Note:
1. the power down holding area is marked with *1, and the flash area is marked with *2.
2: the address in the above table is used when PLC is the lower computer and Modbus RTU
or MODBUS ASCII protocol is used for communication, the general upper computer is:
SCADA/HMI/PLC.
3: if the upper computer is PLC, program according to Modbus RTU or MODBUS ASCII
protocol.
4: if the upper computer is SCADA or HMI, there are two situations: the first one has the
Xinje driver, for example: Xinje HMI / Zijinqiao SCADA.
The program can be written directly by using PLC internal soft components (Y0 / M0); for
the second type, Modbus RTU or Modbus ASCII is selected if there is no Xinje driver, and
then use the addresses in the table above to define the data variables.
5: input and output point is octal, please calculate corresponding input and output point
MODBUS address according to octal, for example: MODBUS corresponding to Y0,
the address is H6000, the Modbus address corresponding to Y10 is H6008 (not H6010), and
the Modbus address corresponding to Y20 is H6010 (not H6020).
6: when the Modbus address exceeds 32767, it needs to be expressed in hexadecimal, and "0"
should be added before the address. For example: MODBUS of HD0 is 41088 in decimal
(beyond 32767), and 41088 cannot be written into the software, so it needs to be expressed in
hexadecimal as H0A080.
7: Calculation of Modbus address of X and Y, taking X as an example, the calculation of
Modbus address of Y is the same as that of X.
X0: 20480 X10: 20480+8 X20: 20480+16 X30: 16384+24...
X10000: 20736 X10010: 20736+8 X10020: 20736+16...
X10200: 20800 X10210: 20800+8 X10220: 20800+16...
