4 EtherCAT features supported by BL20
4.1
EtherCAT according to the Modular Device Profile
The EtherCAT gateway for BL20-ECO complies to the EtherCAT Modular Device Profile (MDP)
according to EtherCat-standard ETG 5001.
The BL20-ECO gateway for EtherCAT supports CANopen over EtherCAT (CoE).
A Modular Device is a device with physically connectable modules and/or several functional mod
-
ules. Therefore only one object dictionary exists in the gateway.
Each BL20-I/O-module has corresponding entries for inputs, outputs, configuration, information,
RxPDOs and TxPDOs.
According to the MDP, two defined areas exist in the object dictionary:
Communication Area
Device Parameter Area
The object dictionary is dynamic and always depends on the modules, which are physically con
-
nected to the gateway. The object dictionary is created in the device‘s RAM on each power cycle.
There is only one object dictionary for the complete station.
NOTE
File Access over EtherCAT (FoE), Servo Profile over EtherCAT (SoE) and Ethernet over Eth
-
erCAT (EoE) are not be supported, yet.
