Post by askic on PLC error log help ^{CODESYS Forge talk (Post)}
Hello, I'm using Codesys 3.5.20.0 version and I noticed that even with the most basic standard project create, there are error messages like shown in the acttached picture. The similar questions are already asked here on the CODESYS Forge Talk, but remained unanswered. Exact screenshot is attached, but essentially I would like to know which component in the Codesys has CmpID = 0x00000019 and what this Timeout means?

Hello, I have two warning on my code, and I would like to understand why. C0540: Attribut 'no_assign' missing for the 'FB_MOdbusReadHolding'. The type of the variable clientTcp is set to 'no_assign'. In this FB, I have done: clientTcp : ModbusFB.ClientTCP; clientRequest : ModbusFB.ClientRequestReadHoldingRegisters; The error comes from clientTcp : ModbusFB.ClientTCP; I am using ModbusFB 4.4.0.0. Thx a lot

Thx for your help, I just Uninstall and install again codesys. I did it as admnistrator and now it is working... I did not change anything into the target configuration. Only my codesys on my computer. Loic,

Post by mubeta on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
Hi gseidel, before moving to HW implementation, I had created the same program in simulation mode with virtual drives and, as far as I remember, everything worked fine simulating process and the few useful inputs. So it does not seem to be a SoftMotion library problem, but rather a problem with dynamics or physical axis adjustments. What escapes me, however, is the fact that this function is supposed to perform a position shift virtually, in fact without interfering with the axis itself, thus independent of its adjustments. MC_SetPosition() is not a homing function, in fact it is clearly intended to be executed on the fly with the axis moving. Now I'll see if I can reduce the program, although I don't like it very much. In my life I have learned that problem searches should be done on the part, and not in a more or less similar way.

No errors in any condition. The function terminate correctly with the 'done' bit. Now I leave the machine and I don't know when I will be there again. The assumption you made I had considered. The operational limits of the axis are all fit for purpose, and this function should operate virtually without even noticing the motion limits. In fact in practice with the axis at low speed the function corrects any numerical value of the position in the range 0 ... 360° without any problem whatsoever in a single PLC scan cycle.

Post by teichhei on The selected container ... does not fit your ticket ^{CODESYS Forge talk (Post)}
After correspondence with Mr Schwellinger from Codesys the resolution for this was to uninstall the SL 4.14 and install SL 4.13 on the device. Once this was done the licensing worked as expected. I noted that the container then showed a Version 3.00 and not 0.00.

Post by andrax on Bosch BME 280 bzw 688 Sensor per I2C Bus steuern und Daten in Codesys verarbeiten ^{CODESYS Forge talk (Post)}
Die Geräte Bibliothek von Stefan Dreyer ist dafür gedacht, um Treiber für deine Sensoren zu erstellen, damit sie an einem MUX-Board betrieben werden können. Auch ist ein Betrieb ohne MUX-Board möglich. Der Aufbau ist relativ einfach und besteht aus folgenden Komponenten: -Initialize (hier wird die .devdesc.xml eingelesen) -BeforeWriteOutputs (ruft initDevice auf und ist für ausgehende Signale gedacht) -initDevice (initialisiert den Sensor) -AfterReadInputs (Selbsterklärend, Werte einlesen und Signalkonversation) Bei meinen Sensoren habe ich es immer so gemacht. Zuerst habe ich mit die .devdesc.xml gebaut bzw. eine Vorlage umgeschrieben, wobei Parameter 1-10 für ein Mux-Board reserviert sind. In der .devdesc.xml definierst du alle wichtigen Parameter für den Sensor. Danach schreibst du die Initialize und liest die Werte ein. InitDevice ist Fleißarbeit. Für die meisten Sensoren liegt immer ein Pythonscript oder was in C bei. Du gehst die Scripte durch und baust es in Codesys nach. Im letzten Schritt baust du die AfterReadInputs. Signale einlesen und Conversation. Du solltest dir auch ein I2C-Logic Analyzer zulegen. Da Teil ist sehr hilfreich um die I2C Kommunikation mitzulesen. Wenn es irgendwo klemmt, siehst du sofort an welcher Stelle du suchen musst. Ich hab hier den AZ-Delivery Logic Analyzer! Grüße Andre

Hallo, Wenn ich meine Projekte im Simulations - Modus laufen lasse bekomme ich für alle devices die Meldung "No driver found". Auf meinem Raspberry Pi laufen sie aber. Ich kann nicht genau sagen seit wann dies auftritt, bin mir aber recht sicher, dass es mal funktioniert hat. Ich habe Codesys 3.5 SP20 Patch 4. Ich würde mich freuen, wenn jemand helfen könnte. Danke und viele Grüße.

Post by climblinne on OPC UA Method - How to wait for result? ^{CODESYS Forge talk (Post)}
Hello, I am already able to run an OPC UA method in Codesys. Now my question, how can I interact with other tasks (e.g. read an SDO from EtherCAT and return it by the function)? The OPC UA method seems to be called only once (I tried to return BOOL or UINT values). Up to now I only found to do a while loop to wait for the result of the other task. Is there a better way to do it? Is this the way OPC UA functions should be used (for "not too long" function calls) or should I use another mechanism (method: Start, event: Finish, method: getResult)? Regards

Post by ekristoffe on Modbus UDP ^{CODESYS Forge talk (Post)}
UDP has no packet ordering mechanism, and Modbus protocol has no order checking mechanism nor session establishment. I'm sorry but this is false, Modbus IP based have the Transaction Identifier. Transaction Identifier - It is used for transaction pairing, the MODBUS server copies in the response the transaction identifier of the request. Modbus UDP make more sense than Modbus TCP in a local environment.

Post by mattplc on OPC UA Codesys 3.5 Symbolkonfiguration VS Kommunikationsverwalter und Python/UA-Expert ^{CODESYS Forge talk (Post)}
Hallo, bisher war die Benutzung der Symbolkonfiguration für die OPC-UA Variablen recht easy einsetzbar. Im UAExpert Tool konnte man im Klarnamen den String sehen. var1 = client.get_node("ns=4;s=|var|WAGO 750-8212 PFC200 G2 2ETH RS.Application.PLC_PRG.fbTest.StateActual") Die Anbindung an die Python opcua Library hat so eigentlich gut funktioniert. Auch zum debuggen im UAExptert, konnte man den Value so sehen wie die Varibale heißt. In meinem Fall ein Enum. Was seit längerer Zeit nicht mehr funktionier ist das eingeben von Enums. Im UAExpert kommt die Fehlermeldung "BadTypeMismatch" früher war das nicht der Fall. Da die Symbolkonfiguration demnächst bei Codesys 3.5 rausfällt, wollte ich den Kommunikationsverwalter nutzen. Jetzt schaut der String mit der Node ID komplett anders aus. Bsp.: NS5|Opaque|0x01000000A6E12A718AF7333ABAFA2D7686EF27669CF33071C7D034759DE601779DF62178E9 Hier sieht man den Value gar nicht mehr im UA Expert. In Python finde ich auch keine Möglichkeit die OPC UA Variable einzulesen. Python: var1 = client.get_node("ns=5;s=|var|0x01000000A6E12A718AF7333ABAFA2D7686EF27669CF33071C7F016759BDC7114.PLC_PRG.fbTest.sVar_1") Weiß jemand wir das in Zukunft läuft? ich hab etwas das Gefühl, das die Übergeordneten Systeme die OPC UA Variablen nicht mehr so einfach einlesen können oder mache ich etwas falsch? Danke
