READING TORQUE VALUE FROM V-90 TO S7-1200 VIA PROFINET

Hello,

if you really want to read it acyclically I would recommend to use for example the SINA_PARA(_S) FB from the drive lib. The lib is always installed to TIA if Startdrive is installed. If not, you can download the lib from here:

The block is quite simple. Just follow the instruction of the manual. Important is to set the HW_ID correctly and the AxisNo (for V90 it is 1 or 2 - depending on the parameter - for r27 it should be Axis No. 2).

In the instance DB you set which parameter and which index you want to read. If the parameter is not indexed in the parameter list you just set the index to "0".
