Data Byte Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
Input n DI8 DI7 DI6 DI5 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.
