Hi, works in my case if I increase the timeout! to_udint(t#100ms) -> 100 -> 100us.. FUNCTION_BLOCK MODBUS_master_example_ST VAR initDone : BOOL := FALSE; aIPAddress : ARRAY [0..3] OF BYTE := [127,0,0,1]; clientTcp: ModbusFB.ClientTcp; // buffer to read input registers aDataInputRegisters : ARRAY[0..9] OF UINT; // some client requests clientRequestReadInputRegisters: ModbusFB.ClientRequestReadInputRegisters; xExecute: BOOL; uistart: UINT := 100; udiTimeout1: UDINT; END_VAR IF NOT initDone THEN initDone...
Hi, I'm using SP19 Patch 5, the software is also updated from SP18 Patch 5, I forgot to mention this. I will try a newer patch to see if it fixes the issue. Thanks for your help.
Okey, I will try this out. Thank you for your answer!
I'm using the code bellow which is based on the Codesys example: FUNCTION_BLOCK MODBUS_master_example_ST VAR initDone : BOOL := FALSE; aIPAddress : ARRAY [0..3] OF BYTE := [127,0,0,1]; clientTcp: ModbusFB.ClientTcp; // buffer to read input registers aDataInputRegisters : ARRAY[0..9] OF UINT; // some client requests clientRequestReadInputRegisters: ModbusFB.ClientRequestReadInputRegisters; xExecute: BOOL; END_VAR IF NOT initDone THEN initDone := TRUE; // configure clientTcp clientTcp(aIPaddr:=aIPAddress,...
Is there a way to run Codesys HMI on two different PC's and have the web visu clients fail over to the HMI instance that is wokring or running?
Disable the setting "Support client animations and overlay of native elements" in the Visu Manager. Activating this setting should also set a compiler define (GENERATE_OVERLAY_VISU). Maybe the compiler define is set and the feature is not activated in the visu manager or or the other way round.. rightclick the Application -> Properties -> Build https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_dlg_properties_build.html

Hi, it is enough to copy the files to /home/codesys/PlcLogic/Application and adding the lines [CmpApp] Application.1=Application to the eRUNTIME.cfg, if your Application in your program is also called "Application". Reboot -> Bootapp should be loaded. If not please check the log /var/log/runtime.log There should be a line which explains why the bootproject is not loaded.
Hi, which CODESYS IDE version are you using? I think it's fixed in >= SP19 patch 7, maybe also in SP19 patch 6, but I'm not sure.
I think you can use the newer versions. For a explanation from CODESYS, please read this post: https://www.codesys.com/the-system/versions-modularization.html
