Thanks Georg, that fixed it.

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.

Vijeo doesn't support TIME variables, so the easiest thing to do is convert to a STRING in your program, and use that variable. You could use TimeAsString:= TIME_TO_STRING(TimeVar) to get a string that looks like this: T#5h10m45s200ms

Hi. I'm trying to show in Vijeo Designer a timer countdown. But I want to display the data in hour, minutes and seconds. I tried to change the data by converting in the Machine Expert but not able to succeed. Can you help me to find a solution? Regards, FG

Since version 19 they changed how file access is handle. There are two solutions: 1. You change where the file is stored (need to go to: /PlcLogic/) 2. You can, if you don´t want to store at PlcLogic, add the following line in the CODESYSControl.cfg under [SysFile]: ForceIecFilePath=0 The CodesysControl.cfg is at C:\ProgramData\CODESYS\CODESYSControlWinV3x64\xxPROJECT_NUMBERxx\ Here the email they sent me: "with the 3.5.19 Version we changed how files are handled.

You can try this setup: DINTVar := SHL(INT_TO_DINT (Low_Word_INT_Var),16) + INT_TO_DINT(High_Word_INT_Var);

Why will it retain the sum value from the last call? This is how PLC work. Usually variables only get initialized after a download or a reset (i.e. power loss). RETAIN variables are saved in a special kind of RAM and keep their value after a power loss. To initialize variables on every call of your FB use the VAR TEMP block. VAR_TEMP sum : INT; END_VAR

I need to connect 2 computers on the same network that are running codesys, so that they can receive and change variable values from each other. This connection must preferably be made using Modbus.
