I did check I cannot see any error log. It is when executing the Reconfigure function that I get an error as return from that function.

Post by alex-wall on Network Variables not updating ^{CODESYS Forge talk (Post)}
This worked for me. I had four identical PLC's. Three of them worked just fine with 255.255.255.255 as the broadcasting address but the 4th would not update the variables. Changed it to 192.168.x.255 and everything worked.

Go to Online>Communication Parameters...>Gateway>TCP/IP> Click on "New..." and reestablish your connections with whatever IP address and set up information you have. Bypass whatever is necessary as you may have to redownload to the PLC.

I have done: systemctl stop dhcpcd sudo ip addr flush dev eth0 sudo ip link set eth0 up but a call to SysSockSetIpAddressAndNetMask does not give the eth0 an IP address Why?

Post by snhatton on Retain memory change to ZERO ^{CODESYS Forge talk (Post)}
I think more information is needed to help solve the issue. Can you list the exact steps to reproduce the issue? What version of Codesys are you using? Did you add a persistentVars object to your project? I would recommend browsing all instances of the retain variable to see all possible writes to the variable in question.

Post by simotion on Variable indicating axis pending gearing or camming ^{CODESYS Forge talk (Post)}
Is there a variable indicating that a gearing or camming operation is pending? For instance MC_Gearin has beeen triggered, but starting point of master axis to start the sychronisation movement is not reached yet, so the slave axis is just waiting for this. I should be able to differ between a pending and active gearing or camming

Hello I have a problem with the Frame-configuration. In the picture below you can see that I set the Editor Type to variable. If it would be text it would work, but it wasnt variable anymore. Thanks for your time. Sorry, my codesys is in German.

Hi, i am interested in this thread and have tried a couple of the above examples in to determine remote webvisu access. I am having trouble getting the lastusage variable to refresh during runtime? It seems to only log the last usage at initialisation and that is it? how do i gain ongoing access to the time variable as the code is running? Thankyou.

Post by timvh on Colors look different when logged in and running ^{CODESYS Forge talk (Post)}
At the top of the Visualisation Properties View, you can enable the "Advanced" options. This will give you access to more properties than what you currently see. There might be a variable linked to the "advanced" colour property where the fill colour is determined by the value of this variable (dword).

Hi. Raspberry pi 4 runtime. Runtime version 4.16, IDE version 3.5.21. Is it possible write new value for variable via modbus tcp or serial devices when both enabled? As I see - not. What can I do? It is terrible restriction.

Hello everyone, I was just wondering if anybody knows if there's a way to pull the string name of the current visualization without using the current visu variable. I'm working on a project where we don't want web clients to change the current visualization on the HMI of the machine. Thanks!!

Post by stuartjr on Disabling forcing of specific variables ^{CODESYS Forge talk (Post)}
So I think I've found a way to do what I want, but its a not as simple as I thought it would be. Essentially I've got to put my "logic" that decides what the GVL variable should be at the start of every task (rung 1). Then regardless of what the force is the variable will be set to what the logic decides.

Post by stuartjr on Disabling forcing of specific variables ^{CODESYS Forge talk (Post)}
I also thought that if I had logic writing a value to this variable, then it would override the force anyway, since I thought that the force request was only applied at the beginning and end of the PLC scan. But this doesn't seem to be the case, the force persists throughout the logic regardless of what I write to the variable with logic

Post by arundara on Variable Sync Issue In Soft Plc Redundancy ^{CODESYS Forge talk (Post)}
Hello, I was trying to create a redundancy POC for our application where we read data from few modbus tcp devices. As there is a limitaion that modbus tcp device support only for single master device, we wanted to test how the variable sync happens in redundancy mode. For that i have used the redundancy sample code added a variable "b" under a condition. What i observed was while active controller is running, if passive controller is powerup, passive controller is able to sync all the data configured for redundacny. But after that the variable data which resided under a condition is not synching from active to passive controller. I have attached the image where i have highlighter the variable. Can some help me to understand how redundacny work in codesys soft plc and if there is a solution to sync variable which are under condition, please explain the same or suggestion to achieve the same. Hardware - Raspberry Pi (2 qty) Redundancy licence used - yes in both controllers. Codesys runtime - 4.9.0.0 Codesys software version - V3.5 SP19 if i have posted this question in wrong section, please do let me know in whcih section i have to post this question.
