Pump status registers
Registers in this block can be read by means of function codes 0x03 and/or 0x04. They are read-only.
Address Register name Description
201
StatusReg ---
b0..b5:
RESERVED
---
b6: Rotation
Indicates if the pump is rotating (running) or not.
0 = No rotation
1 = Rotation.
b7: RESERVED ---
Bit 8:
AccessMode
Indicates if the pump is locally or remotely controlled.
0 = Local (a source with higher priority controls the pump)
1 = Remote (controlled by Modbus master).
Bit 9: IsOn
Indicates if the pump is on or o.
0 = O
1 = On
It not necessarily indicate rotation as an error might stop the pump.
Bit 10: Error
Indicates if there is a problem with proper operation.
0 = No problem
1 = Error present.
Pump might still run.
Bit 11:

---
Bit 12:
RESERVED
---
Bit 13:
NearMaxSpeed
Indicates if the pump is running near maximum speed.
0 = No
1 = Yes.
This ag is set when power or speed is over 95% of rated maximum.
Bit 14:
RESERVED
---
Bit 15:
NearMinSpeed
Indicates if the pump is running near minimum speed.
0 = No
1 = Yes.
This ag is set when speed falls below 1/3 of rated maximum.
202 RESERVED (TBD)
203 ControlMode
Indicates the actual control mode.
0 = ConstantRPM
1 = ConstantRPM
3 = ConstantHead
4 = ConstantHead
5 = ConstantHead
6 = ProportionalHead
128 = AutoHeadMode.
204 RESERVED ---
205 ErrorCode1
Current rst error code.
0 - when pump is operating without problems.
This value will always be non-zero when there is an error
present. See section “Error! Reference source not found. Error!
Reference source not found.” for code details.
206 ErrorCode2
Second error code. Non-zero when there is more than one error. See section
“Error! Reference source not found. Error! Reference source not found.” for code details.
207 ErrorCode3
Third error code. Non-zero when there is more than two errors. See section
“Error! Reference source not found. Error! Reference source not found.” for code details.
208 ControlMode
Indicates the actual control mode.
0 = AutoHeadMode (Automatic head mode)
1 = ProportionalHead (Head proportional to ow)
2 = ConstantHead (Head is kept constant)
3 = ConstantRPM (Speed is kept constant).
NOTE: values outside this range reserved.
See section “Error! Reference source not found. Error! Reference source not found.”
for exact parameter to be controlled.
