Post by eschwellinger on NO SIGNAL ON POWER_ON FOR STEPPER MOTOR ^{CODESYS Forge talk (Post)}
Hi, how should that work? You need to download the example project and you need that structure of the project and one of the additional hardware sets https://forge.codesys.com/drv/sm3raspistepper/home/Home/ L298N or A4988, DRV8880. Important to have no GPIO in the project and have this additional tasks.

Hi! thanks for reply. We tested the configuration you proposed as well; however, when the cable between the controller and the switch was disconnected, the Active and Standby roles were swapped. Did you observe the same behavior in your configuration using WAGO and Beckhoff?

Post by jeffgamsby on Accessing ModbusTCP addresses from python ^{CODESYS Forge talk (Post)}
Hi, I am new to modbusTCP and I am trying to access Input registers from codesys (3.5.SP13). The offset is 16#0000 and I am trying to access Channel 1[24] %IW24 to pull analog values. I am using pyModbusTCP and I need to supply a modbus address and the number of registers to read. What does 16#0000 mean in terms of the actual offset, how do I translate this number plus the channel to access this info via python? Any help would be appreciated, thank you.

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 srouse on PFC200BUS not running ^{CODESYS Forge talk (Post)}
I started a project in codesys for a WAGO 750-8212 PLC and I am working on getting online with the controller. I can log in to the controller and I can see and control all of the fieldbus couplers that I have. I am unable to get the internal bus working. It just says that the bus is not running and when I scan or devices nothing shows up. Am I missing something important in my device tree?

Post by spilin on All devices lost for all installed version ^{CODESYS Forge talk (Post)}
hello. After installing the latest version of codesys (3.5.20) from codesys installer, I had a problem. All my devices disappeared. Both PLCs and IO modules and network devices disappeared from my list. I browsed through the Windows files and I can find them in the programdata/codesys/devices folder. The files remain there, but they are not available within codesys (same error in all installed versions) which in this case are 3.5.16 and 3.5.19. Does anyone know how I can reimport or resynchronize my devices folder again? Thanks

Post by johnbomb on Ignore Dependencies When Loading Package? ^{CODESYS Forge talk (Post)}
I'm trying to load a .package into Codesys 3.5.21, but the package is intended to only work with Codesys 3.5.18.0 and is configured with dependencies on the specific versions of other packages included with 3.5.18.0, and 21 has newer versions so the package will not install. I would like to install the package anyway to try and get things working on a newer Codesys version, since for some reason the installer for .18 errors out and doesn't fully work in my environment, but .21 seems to work fine.
