In columns A and B (Source) the slave device node address and register addresses can be
entered. This can be one continuous block or if more than one slave device is used up to 16
devices can be set up.
The RTK 725B expects each block to be continuous, any unused block addresses must be filled
in with an unused “u” symbol.
Extensive use of the unused indication is to be avoided since it will consume valuable mapping
resource. This can be done by using multiple master blocks within the same node.
Block = Slave node with a range of internal addresses
The example below shows one block with gaps.
1st block has node address 1, start register 40001 and 10 registers
with registers 40007 and 40008 unused.
This will use 2 mapped points as the final 2 channels are no longer one to one.
The example below shows the same data addresses split over two blocks.
1st block has node address 1, start register 40001 and 6 registers
2nd Block has node address 1, start register 40009 and 2 registers
This uses no mapped points.
The example below shows 3 separate blocks with one block with gaps.
