RTU mode
address 011
Information in the Well Watch is accessed by register number using Modbus function 3
to read registers, 6 to write registers, or 16 to write multiple registers. It should be
noted that well watch registers are 32 bits wide and may represent integers or floating
point data. By default, Modbus assumes registers are 16 bits wide, and transmitted in a
character stream with bits 8-15 in the first character and bits 0-7 in the second. To
transfer a 32 bit register, the Well Watch assumes two 16 bit registers are transmitted
with the low order 16 bits in the first register then the high order.
The addresses are listed below.
All of the Well Watch data is sent as 32 bit words as either floating point
representations or as integers. The master device needs to be set accordingly.
