*to Pin 1 / Pin 8: These signals are only assigned from Order No. 6SL3040-0LA00-0AA1.
The associated temperature channel (T1) can be parameterized as an individual channel or
in combination with the second temperature channel (T2) at interface X120 (for
parameterization information, refer to the Commissioning Manual).
Re. pin 2 / pin 3: These signals are only assigned from Order No. 6SL3040-0LA00-0AA1.
