7.6. Switching signal channels (SSCs) configuration
The IL transducer offers two digital ouput (SSCs):
• Logical, inside process data (bit0 and bit1), during IO-Link mode communication
• Physical, on pin 4 and pin 2 (*) of M12 connector, during SIO mode.
SSCs commute according to the overtaking (high or low) of threshold value(s) based on the main process data, that is pressure.
Logical and physical SSCs behave in the same way, according to different configuration possibilities.
(*) Physical SSC2 is not available in SIL 2 / PL d relay output version.
Each channel has its own sets of parameters:
• SP1: point of switch HIGH, defined in MU (it must be higher than SP2)
• SP2: point of switch LOW, defined in MU (it must be lower than SP1)
• LOGIC:
- High Active
- Low Active
• MODE:
- Deactivated: SSC is not enabled
- Single Point: only SP1 is used to determine the commutation of SSC (it's important to set Hysteresis)
- Two Point: SP1 and SP2 are used to determine commutation and contemporarily the hysteresis (no need to set
parameter Hyst)
Window: SSC commutes both during ramp up and ramp down, when pressure overtakes SP2 and SP1 threshold in both directions
• HYST: the hysteresis, always espressed in MU, is useful for:
-Single Point Mode: hysteresis value is all below SP
-Window Mode: hysteresis value is half above SP, half below SP
• SET_DELAY: filter on SSC activation; if the pressure spike/movement is faster than the time interval defined in set_delay
parameter (0,1s resolution) the SSC does not activate
• RESET_DELAY: filter on SSC deactivation; if the pressure spike/movement is faster than the time interval defined in reset_delay
parameter (0,1s resolution) the SSC does not deactivate
