Function of the Digital Input
For the "Function DI" parameter, select one of the following functions for the digital input:
● Input
● HW gate (see section "Gate Functions in Measurement Modes (Page 72)")
Function of the Digital Output DO1
For the "Function DO1" parameter, select one of the following functions for the DO1 digital
output:
● Output (no switching by the limit-value monitoring)
● Measured value outside the limits
● Measured value under the low limit
● Measured value over the high limit
(see section "Behavior of the Output in Measurement Modes (Page 73)")
Values that Can Be Changed During Operation
● Low limit (LOAD_PREPARE)
● High limit (LOAD_VAL)
● Function of the digital output DO1 (C_DOPARAM)
● Integration time/update time (C_INTTIME)
(see section "Assignment of the Feedback and Control Interfaces for the Measurement
Modes (Page 75)")
