The data map addresses of Weidmüller switches shown in the following table start from MODBUS
address 30001 for Function Code 4. For example, the address offset 0x0000 (hex) equals MODBUS
address 30001, and the address offset 0x0010 (hex) equals MODBUS address 30017. Note that all
the information read from Weidmüller switches are in hex mode. To interpret the information, refer to
the ASCII table for the translation (e.g. 0x4D = ‘M’, 0x6F = ‘o’).
