4.11 Mounting of Passive Terminals
Note
Hint for mounting passive terminals
EtherCAT Terminals (ELxxxx / ESxxxx), which do not take an active part in data transfer
within the bus terminal block are so called Passive Terminals. The Passive Terminals have
no current consumption out of the E-Bus To ensure an optimal data transfer, you must not
directly string together more than 2 Passive Terminals!
