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.
*1
T/C registers are read only.
4. 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.

NOTE:
1. EV5000 in the DB register corresponds to the definition of S7-1200 software, the absolute address of DB,
rather than the global symbol DB.
