PUMP_ID	R/W	Numpad- value 1 to 3	ID of the pump for which the Function Block is to be called.
INLET_CTRL	R/W	Numpad – value 0 to 3	To enable control for primary protection against low inlet pressure: 0 = disabled, 1 = alarm, 2 = Fault, 3 = reduced speed.
PRESSURE_LOW_LIMIT	R/W	Numpad – value 0.0 to 100.0	Low pressure level limit for primary protection.
PRESSURE_VERY_LOW_CTRL	R/W	Numpad – value 0 to 2	To enable control for secondary protection against very low inlet pressure: 0 = disabled, 1 = fault, 2 = stop.
PRESSURE_VERY_LOW_LIMIT	R/W	Numpad – value 0.0 to 100.0	Very low pressure level limit for secondary protection.
INLET_CTRL_DELAY	R/W	Numpad – value 0 onwards	Delay in seconds for primary and secondary supervision to start. 0-600 s.
INLET_FORCED_REF	R/W	Numpad – value 0 onwards	Safe speed reference for the drive when the INLET_CTRL = 3 i.e. reduced speed mode.
OUTLET_CTRL	R/W	Numpad – value 0 to 3	To enable control for primary protection against high outlet pressure: 0 = disabled, 1 = alarm, 2 = fault, 3 = reduced speed.
PRESSURE_HIGH_LIMIT	R/W	Numpad – value 0.0 to 100.0	High pressure level limit for primary protection.
PRESSURE_VERY_HIGH_CTRL	R/W	Numpad – value 0 to 2	To enable control for secondary protection against very high outlet pressure: 0 = disabled, 1 = fault, 2 = stop.
PRESSURE_VERY_HIGH_LIMIT	R/W	Numpad – value 0.0 to 100.0	Very high pressure level limit at for secondary protection.
OUTLET_CTRL_DELAY	R/W	Numpad – value 0 onwards	Delay in seconds for primary and secondary supervision to start.
OUTLET_FORCED_REF	R/W	Numpad – value 0 onwards	Safe speed reference for the drive when the OUTLET_CTRL = 3 i.e. reduced speed mode.
FLOW_MAX_CTRL	R/W	Numpad – value 0 to 2	To enable control for protection against maximum flow condition: 0 – Disabled, 1 – Alarms, 2 – fault.
FLOW_MAX_LIMIT	R/W	Numpad – value 0 to 32767	Value of max flow rate limit in m:sup:3/h.
FLOW_MIN_CTRL	R/W	Numpad – value 0 to 2	To enable control for protection against minimum flow condition: 0 – Disabled, 1 – Alarms, 2 – fault.
FLOW_MIN_LIMIT	R/W	Numpad – value 0 to 32767	Value of min flow rate limit in m:sup:3/h.
FLOW_CTRL_DELAY	R/W	Numpad – value 0 onwards	Delay in seconds before executing the control due to low or high flow rates.
FLOW_CHECK_DELAY	R/W	Numpad – value 0 onwards	Delay in seconds after the start of the pump before monitoring the flow rates.
PROFILE_CTRL	R/W	Numpad – value 0 to 2	0 – profile protection disabled. 1 – PID deviation, generates alarm , PROFILE HIGH, if PID deviation exceeds PROFILE_LIMIT. 2 – PID output, generates alarm , PROFILE HIGH, if PID output exceeds PROFILE_LIMIT.
PROFILE_LIMIT	R/W	Numpad – value 0 to 32767	Value of profile protection limit.
PROFILE_CTRL_DELAY	R/W	Numpad – value 0 onwards	Time delay in seconds before the Profile Ctrl activates.
PRESSURE_ACT	R/W	Numpad – value 0.0 to 100.0	Actual pressure of the system.
FLOW_ACT	R/W	Numpad – value 0.0 to 100.0	Actual flow of the pump.
PID_DEVIATION	R/W	Numpad – value 0.0 to 100.0	PID deviation generated by PUMP_PID Function Block.
PID_OUT	R/W	Numpad – value 0.0 to 100.0	PID ouput generated by PUMP_PID Function Block.
DONE	R		Execution finished when output DONE = TRUE.
ERR	R		Error occurred during execution when output ERR = TRUE.
ENO	R		Error code.
