Configuring
with the
MODBUS
Protocol
When powering up the instrument, the pump will automatically turn on
after 3 seconds, and it will begin sampling using the default
configuration:
• Location = 0
• Sample Time = 60 seconds
Note:
For the full
MODBUS v.1.45 register
map, please refer to
Appendix B.
• Hold Time = 0 seconds
• Initial Delay = 0 seconds
Note:
The automatic
starting of the sampling
accommodates systems
that do not send a START
command, but just polls
the instrument for its data.
To stop the pump and the sampling, send the command 12 to command
register 40002.
