2. For ASCII or RTU mode, ELC COM2 stores the data to be sent in D1256~D1295, and stores
the command reply in registers starting from S , and stores the converted 16-bit data in D1296
~ D1311. M1131=ON when ELC starts converting to hexadecimal and M1131 = OFF after the
conversion is complete.
3. Use MOV, DMOV or BMOV instructions to move the hexadecimal data from D1296~D1311
and store in D-registers.
4. After receiving data, the ELC will automatically check if the received data is correct. If there is
any fault, M1140 = ON and the fault code will be stored in D1130.
5. After M1140=ON or M1141=ON, the ELC will re-transmit the data to the drive. If the received
data is correct, M1140 and M1141 will be reset.

Handling received data
ASCII mode : received data is stored in 16 consecutive registers that start from D0 with ASCII format
when in ASCII mode. ELC will convert the content to hexadecimal and store in registers
D1296~D1311 automatically
RTU mode : received data is stored in 8 consecutive registers that start from D0 and specified by
users in hexadecimal type in RTU mode
Receiving data completed and reset flag
