3.5.4 Use of the interfaces
Fail-safe digital I/Os (F-DI/F-DO)
The SIMOTION D410-2 provides three fail-safe isolated digital inputs (F-DI) and one fail-safe
isolated digital output (F-DO):
● An F-DI consists of a digital input and a second digital input to which the cathode of the
optocoupler is connected.
Each of the F-DIs can also be used as two standard digital inputs, e.g. the use of the F-DI
0 as DI 16 and DI 17.
● The F-DO 0 can also used as a standard digital output.
The F-DO 0 consists of a high-side switch and a low-side switch. For applications without
the safety function, the high-side switch may be used as an additional digital output. The
low-side switch is not available.
Note
The following safety functions are available for SIMOTION D410-2 DP:
• Safety Integrated Basic Functions via the EP terminals
• Safety Integrated extended functions via onboard I/Os (3 F-DI and 1 F-DO)
• Safety Integrated Extended Functions with TM54F
• Safety Integrated basic and extended functions via secure communication from
"PROFIsafe to PROFIBUS"
Control (F logic) is via a SIMATIC F-CPU which is connected to PROFIsafe via
PROFIBUS (e.g. a CPU 317F-2 DP)
For further information on Safety Integrated, see the
SINAMICS S120 Safety Integrated
Function Manual.
Digital inputs (DI)
The SIMOTION D410-2 provides five digital inputs (DI).
The electrically isolated inputs can be used as freely addressable inputs.
Note
An open input is interpreted as "low".
For the DI 22 digital input to function correctly, the coupled reference potential (DI 22-) must
be connected. The following options are available:
• Connect the coupled reference potential of the digital input to M1, M2 or M.
This assigns the input to the potential of the associated pin.
• Create a bridge between terminal M and terminal M1 or M2.
Caution: This will cancel the electrical isolation for this digital input!
