Post by ivan-g on MODBUS ^{CODESYS Forge talk (Post)}
Hi There, I took over a project from a colleague (in GTB) who left the company. When I took over his project, it wouldn't compile because some libraries were missing. I managed to recover quite a few libraries, but I can't find the library that contains the block functions shown in the image. Here are a few examples: Fb_RegMel_ISO Fb_DefModbus FbDecalConsSalSO Fb_Autor_FreeCool_CTA_C I'm a little stuck at the moment, so if you see a Facebook post that speaks to you, don't hesitate to get in touch! Thank you in advance for your help.

Post by bmatlove on AXIS_REF_SM3 Error Codes? ^{CODESYS Forge talk (Post)}
I'm trying to firm up alarming of axis faults. Declutter the code and figure out what's what. Diving into it, I see the AXIS_REF_SM3 function block provides uiDriveInterfaceError and dwErrorId, but I can't find any significance of these further than Drive interface error number Parameter number: 1014 and Drive specific error identifier, parameter number: 1031, respectively. Is there some corresponding appendix I could use to decode these? Also, is there any relation to the Error ID (of type SMC_Error) of the MC POUs? MC_Jog, MC_Reset, MC_MoveRelative, etc? If so, are the above errors redundant? Thanks in advance.

Post by nz-dave on Custom library, ethernet/ip adaptor ^{CODESYS Forge talk (Post)}
Im Putting alot of my custom functions blocks into a library I have a EthernetIP VSD FB that i would like to get Status from the adaptor. EthernetIP_remote_adaptor.estate is one what i want to get. so anyone know how to point that to my function block? when i use the block i just want to have an input "Drive" that would point to the adaptor. like in softmotion when you just put the axis name in the FB to point the FB to a certain axis. Hope that makes sense, cheers

Post by amy123 on codesys mqtt publish serialization ^{CODESYS Forge talk (Post)}
Hello, I am using the CODESYS IIoT Libraries SL MQTT Publish. Does this publish block only support publishing STRINGS as a readable format? I can publish ENUM, STRUCT, BOOL; however, MQTT Explorer will only display strings. When I use Wireshark, I can see that it is publishing something, but it looks to be publishing a serialized version which is a bunch of 0s or random text. If so, is there any way to deserialize this information back into a readable format? See pictures, where I have a BOOL TRUE that gets published as 001. Then see where I publish a STRUCT and it's an incomprehensible combination of 0s - only the string variable is displayed. Or, is it expected that you convert everything to a string before publishing? Any help is greatly appreciated! :)

Post by starmaxou on How to download dependencies packages for CODESYS Control for Raspberry Pi SL ? ^{CODESYS Forge talk (Post)}
Hi everyone, I'm trying to install the CODESYS Control for Raspberry Pi SL package. The computer with CODESYS software is offline for security reasons. So, I downloaded the package on another computer and installed it manually. But this package has dependencies packages: CODESYS.Control SL Extension Package, V4.0.0.0 CODESYS.Control SL Deploy Tool, V4.10.0.0 As I said, the computer with CODESYS is offline. I cannot use the package installer to search for these packages. I did not find them in Codesys Store with another computer. Do you know where to find and download them? Thank you in advance for your help!

Post by brell on Automatic xExecute NBS.TCP_write ^{CODESYS Forge talk (Post)}
I've recently started experimenting with CODESYS for a project and am fairly new to it. I'm currently working with Function Block Diagrams (FBD) to set up TCP communication between a server and a client, where the client is implemented as a Python script. Once the communication is established, my connection status changes to True, which is the expected behavior. My challenge arises with the TCP write module, which requires the xEnable_write flag to toggle between True and False. If xEnable_write remains True, the module only performs a single write operation. To address this, I introduced a falling edge trigger (F_TRIG), expecting it to help in toggling xEnable_write and it does, However, I've encountered an issue where in the beginning after connxion established I need to manually set xEnable_write to True for the system to work as intended. I'm looking for a way to automate this process so that xEnable_write becomes True automatically upon establishing a connection . Initially, I tried setting xEnable_write to True from the start, but this approach didn't work well since it left the flag permanently True, preventing further toggling. I also experimented with using a TON timer, but I faced similar issues. I am seeking a solution that automatically toggles xEnable_write between True and False after a connection is established, ensuring continuous write operations without manual intervention. Any advice or guidance on how to achieve this would be greatly appreciated."

Post by smartcoco on Add visual background FB blocks. ^{CODESYS Forge talk (Post)}
Can you add a background FB block to the visualization page, and loop through this FB block when the page is in display mode. This FB block requires two more functions, one for executing when the page is displayed and the other for executing when the page is closed.

Post by krisj on ScriptEngine POU property Get and Set accessor. ^{CODESYS Forge talk (Post)}
Hey! I am trying to generate a function block with properties from a list with script engine. Codesys/ScriptEngine creates both the Get and the Set accessor. I cannot find a way to delete the Set method/accessor. Anyone encountered the same problem or have a solution for this? for prop_name, prop_type in list: property = pou.create_property(prop_name, prop_type) get = pou.find("Get", recursive=True)[i] get.textual_declaration.replace("") get.textual_implementation.replace(prop_name + " := " + struct_name + "." + prop_name + ";") set = pou.find("Set", recursive=True)[i] set.textual_declaration.replace("") set.textual_implementation.replace("") i += 1
