Hi, I want to write data from Codesys to Microsoft access and want to save it as mdb file. There is a way to store data in excel(CSV) file but instead of this, I want to save data in access (mdb) file. Does anyone have a solution? Thanks

My guess is that's a STRING, not an INT type. And it's 128 bytes, not bits

Post by bruceae on Ethernet/IP Scan ^{CODESYS Forge talk (Post)}
Hello, I have a robot configured as a Generic Ethernet Module under Ethernet/IP Scanner. I can not see the change of state of the outputs coming from the robot on the codesys side in real-time. (The robot has it's own internal program that would changes the values of remote outputs 0-3 off and on). Also when I send data down to the inputs of the robot it doesn't transfer over as expected. As an example I'll send to the robot's input bit 0 a value of 1. It doesn't see that value change. However, when I write that input bit 0 back to a value of 0, the robot changes state and shows a value of 1. And if I change the state of a different bit, the other bits update properly, except for the bit that I changed. Any advice would be greatly appreciated, and if anything else is needed let me know.

Post by mikek10 on Error IoDrvEthernetIP: Connection Failure. (16#1) How to solve ^{CODESYS Forge talk (Post)}
Your connection configuration should look something like the attachment. Consuming assembly O->T will be the hex of the assembly you want to reference for output data - I want 102 (DO Data Only) shown in the Wago web page 102 = 16#66. Producing assembly (T->O) is the assembly you require for input data - again shown in the Wago web page - I want 108 (DI Data Only) or 16#6C Then set the number of bytes as per the data in the Wago web page too (both 2 in my case)

Post by alez on CANopen safety , SRDO error behavior ^{CODESYS Forge talk (Post)}
I have a project in which there is a Safety device in CANopen, and the PLC interfaces with it as Master. I would like to understand if it is possible to set the behavior in case one of the SRDOs that I receive from the slave is no longer received. From what I have seen, if the SRDOs are not received, the CANopen safety status becomes "Not in progress" and the mapped variables freeze at the last value detected. I want to understand if it was possible to set the variables connected to the SRDOs to take a default value (e.g. zero) in the event of a CANOpen error during reception.

Post by denkihitsuji on Content update through Data URI on Web Brower on Visualization Toolbox ^{CODESYS Forge talk (Post)}
Objective: I want to dynamically update the content with strings and JPEG images received from a TCP/IP socket. For this purpose, I am exploring the possibility of utilizing the Web Browser feature of the Visualization toolbox. Example: In a standard web browser, entering data:text/plain;charset=utf-8;base64,SGVsbG8gc3RyYW5nZXI= in the URL window will display "Hello stranger" on the webpage. Issue: When attempting to use this method in the Web Browser of the Visualization toolbox, the content does not display as expected. Instead, it shows the error:'Navigation to the webpage was canceled.'. Request: I seek guidance on how to resolve this issue so that the Web Browser in the Visualization toolbox correctly interprets and displays the data URI content. Alternative Solution Welcomed: Or, if it is possible to directly use Codesys Structured Text (ST) variables within an HTML page, this approach would also meet my requirements. Thank you for your attention.

Post by programmierer on Implementing UDP Communication ^{CODESYS Forge talk (Post)}
Hello everyone, I hope you can help me with my problem. I am new to programming and am currently working with a WAGO controller in our lab, which controls a heat pump. My goal is to send the electrical power of the heat pump (Pel_WP) via a UDP connection to a specific IP address. I am using Codesys version 2.3 and following the guide I found here: https://forge.codesys.com/forum/de/396/genmed-Konfiguration%20der%20UDP%20Kommunikation%20Cosesys%20S7.pdf. I have adapted the guide to suit my needs. The data sending works since I can force the reception value Pel_WP and the data is sent accordingly. However, I am having trouble with the receiving part. The reception value is not being correctly received, and the diSocket variable shows -1. The connection between the heat pump and the WAGO controller seems to be set up correctly, as the heat pump is listed under the communication parameters with the correct IP address. I have also attached images to provide a better view of the setup. I would greatly appreciate any support or suggestions for a solution. Thank you in advance!

Post by i-campbell on Official MQTT-Client: MAX_RECEIVE_BUFFER_SIZE_EXCEEDED ^{CODESYS Forge talk (Post)}
I can't answer why it's not resetting, but from the description of g_udiMaxReceiveBufferSize, I would guess the sum of sizes of the mqtt packets received in one cycle exceeded this value. So the answer may be to increase that parameter. https://content.helpme-codesys.com/en/libs/MQTT%20Client%20SL/Current/MQTT-Client/Common/Params/MQTTParam.html https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_dlg_library_parameter.html

Have you received any feedback or found any solutions to the load problem. We are running into similar issues, even without codesys running the load avarage is above 1 meaning that it is to busy already without plc code running. Hope you might have some more insight.

Post by tyronnosaurus on ReceiveWatchdog FB not working on J1939 P2P PGNs ^{CODESYS Forge talk (Post)}
Hi guys. I've got a device that sends a status message over J1939 and a PLC running Codesys to receive it. This message uses a P2P PGN (as opposed to a broadcast PGN). Codesys can only read it if I mark the J1939_ECU as "Local" (see screenshot 1). The message is received correctly, that is not the problem. The problem is detecting if the message stops being received. Local ECUs have no Watchdog checkbox to detect if the message has been received in the last X seconds. In order to implement a watchdog, I've used a ReceiveWatchdog FB. The same code works well for any non-P2P message, but doesn't work for this particular P2P message I'm trying to monitor. Even if I physically disconnect the device, ReceiveWatchdog.xBusy stays True, and ReceiveWatchdog.xError never triggers due to a timeout error. Is there any caveat in the ReceiveWatchdog FB that makes it unable to monitor P2P PGNs in Local J1939_ECUs?
