AH500 Module Manual
The second case: The window is as below after the DeviceNet master has assigned the starting
address to AHRTU-DNET-5A (that is, AHRTU-DNET-5A has been pulled into the scan list).
The starting address of each module can be set here. If the value in Start Address is set to 1006,
it means that the mapping starting address of the module is D1006.
If the starting address assigned to AHRTU-DNET-5A is D1005, the offset of the starting address
of the module is ##+1, that is equal to, D1006. If AHRTU-DNET-5A is removed from the scan list,
it means the DeviceNet master does not assign the starting address to AHRTU-DNET-5A and
the starting address D1006 of the module will show the offset ##+1.
