Operating Instructions REOVIB MFS 268 - RS 232 Interface Programming ELEKTRONIK 1.0 General The REOVIB MFS 268 range of controllers for vibratory feeders can be operated from an RS 232 interface. To do this the frequency controller must be set up to receive serial data, using Menu “C 017” (S.I.F.
Operating Instructions REOVIB MFS 268 - RS 232 Interface Programming ELEKTRONIK The serial interface information is sent as a character string that is closed with a RETURN (CR) for synchronization. Within the string there are three used data words each having four characters (Bytes).
Operating Instructions REOVIB MFS 268 - RS 232 Interface Programming ELEKTRONIK 3.1 Normal operation In normal operation the serial interface is used to adjust the set point for the feeder throughput and the digital control signals e.g. the enable. The unit status (ready or fault) is reported. All data words are in the range 0000..FFFF H.
Operating Instructions REOVIB MFS 268 - RS 232 Interface Programming ELEKTRONIK 3.2 Parameter operation The unit specific parameters can be read and changed in Parameter Operation. Before writing parameters a write enable must be sent. Then it is possible to change a single or several parameters.
