Control of the Extended/Advanced Functions via F-DI (for CU310-2)

The following terminals are provided on the CU310-2:
Table 5- 18
Type
Failsafe digital outputs (F-DO)
Failsafe digital inputs (F-DI)
Sensor
Digital input for checking the F-DO for the forced checking procedure (test
stop)
Sensors: Failsafe devices for command operations and sensing (e.g. Emergency Stop pushbut-
1)
tons, safety door locks, position switches, and light arrays / light curtains).
The CU310-2 has 1 failsafe digital output and 3 failsafe digital inputs. A failsafe digital output
consists of a 24 VDC switching output, an output switching to ground and a digital input for
reading back the switching state. A failsafe digital input is made up of 2 digital inputs.
Note
Fault acknowledgment
You have the following options of acknowledging CU310-2 faults after removing the fault:
• POWER ON
• Falling edge of the signal "Internal Event ACK" with subsequent acknowledgment on the
Control Unit ("failsafe acknowledgment").
The signal states of the two digital inputs of the F-DI are frozen at logical 0 (safety function
selected) when different signal states are present within a failsafe F-DI, until a safe
acknowledgment has been performed through an F-DI via parameter p10006 (SI
acknowledgment internal event input terminal) or the extended message acknowledgment
has been performed.
