DI: Digital input; DI/DO: Bidirectional digital input/output; M: Electronics ground;
1)
M1: Ground reference
B = Bidirectional; I = Input; GND = Reference potential (ground)

Note
An open input is interpreted as "Low".
Terminal M1 must be connected for the digital inputs to function. The following alternatives
are available:
 Connect the incorporated ground reference of the digital input to M1.
 Create the bridge between terminal M and terminal M1.
