in your project, to access /var/opt/codesys/PlcLogic/my.file, use the string 'my.file' or '$$PlcLogic$$/my.file'

Thanks for your help. Seems like one of these libraries are the root cause indeed.

Post by jerry-sorrells on Find Function: Object reference not set to an instance of an object. ^{CODESYS Forge talk (Post)}
Build: CODESYS 3.5 SP19 Patch 1 (64-bit) Host OS: Windows 10 Target: Linux SL I have a project with programs in Structured Text and Ladder Diagram. When I try to use the Find function, it works for the Active Editor; however, when I try to use Find for the Entire Project, I get the error "Object reference not set to the instance of an object." I know what this error means in the context of the program, but I have no idea why the find function is returning this error. The variable I am searching does not matter: it happens with all variables. Any help with this will be greatly appreciated. I generally use the Find function quite often as I am developing and not having it is really slowing me down.

Post by macros8 on Alarm Management - latched variable represented as Text list ^{CODESYS Forge talk (Post)}
Hi, I haven´t noticed you put the comment here. I thing it´s a bit different. What I want is to have detail errors of technology in data type e.g. INT. This variable I would latch to the corresponding error msg but I would like to get it convert to text from the text list and not keep it in INT form. Example. Main error Valve Error: SubErrors 1 - Both sensors 2 - Not retracted in time 3 - Not pulled out in time In HMI Main error + latch SubErrors => "Valve Error: Both sensors" The benefit is that text lists are part of translation and can be easily manipulated. I know I can create whole string msg in PLC but then, it lose advantage of Alarm management. Thanks. M.

Post by tomgr on Codesys 3.5.19 Control Win x64 - network adapter for EtherCAT master not working ^{CODESYS Forge talk (Post)}
Hi guys I am trying to run on my laptop Codesys 3.5.19 Control Win x64 where I created a EtherCAT master. I have defined the controler, specified network adapter (my docking station) and everything worked as expected. Later I needed to test it on site (without docking station) so I changed the network adapter by EC master to my laptop network card. After that it shows "Network adapter opened" but no device can be found by scanning and in LOG is saying "SysEthernet: packet could not be sent, error code: -1". Same error with USB network card, but if I switch back to docking station, all is working again... Any idea what I'm doing wrong?

Post by jmorit on CAM Table - Quadratic velocity ramp with jerk limitation ^{CODESYS Forge talk (Post)}
Hello, I'm working on setup a CAM table by using the Codesys CAM Editor. My purpouse is to obtain a quadratic velocity ramp with jerk limitation motion profile, for which i define the accel/decel phases with Poly5 segment type, but the problem is that due to the fact i can "only" adjust until the acceleration, and the jerk is always setup to 0, and i cannot change the jerk values, i cannot achieve the desired results, as i need to generate jerk steps. Is there any way it can be achieved with the editor, or maybe by using PLC runtime code? Thank you in advance for your help BR, Jordi Morito

Post by peterned on Programatically restart Codesys OPC UA server? ^{CODESYS Forge talk (Post)}
Hi, I'm using a Festo Codesys PLC (CPX-CEC-C1-V3), which is connected to a HMI panel. Both exchange data via OPC UA. Occasionally, the HMI stops displaying data, and looks as if there is no connection. If the HMI stops, the only way to make it work again is to restart the PLC. Restarting HMI has no effect. When the PLC is restarted, HMI starts working normally again. Is it possible to restart the OPC UA server from PLC code? I hope this will make fixing the HMI possible without a PLC restart. Thanks
