EXTENDED MODBUS REGISTERS: The traditional addressing of Modbus Holding Registers has been limited to
9999. However, since the actual address is contained in a 16-bit word, addresses above 9999 are available. Many
Modbus Masters support this extended addressing. Configuration data for a Sequencer & Timers contained in a
single sequencer loop can be accessed in this space. The actual loop that can be accessed is contained in the Modbus
parameter MSLCP Modbus Sequencer & Timers Configuration Pointer located in register 40041. This register
contains the Modbus Index for the loop that can be configured with these extended parameters. A small number of
these parameters have also been mapped in the areas listed within the actual loop area for those Masters that cannot
access the extended area.
In addition, there are a number of registers reserved for the mappings of Modbus registers used in the Peer-to-Peer
functionality of the Ethernet function blocks.
