Precautions for Correct Use
If you edit the PDO mappings in a PDO entry table (data type: BOOL), add padding (index:
0x0000:00) in order to adjust the data size of the PDO mappings to the byte boundary of 8
bits.
Additional Information
For more information on the assignments in the input and output areas, refer to
4.2 SDP
Default PDO Mapping
of the
Kashiyama Dry Vacuum Pump EtherCAT Communication
Specification
(TDA-00135-01).
Additional Information
The device variables are automatically created by combining the device name and the port
name. The default device names are "E" followed by a serial number starting from "001".
