SICK FX3-CPU000000 Flexi Soft Safety Controller Main Module
Description
FX3-CPU000000 is the SICK Flexi Soft main module (part no. 1043783) of the Flexi Soft modular safety controller, which executes the safety logic of a machine. The catalogue summary lists: module: Main module; configuration and diagnostics interface: RS-232 (M8 female connector, 4-pin); enhanced sensor functions: –; controller networking: –; connection type: Plug-in spring terminals.
How the FX3-CPU000000 works and where it fits
Configuration is stored in the system plug, a separate component that carries the configuration and the wiring terminal. The EFI interfaces connect SICK safety devices such as laser scanners and light curtains directly over a safe, two-wire bus, which removes the need for wiring each output separately and gives the controller diagnostic data from the devices.
Flexi Line and Flexi Link allow several controllers to exchange safe signals over a short distance without additional hardware, which helps with split machine lines. The program determines the response time, so verify it for the configured logic.

About brand
SICK is the German maker of industrial sensors: photoelectric and proximity sensors, safety laser scanners and light curtains, encoders, distance sensors, code readers and gas analysers. Erwin Sick, an optics engineer, founded it in Munich in 1946, and in 1952 it introduced its first marketable accident-prevention light curtain, which protected press operators by stopping the machine when a hand broke the light beam. The company moved to Waldkirch in the Black Forest in 1956 and is still headquartered there. It is a privately held company, and has been an Aktiengesellschaft (AG) since 1996.

Choosing a SICK sensor
For object detection, the sensing principle comes first. A retro-reflective sensor (WL series) sends light to a reflector and switches when an object breaks the beam; it is reliable over long distances and easy to align. A sensor with background suppression (WTB series) detects an object at a set distance and ignores what is behind it, which suits conveyors with shiny or dark backgrounds. A through-beam pair (WS/WE) gives the longest range and the highest reliability in dust. For transparent bottles and film, use a model built for transparent objects (for example WL12G-3B or WL150-P420). The digits in the code also matter: "P" usually means a PNP output and "N" NPN, and the last digits set the connector or cable. For machine guarding, a safety laser scanner such as nanoScan3 or microScan3 protects an area, while a safety controller such as Flexi Soft combines several safety devices.
Where SICK products are used
In Oman and the GCC, SICK sensors are used in packaging and bottling lines, food and beverage plants, logistics and airport baggage handling, cement and steel plants, ports and cranes, automated warehouses, and on machines built by European OEMs. SICK safety scanners guard robots and automated guided vehicles, and its encoders give position feedback on motors, hoists and conveyors.

Ordering SICK products: what we need
Send the type code and the 7-digit SICK part number from the label (for example WTB12-3P2431 together with its part number). For a replacement sensor, add the output (PNP or NPN), connection (M8, M12 or cable) and sensing distance. For encoders, add the interface (incremental, SSI, PROFIBUS, PROFINET), resolution and shaft type. For safety scanners, tell us the model and whether the existing configuration needs to be kept.
