ENIP-2 can contain up to 32 DI. These include its own DI (built-in) as well as DI from
extension ENMV modules connected to ENIP-2 via RS-485-2 (up to 4 modules).
ENIP-2 has events log of DI statuses. Each record of event log is marked with time stamp
with 1 ms resolution.
DI statuses are transferred over IEC 60870-5-101, IEC 60870-5-104 in Single point or
