Further information about the configuration of the CNC may be available from the machine manufacturer or the Siemens documentation available online. If this is available or the CNC can be upgraded and licensed to the proper CNC software version (v4.5 and newer), use the OPC UA Client driver to integrate CNC data.
Newer Sinumerik systems have an embedded OPC UA server interface available to access data. In this case, use the OPC DA Client driver to connect to the OPC DA server interface on the NC. The embedded PC (NC) typically has an OPC DA server interface available that can access NC and PLC data from the Sinumerik CNC. In this case, use the Siemens Suite of drivers to access to S7 data types available on the PLC. The Siemens Sinumerik controllers (such as the 810D and 840D) consist of a PLC and an embedded PC, sometimes called the "NC." KEPServerEX can connect using three methods, depending on the CNC configuration: KEPServerEX can connect to the Sinumerik PLC like any S7-300 PLC if a port (like Ethernet) is available on the PLC in the CNC installation. I do not work with TIA (Portal) I think.Can KEPServerEX ® Communicate with a Siemens Sinumerik CNC? Yes.
Kepware is now entering the OPC server toolkit market with CID - a Custom Interface Driver add-on to KEPServerEX. The OPC UA server is KEPServerEX and the OPC UA client is in WinCC, and the problem only occurs when authorization is enabled. new Kepware is a latecomer to the OPC toolkit arena, but its KEPServerEX product has been a leading multi-protocol OPC DA server for a number of years. The PLC should not be the problem I think, because it has nothing to do with the OPC UA connection. The PLC is connected to the OPC UA server by ethernet, and PUT/GET enabled (I can browse tags and have a secure encryption/sign connection without authorization). Or is your OPC UA Server able to connect to S71500 through S7 Protocol?ĭo you use optimized Data Blocks? if yes try with absolute adresses.ĭo you have activated Put/Get Communication in S71500 at Security Settings? It has to be activated that your OPC Access could work.ĭo you work with TIA Portal V14 if yes there is a new column in the Data Block editor in which you could activate the OPC /HMI Access. First of all the question how do you get access to the S71500? Do you use the new OPC UA Server functionality of the Firmware V2.0? with TIA V14
