Hi list,
In a recently installed PLC (S7-300 CPU 315-2dp) several setpoints for controllers, alarmvalues, max. speedvalues, ... are stored in datablocks in the Actual value part. The initial value is not filled in. What happens during a restart (or after voltagedrop)? Are the initials copied to the actuals (so we loose all current setpoints ??) ? Is there a danger that we loose the actuals ? Is it necessary to have the same initial and actual value ???
Tx in advance,
JomO
