Pump Controlling Device That Obtains Parameter Values From Insulin Pump For Executing Functions

A method of operating an insulin treatment system that includes an insulin pump and a pump controlling device, wherein the pump controlling device communicates with the insulin pump for obtaining parameter values for executing functions, the method comprising:

• receiving, by the pump controlling device, a request to execute a function related to delivery of a bolus insulin dosage function, the function being included on the pump and the pump controlling device, the function being governed by a rule, the rule limiting bolus insulin delivery up to a maximum bolus dosage, a value for the maximum bolus dosage included on the pump;
• establishing communication between the pump controlling device and the insulin pump;
• requesting, by the pump controlling device, the value for the maximum bolus dosage from the insulin pump;
• receiving, by the insulin pump, the request for the value for the maximum bolus dosage from the pump controlling device;
• sending, by the insulin pump, the value for the maximum bolus dosage to the pump controlling device;
• receiving, by the pump controlling device, the value for the maximum bolus dosage from the insulin pump;
• and
• executing, by the pump controlling device, the function using the received value for the maximum bolus dosage.
