4.6.4 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:
• Safety Integrated Basic Functions via the EP terminals
• Safety Integrated Extended and Advanced Functions via onboard I/Os (3 F-DI and 1 F-DO)
• Safety Integrated Extended and Advanced Functions with TM54F
• Safety Integrated Basic and Extended/Advanced Functions via secure communication from
"PROFIsafe on PROFIBUS"
Control (F logic) is via a SIMATIC F-CPU which is connected to PROFIsafe via PROFIBUS (not
SCOUT TIA).
• Safety Integrated Basic and Extended/Advanced Functions via secure communication from
"PROFIsafe on PROFINET" (only for SIMOTION D410-2 DP/PN)
Control (F logic) is via a SIMATIC F-CPU which is connected to PROFIsafe via PROFINET (e.g.
an S7-1500 F-CPU).
For further information on Safety Integrated, see the SINAMICS S120 Safety Integrated Function
Manual.
EP terminal
The pulse inhibit function (EP) is only available when Integrated Basic Functions are enabled.
Digital inputs (DI)
The SIMOTION D410-2 provides ve digital inputs (DI).
