Page 9: Communication
The CAN interface is connected using the CANH, CANL and REF (not mandatory) connections on the 9-pin connector. COMMUNICATION : eNod3-D can communicate using several protocols : - ModBus RTU - SCMBus standard format or fast format. - CANopen Switching from the SCMBus protocol to the ModBus-RTU protocol (and reciprocally) can be done by software programmation. -

Page 16: Dosing By Filling Functioning Mode
The filling functioning mode is a way to monitor a dosing cycle of a product by measuring the weight of a receptacle placed on a load cell. In this functioning mode, the dosing process is entirely managed by eNod3-D and especially thanks to its four digital outputs allowing to monitor the different phases of the cycle and to indicate errors. -

‘start delay’ has elapsed. It also causes an output assigned to the ‘cycle in progress’ function to be set. 17/23 eNod3-D : User’s instructions 165 752-A... -
Page 18: Cycle Description
11.2 Cycle description 11.2.1 Flow rate control (optional) eNod3-D includes a flow rate control system. It makes possible to check that the flow rate during the cycle is sufficient. The device controls that te flow rate remains equal or superior to a minimal value. If it is not the case, an output assigned to ‘dosing failure’... -
