5.7 Blocks for analog value functions
5.7.1 Triggered saving
Function
The block saves the current value of an analog input when a programmable event (Trigger)
occurs. With an edge change 0 → 1 of "Trigger" the value of the input is written to the output.
The "Reset" input resets the output to 0. As long as "Reset" is set to 1, the "Trigger" input is
ignored.

Trigger True / False
Digital input / output /
bit memory
STATUS_ERROR
With an edge change 0 → 1 block processing is started
and the value of "Input" is saved in the "Output".
With the setting "True" an edge change 0
→ 1 of the
trigger is evaluated in the first update cycle. The block is
processed only once.
With the setting "False" the block is never processed.
Reset True / False
Digital input / output /
bit memory
STATUS_ERROR
When there is an edge change 0 → 1 the output is reset
to 0.
With the setting "TRUE" the function is actually turned
off.
With the setting "False" the output is never reset.
