I'm now circumventing the problem by creating a separate TCP client for all Write actions. Upon registering a changed variable, I enable this client, until the change is processed.

I've managed to run Ladder logic code on a virtual PLC running on my laptop. Now, I want to connect to a device over EthernetIP, but I always get the "No driver found" message. Can anyone shed me some light?

Post by climblinne on Calling OPC UA Methods from UaExpert ^{CODESYS Forge talk (Post)}
So I found the mistakes. First I forget to deactivate "Use access rights defined in the user management". And also I used in "UaModeler" a project name with whitespaces, which lead to a wrong namespace name.

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?

You can use the R_TRIG and F_TRIG function blocks to generate a pulse in Rising or Falling edge of your signal. Have a look here: https://content.helpme-codesys.com/en/libs/Standard/Current/Trigger/R_TRIG.html

Post by drml on Array to String ^{CODESYS Forge talk (Post)}
If a size is not specified, CODESYS allocates 80 characters by default for a string. After 7 seconds, does your Json_string contain all of your 20000 key/values? Or is the result truncated to 80 characters?

Hello, Is there a maximum number of Masters that can connect to a Modbus Slave that is configured in the device tree? Is this limited by the CODESYS IDE, or the manufactures hardware and CPU load? Thank you,

With this kind of motor nominal tourque I can belive that it can be moved very easy. 1,6 Nm is, for example, the torque required for unscrew a small loose cap from a bottle.

First of all you need to enable "Use unicodestrings" in the Visualization Manager. This function returns a pointer to a WSTRING (not STRING). To get this wstring value, do something like this: VAR myWstringVariable : WSTRING(255); END_VAR myWstringVariable := myResult^; // this is dereferencing the pointer to the WSTRING.

It would be such a simple fix to first check if the file is missing or changed before writing to it, onedrive only has a problem because codesys writes to the file every second no matter the change.
