FC 300 Design Guide RS-485 Installation and Set-up FC Protocol Message Framing Structure - FC 300 Content of a Character (byte) Each character transferred begins with a start bit. Then 8 data bits are transferred, corresponding to a byte. Each character is secured via a parity bit, which is set at "1" when it reaches parity (i.e. when there is an equal number of 1’s in the 8 data bits and the parity bit in total).
Page 278 The PKE field contains two sub-fields: Parameter command and response AK, and Parameter number PNU: Bits no. 12-15 transfer parameter commands from master to slave and return processed slave responses to the master. MG.33.B7.02 - VLT is a registered Danfoss trademark...
