on fieldbus Please note: The CS31 bus interface occupies one or two module addresses (if counters are configured onboard
or if the module is a mixed digital analog module). Depending on the configuration, or if the module contains
also mixed digital analog I/O, connected extension modules can occupy further module addresses.
Configuration Using configuration tool (included in Automation Builder software suite)
Station address configuration No Using rotary switches (99 max.)
