NAVIPASS Modbus - Accessory
Example: to set the configuration 8 bits / 1 Bit stop / no parity and 9600 baud => 1-0-2-3
It is therefore necessary to write 1023 in hexadecimal or 4131 in decimal.
A factory reset (press for 10 seconds on any of the buttons) resets the configuration
with the value 0x1025.
3.3. Adjusting the "time out" of response via the register 0x0009
The response time of the boiler varies based on your installation. Thus, to optimize
response times and avoid obtaining Modbus errors N°06, you can modify the Time out.
During a query by the PLC, the Modbus NAVIPASS:
- either will respond immediately with an error code (wrong address, wrong
- or will give the response to the question. If the boiler does not respond to

CAUTION:
INFORMATION:
The response is stored in the NAVIPASS Modbus

During a power failure, the value of the time out
is automatically re-initialised to 5000 ms (factory

The time out set in the Modbus NAVIPASS must be
lower than that set in the PLC.
