Note:
The "DI Counter (0x10)" and "DI Frequency (0x40)" record data as a 32-bit value and are
transmitted as two 16-bit registers. Consequently, the register's address has an offset of 2, i.e.,
the address of the second channel will be at the starting address +2, and so on. You can refer to
"FAQ_How do I read DI Counter for the PETL/t(P)ET/ET-2200 Series Modules correctly"
detailed information.
Example: Reads the 6 DI Counter on the ET-2260.
