Use of CU2508 port multipliers
TwinCAT versions < TwinCAT 3.1.4024
The CU2508 may only be used on the EtherCAT Master side (see also Cabling). If this is the case, the option Using CU2508 must be activated in the Settings tab.
TwinCAT versions > TwinCAT 3.1.4024
The CU2508 may only be used on the EtherCAT Master side (see also Cabling). The EtherCAT simulation device automatically detects that a CU2508 was used on the master side. The option “using CU2508” is therefore no longer necessary
Notice | |
Incorrect values in the EtherCAT diagnosis If a CU2508 is used on the slave side, it is not contained in the TwinCAT project that exports the configuration file. In addition, this CU2508 only receives the EtherCAT frame after the EtherCAT simulation device. It is thus “invisible” to the EtherCAT simulation device. Consequently, neither the Device State nor the Slave Count on the EtherCAT master side display correct values. An EtherCAT diagnosis programmed in the original project thus displays incorrect results. |
