machines. The scenario I described is happening with one of them (let’s call it Machine A). This machine is identical to another one (Machine B), except for some custom code that facilitates communication with an external Beckhoff PLC for MES integration in the production line. Machine B has been powered on and off daily for at least three months and has never had this problem. Given that, I highly doubt the MES custom code is the cause of the code corruption. This being said, your explanation does seem plausible. However, if faulty EtherCAT cables were the issue, why wouldn't the error occur during normal operation? Why would bad cables only cause problems during a hard shutdown? One last question: When you encountered this behavior, did you see a similar error in your logs? i.e, an "AccessViolation" exception in the EtherCAT Task?

That time it was not answered. But yes, it is possible. Search for "Relative movement" properties of the rectangle element. Might need to enable advanced features in the property browser. https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_elem_rectangle.html

That works, thanks, I was trying to get a variable into the Position>Height and was struggling, then I was using absolute movement, never though to try relative movement.

Post by bertcom on STRING conversions to DWORD ^{CODESYS Forge talk (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!

For a permanent change, you may need to update the PLC configuration file or set the IP at startup using retained variables.

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).:-(

Hi, unfortunately, in Softmotion you have only access to the combined fraction - the scaling factor from user units to motor increments. It can be accessed using MC_ReadParameter with parameter number 1054. increments = user_unit_position * fScaleFactor

Post by chalk on No source code available ^{CODESYS Forge talk (Post)}
Hello, This is my first time using Codesys, I am trying to add EtherNetIP communication to a Raspberry PI. I’ve added the EtherNetIP Adapter configured the network setting and added some modules to the pi but when I download the project it generates the following error: “There is no source code available for the object because it is in the compiled library ‘cip object, 4.5.1.0 (3s – smart software solution gmbh)’. Do you want to browse for the original library in order to display the source code? There are 2 errors in the log which are: SOURCEPOSITION App=[Application] area=3, offset=332760 EXCEPTION [Application] occurred: App=[Application], Task=[ENIPAdapterServiceTask] I can’t for the life of me work out how to get around this. I can’t find the source code anywhere or any information regarding this error. I’m using Codesys V3.5 SP19 Patch 3, the version of the Ethernet adapter is 4.5.1.0 and the version of the modules is 4.1.0.0. Any help on this will be greatly appreciated. Thanks
