NivuSonic Clamp on
Example (Address 6):
-
Bit0 Æ Status Flow
-
Bit1 Æ Status Level
-
Bit2 Æ Status Velocity
-
Bit3 Æ Status Water temperature
-
Bit4 Æ Status Air temperature
Holding Registers
Function Code(s):
-
“Read Holding Registers” (0x03)
-
„Write Single Register“ (0x06)
-
„Write Multiple Registers“ (0x10)
Address:
-
1-8: Analog Outputs 1-8 (scaled)
-
9: Digital Outputs 1-16
Note:
A write operation on these addresses has an effect on the respective output only
if the output parameter has been set to "Modbus" under
PAR > analog Outputs
> Function
on the unit previously.
A read operation will return the status previously set, which however not neces-
sarily must correspond with the physical output status.
Discrete Inputs
Function Code(s):
-
“Read Discrete Inputs” (0x02)
Addresses:
-
1-16: Digital Inputs 1-16
-
17-32: Digital Outputs 1-16
-
33-64: Error messages 1-32
Note:
Reading the addresses 17-32 returns the physical state of the digital output.
Importance of the several error messages (Addresses 33-64):
-
1: real time clock
-
2: serial interface
-
3: analog inputs
