Configuring the OPC-UA server

TK

OnTakt configuration

Set the following options in the machine setup area:

System: OPC-UA
Model: SINUMERIK 840D sl
NC URL: opc.tcp://IP:PORT, where IP is the IP address of the control and PORT is the configured OPC-UA server port. The port defaults to 4840 if omitted. No path is necessary after the port number.
NC authentication: username:password, where username and password are the OPC-UA username and password configured in the OPC-UA settings on the control. If this has not been changed, it's probably OpcUaClient:OpcUaClient.

Part counting

Variable part counting

Instead of using the built-in part counters, OnTakt can also read an R-variable and interpret it as a part counter. This way, the part program can increment the part counter by incrementing an R-variable. For example, the statement R5=R5+1 increments R-variable number 5.
