Post by joep on Custom robotics kinematics model debugging ^{CODESYS Forge talk (Post)}
When trying to move my axis using any group move instruction I get the following error: SMC_CP_INVALID_PATH_ELEM and axisgroup goes into errorstop state. I tested my methods thoroughly which makes it hard for me to debug. Are there some hidden rules I need to abide to? How would one go about debugging a custom robotics model, since the information inside isn't accesible. Is it possible to find the source of where the function breaks? Any hint in the right direction would be appreciated. Best regards

Post by anderson on function block output ^{CODESYS Forge talk (Post)}
I'm trying to make a CNC machine, but I'm having problems because the drive I'm using only has the option of communicating through digital inputs. In this case, I should use the CLP's digital outputs to communicate with it, correct? However, in the function blocks it seems that they are already pre-programmed and I didn't find the pulse output options, for example, so that I could associate a digital output from the PLC to connect this to the drive's pulse input. My question is: is it possible to associate the pulse output of the function block with a digital output of the PLC? and how to do this?

Post by voffi on Converting UINT into bytes and converting 2Bytes into UINT ^{CODESYS Forge talk (Post)}
There are some ways. One is to use SHR and SHL and it depends on your byte order in the data array. For Motorola byte order: PROGRAM PLC_PRG VAR u : UINT; byte_array_in : ARRAY [1..8] OF BYTE := [16#11, 16#12, 16#13, 16#14, 16#15, 16#16, 16#17]; byte_array_out : ARRAY [1..8] OF BYTE; END_VAR u := SHL(TO_UINT(byte_array_in[2]), 8) + TO_UINT(byte_array_in[1]); byte_array_out[1] := TO_BYTE(u); byte_array_out[2] := TO_BYTE(SHR(u, 8)); If it's Intel byte order just change 1 and 2 in the array indexes.

Post by matthew on New Ladder Diagram conversion does not work due to missing features ^{CODESYS Forge talk (Post)}
Hi It looks like in the new ladder there is no way to remove unused FB call parameters or update the function block? It's quite often where you have a function block with multiple uses and not all the parameters are required. Need the ability to leave an input/output blank without getting an compile error Expression expected instead of '' Also double clicking on the FB no longer opens the underlying FB code and view what it was doing online. Dragging and dropping a variable does not work, only using the selection works. Will these be available in the V1.0 release or just best to stick to the old ladder until it's available? Thanks
