13.3 Message types
The message types are basically differentiated into:
Process error messages
System error messages
Process error messages
The programmer determines the repertoire of messages in the
Signal List
(see chapter
defines there the priority with which the respective messages should alert.
The example shows that when the potential-free
NC contact
IX0.2 opens (terminals 54/55), i.e. the process
variable "_E_FST" changes from High to Low, a "
frost protection thermostat
" alarm is sent with priority 0.
Assuming that the contact is processed further in the application by a function block and this sets the variable
MA_FST_ERR, a "frost protection alarm" is then sent with priority 2.
