NOTE:
1. DBn_DBX, DBn_DBW, DBn_DBD is a custom block. First three data formats for data block number,
the address after the five, less than five former address zeros. To DB20.DBX23.4 example, EV5000
software addresses to DBn_DBX: 2000023.4
2. The initial address of DBm.DBW, DBm.DBD must be an even number.
3. Make sure that the data block defined in PLC should be more than the data block used in HMI. For
example, if DB5.DBW32 is used in HMI, user can’t define the data block up to DB5.DBW32, but up to
DB5.DBW34 or more.
