GHM Delta OHM PYRAsense LPS10 Series User Manual

LPS10 - 16 - V1.0
7 MODBUS-RTU PROTOCOL
By default, the pyranometer has Modbus address 1 and communication parameters
19200, 8E1. The address and the communication parameters can be changed by using
the appropriate serial commands of the proprietary protocol or, alternatively, directly
with Modbus commands by changing the value of the Holding Registers described lat-
er.
The Modbus-RTU protocol is active after a few seconds from the sensor power on.
Below is the list of registers.
Input Registers:
