Post by george32 on Learning ST in an object-oriented way. ^{CODESYS Forge talk (Post)}
Dear all, I am currently creating a program in the ST language. Because the program is starting to grow nicely I would like to switch to a more object-oriented way of programming. (Like for example in Python). By surfing the internet I found out that Function Blocks is the best method for this. Now I would like to delve further into this, with all the possibilities that Function Blocks have only I cannot find a clear course, explanation of what everything is around the function block thing and how to approach everything. I find the standard documentation around Function Blocks rather abstract and the examples are minimal. Therefore I am looking for a page/course/document explaining object oriented programming in Codesys (or other PLC programming environment). Do you have any recommendations on this?

the interpolation block does not start from the absolute value. It returns to zero even when writing to dLastWayPosX , Y , Z.

Post by felipemsgarcia on Axis EtherCAT address ^{CODESYS Forge talk (Post)}
Hello, Thank you for your answer. I'm afraid I was not clear on what I was trying to achieve. I'm trying to change parameters and command axes from inside a function block and the first thing that came to my mind was pass both the EtherCAT slave and axis to the function block (as image attached). But, I believe it's worse than just pass directly the EtherCAT slave address to the function block (is it???). However I was wondering if there was a way to get the EtherCAT address directly from the axis, so I don't need to pass the EtherCAT slave nor the EtherCAT address to the function block. Thank you again!

Post by jonathan1321351 on IO-Link write parameters Ethernet/IP ^{CODESYS Forge talk (Post)}
I want to read and write parameters of an IO-Link device using acyclic messages. I have a Cube67+ in Ethernet/IP, connected to an IO-Link master. In the datasheet, I can find the parameters required for the message (Service, Class, Instance, etc.). I see the function block "Set_attribute_single" in the "EthernetIP Services" library, but I'm not sure how to correctly send the index and sub-index for the IO-Link device. The class in the datasheet is 0x80 for the IO-Link Parameter Object, but it’s not present in the CPIClass enum. Is there another function block more suitable for configuring IO-Link devices? (similar to "iol_call" in PROFINET or what’s used in EtherCAT).

Hello all, Can someone point me to the OMAC PackML State Machine library documentation, I can't find any description of the block functionality ? I was looking into https://content.helpme-codesys.com/en/libs/index.html but there's no PackML there. I'm new to Codesys and don't know if I'm doing something wrong here ? In library tab in codesys whenever I want to see documentation I'm getting an error. Regards Bart

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! :)
