I've managed to run Ladder logic code on a virtual PLC running on my laptop. Now, I want to connect to a device over EthernetIP, but I always get the "No driver found" message. Can anyone shed me some light?

Try OSCAT_BASIC and Function DW_TO_REAL. DWORD_OF_BYTE my although help. The Lib is open and free. It is not necessary to add this Lib, you can use/copy the source code just to get an idea.

Hi Jinlee, how are you? I have similar application requirements on my project. I have tried dynamic mapping, but the code cannot detect the IO module change when I did hot switch. Do you find the way of how to identify the module change dynamicly? Thanks.

Post by totorovic on Hard shutdown: no code on device after power on ^{CODESYS Forge talk (Post)}
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.

Post by totorovic on Hard shutdown: no code on device after power on ^{CODESYS Forge talk (Post)}
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.

I know it's been a while, but I did find this: system.commands['staticanalysis','config'].execute() It opens the UI to select your settings, but I haven't figured out how to load the .CSA yet.

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.
