Advanced Configuration Features

Reading Register All the registers in the data image can be read by an HMI panel connected to the

Dataisland at the NIM’s CFG port (See The CFG Interface, p. 33). The Advantys configuration software reads all this data, and displays blocks 1, 2, 8 and 9 in the Modbus Image screen in its I/O Image Overview.

Writing Register Some registers, usually some configured number of registers in block 9 (registers

Data49488 through 49999) of the data image, may be written to by an HMI panel (See HMI Panel Configuration, p. 170).

The Advantys configuration software may also be used to write data to the registers in block 1 (registers 40001 through 44096). The configuration software must be the island bus master in order for it to write to the data image—i.e., the island must be in test mode.
