SICK Flexi Loop User Manual

Unsafe inputs and outputs also make it possible to evaluate certain situations (e.g. con‐
t
amination) on the monitored system or to trigger functions (e.g. illumination of lamps
and activation of door locking devices).
Special features
•
up to 32 Flexi Loop nodes per safe sensor cascade
•
up to 100 m between Flexi Loop nodes and up to 3,200 m total length of the safe
sensor cascade
•
up to 10 m cable length between the Flexi Loop nodes and the devices connected
•
optional status indication via DIAG Flexi Loop accessory
•
optional power supply by means of PWRI power supply accessory
•
enclosure rating IP 65 and IP 67 to EN 60529
Connection to safety controllers:
•
Flexi Soft safety controller
•
Flexi Classic safety controller
•
up to 8 safe sensor cascades on one Flexi Soft safety controller
•
up to 48 safe sensor cascades on one Flexi Classic safety controller
3.1.1 System requirements
Flexi Soft safety controller
The saf
e sensor cascade is connected directly to a Flexi Soft safety controller extension
module. The following prerequisites apply:
•
one main module
°
FX3-CPUx with firmware V3.xx or higher
•
one or more expansion modules
°
FX3-XTIO with firmware V3.xx or higher
°
FX3-XTDI with firmware V3.xx or higher
°
FX3-XTDS with firmware V3.xx or higher
Flexi Classic safety controller
The saf
e sensor cascade is connected to the main module or a Flexi Classic safety con‐
troller extension module with a Flexi Loop MSTR accessory. The following prerequisites
apply:
•
one main module
°
UE410-MU version 13.45 or higher
•
one Flexi Loop MSTR1 or MSTR2 accessory
•
one or more extension modules (optional)
°
UE410-XU version 13.45 or higher
°
UE410-8DI version 13.45 or higher
3.1.2 Safety by means of Flexi Loop
•
P
erformance level up to PL e
°
dependent on the performance level of the overall application
°
independent of the number of Flexi Loop nodes and thus the number of sen‐
sors / switches
°
independent of whether the sensors / switches are directly connected to the
safety controller or to the safe sensor cascade
•
one cut-off path; the status of this path is represented in the Flexi Soft logic by
means of a single safe bit. This feature permits quick, safe shutdown.
•
no error masking
