HELP! How to read this kind of register
#7
Hi,

Could any of you help me? I need help with registers 138-139. It's a BITMAP32 register, where 0-15 are read as LSW and 16-31 are read as MSW (see example below), how are these parameterized in the modbus profile? I also attached the manual and the modbus profile I made. Thanks!


 
0x00100071 > Byte 1  ( 0x00 ), Byte 2 (0x71), Byte 3 (0x00), Byte 4 (0x10)
MSB, LSW                   


MSB: Most significant byte first
LSW: Least significant word first
 
In That example the following bits are set(counting starting at 0):
  • 0 sensor error
  • 5 pump 1 alarm
  • 6 pump 2 alarm
  • 7 pump 3 alarm
  • 20 net supply
