Description of function
This special function saves the process variable of an
analogue input to memory and returns it at the analogue
output.
Connection
Description
Input S ( )
Save the Ax to memory and return
it at the analogue output with a
signal at input S (Set).
Input Ax
Input the analogue signal to be
amplified at input Ax. Use the
analogue inputs, the block number
of a function with analogue output,
or the analogue outputs.
Input R ( )
Reset analogue output AQ to 0
with a signal at input R (Reset).
analogue Output AQ is reset if S
and R are both set (reset has
priority over set).
Parameter
Value range for Start value: -
32768...+32767
Output AQ
Analog output
Value range for AQ: -
32768...+32767
Example
When I1 is HIGH, the value of AI2 will be saved to memory
and sent to AQ1 as follows:
