Hello, 

I have the following variable frequency drive, in the hardware configuration of a TIA V17 project:

Sinamics G120 PN [6SL3210-1KE24-4UF1]:

Generally, this VFD has an embedded Analog Input port (AI 0+  AI 0-):

In my project, I would like to connect a sensor to that port (which outputs 4...20mA signal) then use this AI value in other project's tasks. In TIA hardware configuration, I have tried to find the location of that AI port within the VFD GSDML: I have only found the following I/O configuration where it is "supposed" to be the interface of the drive's peripheral ports(I/O):

What I intend to achieve is, to be able to write a tag name for the sensor's input as Int (just like in the case of having a remote PN I/O device such as IM155), on the drive's AI port. 

Could you please tell me how to do that? Must I add to the VFD GSD another sub-component which represents its DI and AI ports?

Thanks

how about trying to expand communication

 Hi and thank you,

This is my very first interference with Sinamics drives. So they interact with the CPU (send/receive) via "Telegrams". Could you please recommend a startup/introduction to Sinamics articles/samples?

Or if possible, a small description of such devices, operation principle, what are telegrams and why there exist many types of them, how to address the I/O of the drive's periphery, etc.

Whenever you need to know something about details of Sinamics functionality (or in general Siemens drives) look for its List Manual.

 Thank you
