7.1 Important notes for registers
NOTE
The highest number of registers, which can be read with a single command, are:
- ASCII mode: 63 registers
- RTU mode: 127 registers
- TCP mode: 248 bytes
NOTE
The highest number of registers, which can be programmed with a single command, are:
- ASCII mode: 13 registers
- RTU mode: 29 registers
- TCP mode: 1 register
NOTE
The variable indicated by YES in RESET column, resets the instrument. Wait at least 5 seconds
before sending a new query.
NOTE
The register values are in hexa format ($).
NOTE
The * symbol indicates a parameter available only when the instrument includes the relevant
option.
NOTE
Selecting Read Only protocol mode (RO), the unit sends data only in RTU format and it cannot
be programmed via serial port (see p. 7-3, 7-4).
NOTE
IEEE registers cannot be used in case of MODBUS TCP protocol.
