Gateway and runtime (Control for linux SL) on a debian linux. Thanks for your check. Good to know. I will probably travel there in about a months time so that will give me better possibility for further testing. (on a side note, I dont get mail-updates on forum-subscriptions, need to check the topics manually)

*** The system may be in an inconsistent state, please reboot *** *Exception* Async service: ServiceGroup=17, IP=0x5fa45617, Component=CmpSrv Every time at the instant that I Login to the system a message that the "system may be in an inconsistent state, please reboot" is written in the log. If I logout and repeat login a new entry is set. My system is a "Control for linux SL" running on a debian linux host. Im running it on my desk without any IO attached so message might be caused from that, but...

An update note. Still using linux/Qemu. Still happy, but sometimes some things are harder. I lost the "bridge" connection to my VM (meaning for instance I couldnt "scan network" and find local units. Have spent tons of hours to find out why. Finally it seems the traffic got blocked by the firewall/iptables so needed to set rules for that. So friendly note that rules must allow forward traffic to/from you configured host bridge device.

I have a Hmi that acts as an interface for many (mostly identical) units. This is managed by a sort of "mux" where you select which unit that should be presented on the HMI. Backbone is solved by a HMI-gvl defined as reference/pointer to "unit-data", which then can be set to the individual units. While this works for most data I still have not sorted how to solve this for the trend recordings. One solution would be to have already "mux:ed" data values as source for the/one trend. However then the...

You should use PLCnext if your device-hw is a PLCnext-un it. As I understand it you are using "CODESYS Control Win V3 x64".

The structure should be the same independent of which runtime version. Im using Codesys control for linux SL. Ie, add an ethernet device, then profinet controler then phoenix PN bus coupler.

Pretty much my configuration, see attached.

After enabling user management, then reverting to "legacy mode" for visu, the web is responding again also for versions later than 4.14.0.0.
-
Ok, seems user management is enforce from versions later than SP14, is that what I see with 4.14.0.0 -> 4.15.0.0 and later (?)

I have a problem which I have identified with a device-update from 4.14.0.0 to (4.15.0.0-4.17.0.0) where the newer versions will stop any local access to the internal web page with the browser responding "The requested URL requires authentication". Setting the device back to 4.14.0.0. the web page will respond. Access to web page through Automation server is possible also for the newer version, but not "local" access. Runtime (Codesys control for linux SL) is on 4.17.0.0. I have tried to manipulate...

Trying to communicate (from Europe) with/to a unit located in china, the communication seems blocked/stopped. The edge gateway is installed in a linux environment and was possible to link to my Automation server account using the "Automation service tool". However it seems the unit cannot communicate with the Automation server (a Network scan will give the message "Gateway not connected"). (I have tested the eq. setup with units locally which works.) Anyone having experience situation similar to...

For the protocol. What also works is to do the process via ssh (using runtime on linux) sudo /etc/init.d/codesyscontrol stop modify the persistence file values sudo /etc/init.d/codesyscontrol start

I swear I tested this like 20 times yesterday without success. Repeated it today and it works. Maybe the system needed a "real" power reboot? To note. To make a manual edit of a variable I tried some different approaches this is what worked for me. "system/online edited" gvl_var.example_variable REAL:F16#2FFB334H-4 767.7 "manually edited" (with runtime stopped followed by a "cold start" to read from file) gvl_var.example_variable REAL:790.1 (the system will use the manual value but will not set an...

Im struggling with the AC Persistence. AC persistence seems to work for any variable that is changed online and values are kept during reboot. However, if I try to edit the persistence files offline or replace the persistence files with a previously downloaded older persistence file (with modified values), the online value will not follow, as if the system did not at all read the file at boot? My testing sequence. - Edit a the value of a persistenced variable (with xSaveOnChange = True) - Save/download...

Confirmed. Variable types that should be excluded: BIT Pointer Interfaces Constants Arrays of non-persistent data types Docs: https://content.helpme-codesys.com/en/CODESYS%20Application%20Composer/ac_pm_definition_persistent_variables.html
-
Ok, think I understand. The reason for the error is I try to include complex variables (FB) in the persistenced data. I will try to use {attribute 'ac_persist_exclude'} to exclude those elements.
-
I still cannot enable persistent manager for my project (and successfully login to a device). Project compiles with no errors but during download/login it fails with the fairly limited message "one or more errors occurred". The only clue I get from the system that this messages is displayed during "Generating code..: relocation pou". Any tips pointing me in a direction how to solve this very much appreciated!

I have done the switch (linux mint, virtual windows through QEMU/KVM) now and is generally pleased. Have had problems in two areas initially. To bridge IP to the Virtual unit (solved), I overthought things initially. Solution. Configure manually a bridge in the mint-"network connections". Use that bridge in the Qemu settings as "Bridge device", "Device name": "name of the configured bridge" Figure out where to store the projects. I started out have the data in linux world (sort of) and linking it...

Using Codesys runtime for Linux and thinking of the process of preparing multiple such systems for my customer. I don't necessarily have physical access to these units, they can be (very) remote. The idea so far is to use an image to install the Linux OS and codesys runtime. Application updates can be done by distribution of the PlcLogic/Application/application.app and application.crc files. But whats the most practical way of managing the license for these units? Do each controller need to be physically...

Back in november I paused this, but wanted to reattempt using the persistent manager, the behavior is still the same. Most "login attempts" s are stopped with the message "One or more errors occurred" but I have no idea what that error might be. The only clue is this message is presented while the lower left status box says "Generating code...: relocation pou". For clarification. Build/Generate code is successful, no errors. Error appears when I try to download/login (physical or simulation) to a...

Interesting, thanks! Didnt know about ANY before, and will sure find a use-case for it. Im not sure it will help me here though, it seems to me that an ANY will not accept a string assignment? I actually think that the "ALIAS" should work, that was a hard found error. I had a fair bit of scratching my head looking for misdirected pointers before I understood what was (not) happening. I will use the work-around of individual structs instead.

Apparently my construction will not work as any of the sub-types are not be able to accept any (further) value-initiation. Ie: string_item : log_data_base := (string_value := 'test', val_type := STRING_); is not eq to (the string_value will not be assigned): string_item_2 : log_data_string := (string_value := 'test'); Because effectively for the compiler this is eq. to a "double" assignment where the compiler sees only the first assignment (my guess). string_item_2 : log_data_base := (val_type :=...

Started playing with the idea of ditching windows for linux, one of the obstacles would be Codesys development. Alternatives: - linux with wine? - Run windows/codesys through virtual machine I guess a vm is the way to go? Anyone out there that could share their experience?

Easier that I thought, by ALIAS TYPE log_item_val_type : ( BOOL_ := 0, INT_, REAL_, STRING_ ); END_TYPE TYPE LOG_DATA_BASE STRUCT val_type : log_item_val_type; (* value, name etc *) ENDSTRUCT ENDTYPE TYPE LOG_DATA_BOOL : LOG_DATA_BASE := (val_type := log_item_val_type.BOOL_); END_TYPE TYPE LOG_DATA_INT : LOG_DATA_BASE := (val_type := log_item_val_type.INT_); END_TYPE TYPE LOG_DATA_REAL : LOG_DATA_BASE := (val_type := log_item_val_type.REAL_); END_TYPE TYPE LOG_DATA_STRING : LOG_DATA_BASE := (val_type...

Im looking for a way to define predefined version of the same structures through "extends"/inheritance. What I want to do is best shown with an example: TYPE log_item_val_type : ( BOOL_ := 0, INT_, REAL_, STRING_ ); END_TYPE TYPE LOG_DATA_BASE STRUCT val_type : log_item_val_type; (* value, name etc *) ENDSTRUCT ENDTYPE (* this/below is not possible as I understand from the compiler?? *) TYPE LOG_DATA_BOOL extends LOG_DATA_BASE : STRUCT val_type : log_item_val_type := log_item_val_type.BOOL_; END_STRUCT...

I think this will not work. I reworked and used an int as source instead.

I have a time which I want to modify with a slider. I have confirmed it is possible to set the value of the slider by to_real(time) (I can see that the slider changes according to 'my_time_value's value). Slider variable: to_real(my_time_value); However I fail to access the current slider instance value when I want to write back the value as time (write to a variable will not work as I need a type-conversion before assignment). my_time_value := to_time(slider-instance-value); I tried with this^.?...

I have a debian linux host running Control SL. I tried to manage IP-addresses through codesys/Control SL but that was not successful. What works though is manually editing the network-interfaces config file. /etc/network/interfaces. Is there a way to set this up so that IP-addresses can be managed from within codesys instead? Thanks! / Per

Never seen VAR_TEMP before, but seems to be what I was looking for! Thank you!!

Thats what I did. The files existed originally, but when I had problems logging in as described I deleted those files (if they in some way had been corrupted causing my problems to login?). After that I have not managed to get the system to re-created these def-files. I manually created the folder structure (from CODESYS file browser) but this has not helped.

Also. Every third (or so) attempt to login/compile is unsuccessful with the error prompt "one or more errors occurred", however there is no information available on what this error might be. If I remove the PersistenceManager-module, these problems are not present.

Trying to utilize the persistence manager, but system do not write to file and do not create the config file. System is a Linux SL, version 4.13.0.0 Problems with persistence/config started when I had other problems to go online, I deleted the config file and the persistent files, but the system will not re-create them. I have tried to remove/re-install the "PersistenceManager"-module, create the folder-structure myself. And also reinstall the linux-runtime but its clearly not working. Any help ...

Im using a pointer as input for a FB and for convenience I like to use 'referenced' variable internally. I use this setup in methods which works because internal variables are instantiated for each call. In a FB these variables are instantiated and initiated for the first call only. Is there a pragma/attribute available that changes this behaviour to mirror a 'method'-call?

I have a project where a single PLC shall control multiple nodes (up to 10 units?) with IO connected through profinet. Ideally each node should be identical however with time I see situations were different setups/configurations will be used.
