A control system for a cold planer having a conveyor configured to transfer material into a first receptacle is disclosed. The control system may include a first sensor configured to generate a first signal indicative of an amount of material being transferred into the first receptacle, a communication device configured to transfer information between the cold planer and the first receptacle, and a controller electronically connected to the first sensor and the communication device. The controller may be configured to receive an input from the first receptacle via the communication device and determine a fill level of the first receptacle based on the first signal and the input from the first receptacle.
