Inputs/outputs
Digital inputs:
hide
Display suppression (with hide = 1 the page in the operation is not displayed).
disable The digital input can be used to interrupt automatic or triggered sampling (high-active).
reset The digital input deletes the shift register and resets trend measurement.
sample
If the digital input is wired, sampling is triggered by a positive flank (0 r 1) at this input. In this case, the ad-
justed sampling interval (configuration) is not effective.
Digital outputs:
ready
After filling the shift register with 100 values first, the digital output is set to high.
Analog inputs:
x1
Process value to be displayed as trend (default = 0)
Analog outputs:
X-100
The value of the shift register which is overwritten by the next sample value is provided at the analog output
(value 100 samples ago).
