  The hardware address of the ESP power supply device adopts the “8421BCD” code dialing code:
 
  The DIP switch is set to 1 (8421BCD code), and the corresponding device address is set to 1;
 
  The DIP switch is set to 2 (8421BCD code), the corresponding device address is set to 2, and so on.
 
  When multiple devices communicate, the addresses cannot be the same, and the dialing settings are recommended to be continuous.
 
  If Ethernet communication is used, port number 502, dial switch is the same as above, and the device IP address is correspondingly:
 
  The DIP switch is set to 1 (8421BCD code), and the device IP address is 192.168.4.161;
 
  DIP switch set 2 (8421BCD code), device IP address 192.168.4.162;
 
  The DIP switch is set to 3 (8421BCD code), the device IP address is 192.168.4.163, and so on.
 
  When multiple devices communicate, the addresses cannot be the same, and the dialing settings are recommended to be continuous.

  Note:
  1. For some systems, the address offset bit is 1.
  2. The write mode specifies that “write when there is change” is selected, and the “continuous write” mode is not allowed.
  3. Hollysys system: When adding an address, you cannot “create redundant address bits” (addresses that do not exist in the above table)。 When adding the first address to add the address length beyond the address bit provided above, if you delete again, the write error address will still appear.
