CNCnetPDM enables you to acquire machine-, process- and quality-data from a wide range of Siemens Sinumerik controllers and integrate the data seamlessly with your business information systems. It also allows to write and change parameters on these devices.
In general data acquisition from a remote PC is possible from Siemens Sinumerik series 840D and 828D controllers that have an Ethernet network connection. Communication with these devices is performed via the OPC protocol. The first thing you have to do is to find out which standard is supported by your controller as there are two different OPC standards used, ‘Classic’ and the newer ‘Unified Architecture (UA):
Controllers with Microsoft Windows OS that do NOT run Sinumerik Operate >= 4.5 SP3 most likely use OPC Classic which is based on Microsoft's COM/DCOM technology. For setup your controller, test data acquisition, monitoring and writing of parameters you can use the CNCnetPDM OPC DA Classic client which can be found here: https://www.inventcom.net/support/siemens/sinumerik-840d-opc-da-classic
