Program Example 7: COM2(RS-485), Function Code H06
1.
Function code K6(H6) : write one data word
ASCII Mode when M1143=OFF
RTU Mode when M1143=ON
2.
When in ASCII mode, store the data that will be written to the drive in ASCII format in register
D50. Data received from the drive will be stored in registers D1070~D1076.
3.
When in RTU mode, store data that will be written to the drive in hexadecimal format in register
D50. Data received from the drive will be stored in registers D1070~D1077.
4.
When in ASCII or RTU mode, the ELC will transmit the data stored in registers D1256~D1295.
5.
After receiving a response, the ELC automatically checks if the received data is correct. If
there is any fault, M1140 will be set to ON.
6.
If the register address of the drive is illegal, a fault code will be stored in D1130 and M1141 =
ON. For example, 8000H is illegal for the drive and M1141=ON and D1130=2. Refer to MVX
user manual to fault code.
7.
After M1140=ON or M1141=ON, the ELC will re-transmit the same data to the drive. If the
received data is correct, M1140 and M1141 will be reset.
