An F-DI consists of a digital input and a 2nd digital input where, in addition, the cathode of the optocoupler is fed-out.
F-DI 5 = terminals 2, 3 and 6
F-DI 6 = terminals 4, 5 and 7
Type: Screw terminal 1 (Page 288)

Note
Execution of a test stop
The test stop of the F
-DI 5 to F-DI 9 can only be performed if the F-DI is supplied from L2+.
Note
Ensuring the function of digital inputs
For the digital inputs DIx+ to function, the reference potential must be connected to input
DIx
- in each case.
This is achieved by using one of the following measures:
1.
Providing the ground reference of the digital inputs
2.
A jumper between DIx- and terminal M1
