5.6.12 Position sampling (on−the−fly measurement)
A local digital input (IN1 or IN2) not occupied by the referĆ
ence or limit switch can be used as a fast sample input. With
a falling (depending on configuration: a rising) edge at the
configured sample input, the current position value is written
into a register of the SFC−LACI and can afterwards be read out
(PNU 350 or 351) by the higher−level control system (PLC/
IPC).
Overview of parameters for position sampling (on−the−fly measurement)
Parameter / Description PNU FCT CI
Input that is going to be used for the position sampling:
Value = 0: none / value = 1: IN1 / value = 2: IN2 1305 x 6510/16h
Trigger mode:
Ĉ Value = 1: cyclic" (continuous) = record position for every rising (deĆ
pending on configuration: and/or falling) edge
Ĉ Value = 2: single" (one−time) = record position only for the first rising
(depending on configuration: and/or falling) edge
352 x 204A/01h
Edge status:
Ĉ Value = 0: An edge was not registered. Writing 0 resets both edge
events to 0.
Ĉ Value = 1: A falling edge has occurred and a new position value was
stored.
Ĉ Value = 2: A rising edge has occurred and a new position value was
stored.
Ĉ Value = 3: A rising and a falling edge have occurred, the respective
position values were stored.
