Modbus Holding Registers
There are sixteen Modbus holding registers for each SureCross ™ device. Calculate the holding register number for each device using
the equation: Register number = I/O# + (Node# × 16).
Because the Gateway is always device 0, the Gateway’s holding registers are registers 1 through 16. Registers for Node 1 are 17
through 32, as shown in the Modbus Holding Register table below. Though only ten Nodes are shown, the table can continue for as many
Nodes as are used in a given network.
Using the equation or the Modbus Holding Registers table, the register number for I/O point 15 for Node 7 is 127.
