hello guys,
I am looking for a solution for something similar. I have an OPC UA server connected to an ignition. I have a sensor that shares status values, so I have set an alarm for that status. When an alarm is generated, I have to acknowledge it and send back an acknowledgment to the server. So I have tried first with Prosys opc ua browser to call back for acknowledgment, and there it works perfectly. I have added images for ref, so now I want the same thing: when the alarm generates, I want to send an ACK back to the server from the ignition. and every time an alarm is generated, the event ID value for that alarm is unique, so if I want to send ack back to the server, I have to use that same value for ack. In the image, you can see that. in the prosys browser, value data type is a different hexadecimal byte string, for example: [16]0xb8e743902ec9754cb5ab6d3efb8f86e3. and in ignition value coming in string like:[74, 114, 204, 88, 25, 136, 159, 209, 254, 107, 153, 13, 172, 149, 135, 38]...so please guide me how can acknowledge the alarm from ignition to the server back
