It is the mapping addresses the master assigns to the configured module parameters of the slave
on the following interface. It can be seen that the configured modules of the slave corrspond to the
starting number of D registers in OUTPUT and INPUT areas of the master PLC through the
interfaces above and below.
Address: it is the offset of the starting addresses in INPUT and OUT areas that the AH PLC CPU
assigns to the master module with the Unit: byte. If "Auto Addressing" is picked on the
following interface, Address will be counted automatically; if not picked, the offset address
can be input by manual, user could reserve the space for the mapping address of the
master and the original mapping relation between master and slave keeps unchanged
when the length of the slave parameter is modified.
The counting of the starting D register in the master PLC corresponding to the configured module
of the slave:
The starting number of the D registers in OUTPUT area of the master PLC corresponding to the
slave configured module = the starting address in OUTPUT area + (Address/2).
The starting number of the D registers in INPUT area of the master PLC corresponding to the slave
configured module = the starting address in INPUT area + (Address/2).
The above is explained based on the connection of the master and AH10PFBS-5A slave. The
mapping relations between D registers in the master PLC and the configured modules of the slave
are related with the master parameters settings. For more details, please refer to section 10.3.3 in
the help.
