13.9 Digital variables
The multifunction panel can manage and record 54 digital variables. The digital variables relate
to inputs or signals that are received via one of the multifunction panel interfaces (RS232,
RS422/485, setup interface, or Ethernet).
For example, the digital variables are pooled into groups together with other digital signals via
the "Groups" configuration and are available for further use via these groups.
Digital variables are always active. If no value has yet been received, the variables contain the
value 0.
