5.3. Digital inputs.

Total number of digital inputs (DI1-DI16, DI_SYN1, DI_SYN2)
Of these, the number of digital inputs with synchronization function
(DI_SYN1, DI_SYN2)
Data entry modes
Program control of pull-up resistors activation:
- for inputs DI1-DI16
- for inputs DI_SYN1, DI_SYN2
Maximum speed in synchronous mode
Maximum speed in asynchronous mode.
Recommended operating voltage range
Operating voltage range
High-impedance state with power off
Maximum input current with power off
