Post by gabrielarffa on Modbus TCP/IP having problems with global variables ^{CODESYS Forge talk (Post)}
I'm using Modbus TCP/IP to communicate Codesys with Elipse E3 as the master for a college project. I have made a list of global variables to organize the programming in two different POUs. The problem is, when I try to do the mapping of variables, the program informs me of an error due to the identifiers having a "." on their names. Do I have to reorganize my code to make it an unified block or is there a way to declare their names without changing all the code structure?

Good morning, I'm using a raspberry pi3 as plc with the runtime 4.9.0.0. My program has many of retrain variables but when an update is performed the retrain variables comes back to default values. Is the a way to backups the retrain variables n a csv file? Is still the way to restore them from the csv? Thank you for helping Luca

Post by gatto on variables between two applications ^{CODESYS Forge talk (Post)}
Hello, I'm experimenting with two applications. I was able to start stop applications with the CmpApp library. Currently in my test the variables declared in the first application are not visible and writable in the second. I ask if there is the possibility of having variables that are visible both in the first application and in the second.

Hello , will this be changed in an upcooming version? The current method is to use all the color Variables for buttons and object as changeable variables but the amount of work for this results in a bad cost-benefi ratio.

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.
