Hi PLC4X team, I searched online and find your answers to my question. I checked no leading and trialing spaces and used both, ns=2;s="S7PLC".CureAbort:BOOL and ns=2;s="S7PLC"."CureAbort":BOOL formats, I got NOT_FOUND instead of ACCESS_DENIED.
It seems my original one is right(my C# app wrote correctly with this), but writing is denied by some unknown reason (in my java app). Is there other check list that I can follow? Thanks, Jim From: Wang, Jim Sent: Thursday, March 11, 2021 09:21 To: [email protected] Subject: OPCUA Write Hi PLC4X team, When I use PLC4X's OPCUA protocol to write PLC, I always get ACCESS_DENIED for the PLC's tag (Reading is OK.) I list my code and message I get below in FYI: sections. How can I get rid of this issue? Thanks, Jim FYI: my codes ================================== public static void WritePLC(PlcConnection plcConnection) throws InterruptedException, Exception, TimeoutException { PlcWriteRequest.Builder builder = plcConnection.writeRequestBuilder(); builder.addItem("S7PLC.CureAbort", "ns=2;s= S7PLC.CureAbort:BOOL", true); PlcWriteRequest writeRequest = builder.build(); PlcWriteResponse response = writeRequest.execute().get(); for (String fieldName : response.getFieldNames()) { if(response.getResponseCode(fieldName) == PlcResponseCode.OK) { System.out.println("Value[" + fieldName + "]: updated"); } else { System.out.println("Error[" + fieldName + "]: " + response.getResponseCode(fieldName).name()); } } } FYI: the message when I run my codees ====================================== opcua:tcp://localhost:49601/ [main] INFO org.apache.plc4x.java.PlcDriverManager - Instantiating new PLC Driver Manager with class loader jdk.internal.loader.ClassLoaders$AppClassLoader@443b7951<mailto:jdk.internal.loader.ClassLoaders$AppClassLoader@443b7951> [main] INFO org.apache.plc4x.java.PlcDriverManager - Registering available drivers...
