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 := TRUE; // configure clientTcp clientTcp(aIPaddr:=aIPAddress, uiPort:=502, udiLogOptions := ModbusFB.LoggingOptions.All); // configure clientRequestReadInputRegisters clientRequestReadInputRegisters(rClient:=clientTcp, uiUnitId:=1, udiTimeout:=1000000); // 1sec END_IF // call the client FB's clientTcp(); clientRequestReadInputRegisters(rClient:=clientTcp,xExecute := xExecute AND NOT clientRequestReadInputRegisters.xBusy ,uiStartItem:=uistart, uiQuantity:=3, pData:=ADR(aDataInputRegisters[0]));

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, uiPort:=502, udiLogOptions := ModbusFB.LoggingOptions.All); // configure clientRequestReadInputRegisters clientRequestReadInputRegisters(rClient:=clientTcp, uiUnitId:=1, udiTimeout:=TO_UDINT(T#1000MS)); END_IF // call the client FB's clientTcp(); clientRequestReadInputRegisters(rClient:=clientTcp,xExecute := xExecute AND NOT clientRequestReadInputRegisters.xBusy ,uiStartItem:=2, uiQuantity:=3, pData:=ADR(aDataInputRegisters[0])); As you can see the clientTCP is called cyclically with the same result.

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.

Hi, I would like to automate opening some specific pous and visualisations in the codesys environment I found out that I can open it by using : system.commands["42f6acb9-bd6e-42e7-94bb-6e2a03973b83"].execute() But the POU has to be selected in the Devices or POUs navigator. Does anyone know how I can select a specific POU in the navigator? Or how I can open a specific POU? I can retreive the guid of the POU. Thx

Hi, Thank you for your suggestion but the problem is fixed after I disabled and enabled the network adapter from Windows settings.

Post by starmaxou on How to download dependencies packages for CODESYS Control for Raspberry Pi SL ?
CODESYS Forge
talk
(Post)
Hi everyone, I'm trying to install the CODESYS Control for Raspberry Pi SL package. The computer with CODESYS software is offline for security reasons. So, I downloaded the package on another computer and installed it manually. But this package has dependencies packages: CODESYS.Control SL Extension Package, V4.0.0.0 CODESYS.Control SL Deploy Tool, V4.10.0.0 As I said, the computer with CODESYS is offline. I cannot use the package installer to search for these packages. I did not find them in Codesys Store with another computer. Do you know where to find and download them? Thank you in advance for your help!

Hello Ullrich, .package should have been obvious enough but I guess I missed that part somehow so I had not tried to unzip that compressed folder. Not a whole lot familiar with libraries as well so. Thank you very much for your time as I effectively found the required project file that way. Kind regards, Mike

Hello all, Recently started using Codesys V3.5 SP20 as I need to improve my programming skills. My actual problem is that I am trying to locate the following project: Building Automation Examples.project It says on Codesys website (https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_bacn_building_automation_examples.html): The project is located in the Projects installation subdirectory after installing the CODESYS Building Automation library package. I searched within all Projects folder, that have to do with Codesys, I could locate but no can do!!! Even performed search with the Codesys folders but it would not come out. I also checked on forge.codesys.com...is it me ?? Initially I ran the following packages listed below: CODESYS Building Automation 1.0.0.0.package CODESYS in Building Automation Examples.package ** NOTE: Both packages installed correctly I then opened up Codesys V3.5 SP20, started a new blank project, went to library manager and added library Building Automation 1.0.0.0. Properly added as I can see the library’s components. So I believe I am ready to load the Building Automation Examples.project listed above; correct me if I am wrong. Any help would greatly be appreciated guys Mike 2024-05-30 17:27:59.240000 Ticket #2: Cannot locate Building Automation Examples.project CODESYS Examples codesys-example tickets tickets False /prj/codesys-example/tickets/2/ Ticket Building Automation Examples Cannot locate Building Automation Examples.project False 1 2024-05-29 22:00:34.876000 2 Cannot locate Building Automation Examples.project open Hello all, Recently started using Codesys V3.5 SP20 as I need to improve my programming skills.
