Characteristics

Compliant with the EtherCAT protocol, RTU-ECAT supports PDO, SDO and other services in the COE

protocol.
Supports Distributed Clock SYNC and SyncManagers SYNC.

On its right side, RTU-ECAT connects DVP-S series right-side modules with maximum 128 digital input

points and 128 digital output points as well as maximum 8 special modules such as analog modules,
temperature modules, pulse modules and etc.
Maximum 14 DVP-S series digital modules and special modules in total can be connected to the right

side of RTU-ECAT.
Users can select that the output values of right-side special modules and digital output point values of

digital modules keep the same as they are before disconnection or change to zero when RTU-EtherCAT
is disconnected from the master.
