Generally, after factory facilities are shut down, it takes a lot of time to restart them.
PROFIenergy enables PROFINET communication to continue while saving energy by minimizing restart times. When the commands for PROFIenergy energy-saving mode are sent from the I/O controller (PLC) to the I/O device (SI unit), information regarding downtimes is also sent (such as lunch breaks, nighttime, weekends, and holidays).
SMC SI units do not require time for restarting. However, for the connected I/O equipment, such as pressure switches, flow switches, auto switches, and valves, 3 types of energy-saving modes are available for customers to choose from depending on the application.

An I/O module connected to an SI unit can be controlled by multiple I/O controllers (PLC).

・Information can be shared with up to 3 controllers in addition to the control PLC.

・The cost of the hardware, cables, and installation space can be reduced.

Passed and certified under the highest network load (Class Ⅲ) specified by PROFINET.

・2 power connectors and 2 communication connectors are mounted, making daisy-chain connection possible.
・An external branch connector is not necessary. Reduced wiring space
・Loop through current between power connectors: Max. 16 A^*

* The max. allowable current for the 7/8 inch power supply connector is 10 A. The max. loop through current between connectors is 6 A.

This feature continuously monitors the received light intensity from the fiber-optic cable and reports it to the PLC. Any loss of intensity is an indicator of damage to the cable, so may give a warning before communication is lost. By using preventative maintenance, you can avoid unexpected shutdowns.

The aim is to facilitate a safe design (featuring ISO/IEC compliance) of the customer’s equipment and facilities. The EX245-FPS□ has been certified under the following categories by a third-party organization (TÜV Rheinland).

The EX245-FPS□ has safety outputs inside the product that can control 3 zones for valves and 1 zone for output modules individually. When the safety switch is turned OFF by directive from the PLC, the voltage supplied to the valve or output module is shut off, and it switches to safe state. The safety switch of this product has two redundancies, one on the 24 V side and the other on the 0 V side. It continuously runs diagnostics. The safety switch is turned OFF in the event of an error detection.

The EX245-FPS□ is equipped with safety inputs. The safety inputs of this product can connect to components (e.g. laser scanners, light curtains, etc.) that are compatible with the safety inputs. The safety input can be loaded in 2 ways:
　・Single channel (1 out of 1): 8 safety inputs (SIL 2/PL d)
　・Dual channel (1 out of 2): 4 safety inputs (SIL 3/PL e)
