EtherCAT P
EtherCAT P supplements the EtherCAT technology with a process in which communication and supply
voltages are transmitted on a common line. All EtherCAT properties are retained with this process.
Two supply voltages are transmitted per EtherCAT P line. The supply voltages are electrically isolated from
each other and can therefore be switched individually. The nominal supply voltage for both is 24 V
DC
.
EtherCAT P uses the same cable structure as EtherCAT: a 4-core Ethernet cable with M8 connectors. The
connectors are mechanically coded so that EtherCAT connectors and EtherCAT P connectors cannot be
interchanged.
EtherCAT P Box modules
EtherCAT P Box modules are EtherCAT P slaves with degree of protection IP67. They are designed for
operation in wet, dirty or dusty industrial environments.
