Hello,

I’m writing a small module in java to be put in ignition. I’m trying  
to expose tag to OPC-UA client as described on your website. I’m able  
to expose tag and to override the write handler as decribed on the  
user manual :

ourProvider = new SimpleTagProvider(“DynamicTags”);

ourTagType = TagType.Custom;  
ourProvider.configureTagType(ourTagType,  
TagEditingFlags.STANDARD\_STATUS, null);

ourProvider.configureTag(tag.getKey(), tag.getDataType(),  
TagType.Custom);

ourProvider.registerWriteHandler(tag.getKey(), new WriteHandler() {  
@Override  
public Quality write(TagPath target, Object value) {

…

But each tag I create has a read/right access when I connect a OPC-UA  
client to the gateway. Is there a java way to configure tag in read  
only mode?

Best,
