IF you have an USB interface type in "Peak_USB" for CAN card driver (Name of CAN card driver). No need to add libraries for communication via CoDeSys Gateway. For other card types contact PEAK support and they will help you. Regards,

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?

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?

Best way.. in CNC program before G20 jump, set G75. And for fbCheckVel execute if fbInterpreter.bWorking AND fbInterpreter.bLastObjectWasAdministrative; and same for Interpolator. " ..... dumm := fbInterpreter.bWorking AND fbInterpreter.bLastObjectWasAdministrative; //Check velociteses. fbCheckVel(bExecute := (fbInterpreter.bDone or) dumm, bAbort := gCNC.bCycleStop, poqDataIn := fbInterpreter.poqDataOut); "

Old question but since I stumbled on it others might. He probably added the function he wants to be called before using the "add event handler". If you don't add it first they will be created with the correct params.

looks like your _hHash handle is "empty" (00000) at the breakpoint! I don't know if CryptoGetAlgorithmById(...) call in the VAR section is possible? would be good to know.

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.

it could be due to security settings. In codesys IDE, go to device-> change run-time security policy, and click the checkbox that says "Allow anonymous login". try if this works.

Also. Every third (or so) attempt to login/compile is unsuccessful with the error prompt "one or more errors occurred", however there is no information available on what this error might be. If I remove the PersistenceManager-module, these problems are not present.
