Post by rossanoparis on After un upgrade of "CODESYS Control for Raspberry Pi MC SL" from v4.7 to v4.9 SysFileOpen function stopped working ^{CODESYS Forge talk (Post)}
Hello at all. After un upgrade of "CODESYS Control for Raspberry Pi MC SL" from v4.7 to v4.9 SysFileOpen function stopped working. I'm not able to read or write files from the PLC application. Before this upgrade all worked fine. I've read this thread [ https://forge.codesys.com/forge/talk/Engineering/thread/3da9ded84e/ ] Despite I followed that indications I couldn't get my code working again. Perhaps I'm missing something or I didn't understand how to use placeholders at all. Is there a different syntax to use for "SysFileOpen" in order to use placeholders? Thanks in advance for your help. Information Compiler: CODESYS V3.5 SP19 Patch 2 Runtime: codesyscontrol 4.9.0 HW: KUNBUS RevPi Connect S Below the paths I want to access (The entire CODESYSControl_User.cfg file is attached) [SysFile] PlaceholderFilePath.1=/home/pi/hpca/bin, $hpcabin$ PlaceholderFilePath.2=/home/pi/hpca/cfg, $hpcacfg$ PlaceholderFilePath.3=/home/pi/hpca/logs, $hpcalogs$ PlaceholderFilePath.4=/home/pi/hpca/resources, $hpcares$

is there a way to check the plclog on Opus A3 by using cmd line under Linux? This log is what you need to check for the disconnection problem

Thank you for the return. The path targets to a CFast card. User has R/W access to it. We will try to change it.

Post by felipemsgarcia on EtherCAT - Force Control Word ^{CODESYS Forge talk (Post)}
What worked for me: Use SMC_SetControllerMode and set the nControllerMode to SMC_nocontrol. With that, you can control the drive via Modes of Operation(16#6060) and Controlword(16#6040) directly. Hope that helps, Cheers!

Hi, I am looking for a way to define a local variable that will be multi user independent. This is so several user can connect at the same time select frames independent of each other.

Post by danwoodlock on RPI Zero w - Edge gateway cant install ^{CODESYS Forge talk (Post)}
I believe the reason that I eventually lose my ability connect is because of exceeding the time limit for demo mode. Still unsure why I cannot update the edge gateway though.
