If you are trying to catch alarms, then you must use the OPC Alarm & Event interface instead

There is a lack of public siemens documentation about the OPC features and issues. I can not really understand why. You can easily find a lot of information on SIMATIC systems but not SINUMERIK. It seems you are required to by the HMI-Programming package in order to get it.

Keep us posted about your progress. I wish you the best of luck...

Hi Max,

The usual example is to read out the operating mode of the mode group (BAG).In this case you would add an opc item with
ItemID: "/Bag/State/opMode[u1]"
where "[u1]" is optional

To read out the machine axis position of the first axis in channel
ItemID: "/Channel/MachineAxis/actToolBasePos[u1,1]"
where "u1" refers to channel 1
and the second parameter is machine axis number

To read out the tool edge center postion in work coordinates for a geometry axis
ItemID: "/Channel/GeometricAxis/actToolEdgeCenterPos[u1,1]"

where "u1" refers to channel 1
and the second parameter isnumber of geometry axis (1 is usually X axis)

I hope this will help you
