Most likely your IP address is set to 172.... because you use a VPN connection to your device. Probably best to use the other Ethernet interface for your modbus communication.

to get the address just use ADR( ) variables defined in a VAR_IN_OUT block are references pointing to the passed variables. VAR_IN_OUT MyVar: bool; END_VAR VAR adrMyVar: __XWORD; END_VAR adrMyVar := ADR(MyVar);

Thanks for the comment. I'm using Weidmueller UC20-WL2000-AC's and changing the broadcast address to match the current subnet this worked for me as well!

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.

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

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).

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!!
