PROFIBUS DP Communication

After M0.0 is set, the function block reads F0‑02 (Index 0 has been set to F0‑02 before)
of the AC drive No. 3 and saves it in QW6. The fields are defined as follows:
● REQ: Command enable. When this field is set to 1, the function block is enabled.
● ID: Logic address. To specify this field, convert any Q address of the corresponding
AC drive slave to a hexadecimal value, and set bit 15 of the value to 1. For
example, for Q512, the hexadecimal value is H200. After bit 15 is set to 1, H8200 is
obtained.
● INDEX: Index number, ranging from 0 to 5. This field can be customized to an index
mapping address of a slave as required.
● MLEN: Maximum length of the data to be obtained. For MD38DP2, this field must
be set to 2.
● RECORD: Target area of the obtained data record. This field is used to store read
data when the read operation is performed and sent data when the write
operation is performed.
