Writing a program to Ormec Smlc 160
I have variables in "Retain"
Variables like pump speed and temperature set points
When I reset the PLC, all the values come back.
Doing cold reset through codesys also same thing
But when I power down (manually), the variables don't come back.
Why is that?
I've tried putting the variables in "Retain Persistent" and still the same thing.
Under target settings I have checked load boot project automatically
What else can I try?
This is very important as I don't think the PLC will be able to recover from a power outage without an operator being present and certain pumps need to be on at all time

never used 'Ormec Smlc 160' so probably I would recommend to ask the
manufacturer of this plc if there is a NVRAM inside this plc.
This is needed to have the retain feature available.
