• The multistate process value is mapped so that the mapping table specifies one or
more outputs to be driven.
• It is possible to have several active outputs, but only in a fixed combination.
• Examples: Enabling additional electrical heating or burner stages

In the case of bus failure, with DC 24 V module supply available, the following backup
states van be parameterized:
– No (Inactive) (= default)
– Value (Active, Inactive)
– Keep Same value as before the bus failure
Parameterization can be done during runtime.
• The I/O status LEDs indicate the activity of the relays
• In the case of an error the module status LED and all the I/O status LEDs assigned
to the function flash.
