Reading a TEDS module (e.g. on the K642) fails on STGMM CAN. What can be the reason for this?

The TEDS module can only be read out if the measuring bridge has been connected correctly. This can be recognized by the green channel LED. As long as this does not light up green, the TEDS cannot be read out either.

The MiniModules for strain gauge measurements (STGMM) require the 6-wire technology.
If a sensor with 4-wire technology is used, the sense wires must be connected to the supply voltage of the measuring bridge (Vsense+ to Vout+ / Vsense- to Vout-).

In addition, the module should be updated to the latest firmware version. The latest firmware is supplied with the latest CSMconfig or can be found on the homepage.
