Input n - - - - DI4 DI3 DI2 DI1
NOTE
With PROFIBUS, PROFINET and CANopen, the I/O data of this module is localized within
the process data of the whole station via the hardware configuration tool of the fieldbus
master.
For DeviceNet, EtherNet/IP and Modbus TCP a detailed mapping table can be created with
the Turck BL20 DTM in PACTware.
