Description
U-ONE Generation II (LWL) – communication module PROFINET
UO-EPN / UO-SPN
System solution U-ONE(-SAFETY)-LWL
- UO-SPN-1: Communicates safe position and speed to a safety controller via PROFIsafe protocol
- UO-EPN-2: Communicates position and speed to a standard controller via PROFINET IO
- Resolution 13 bit singleturn / 15 bit multiturn
- Options: Without SIL/PL certification (UO-EPN-2); it is possible to combine 2 bus modules within a system
U-ONE Generation II (LWL) – communication module PROFINET
The communication modules of the U-ONE(-SAFETY) second generation transmit the position, speed and status data of the shafts that need to be monitored to a higher-level controller. They feature a PROFINET IO interface. In the UO-SPN safety design (certified up to SIL 2 / PL 2), the programmable parameters reference the counting direction, the idleness tolerance, the preset value, the integration time and the size of the monitoring window. In the UP-EPN standard design, only the counting direction can be parameterized.
