11.3.3 Programmable Pointer Registers Configuration
Modbus Programmable Pointer Register Setup Information:
• Programmable pointer register values refer to MODBUS registers.
• There are 16 pointer registers for each of the three channels. Not all 16 registers
need to be configured.
• A pointer register can be accessed by making a request to Modbus registers
FC00 ~ FC0F. Any of these 16 registers can be defined as the starting register
for the transaction. Any number of these registers can be accessed with one
Modbus transaction (provided that all registers being accessed are valid).
• To clear a pointer register value, CLEAR the value displayed on the web page
interface and click apply.
• To add a new pointer register value in an empty location, enter a valid non-zero
hexadecimal number (0000 is an illegal MODBUS address) and click “Apply”.
• Pointer register values are internally stored in nonvolatile flash memory, and will
be saved when the unit is powered off.
• Refer to section 10.6 for more information about programmable pointer registers.
