10 Communication via SIKONETZ5
10.1 Interface
Schnittstelle RS485
Available baud rates: 19.2 kBit / 57.6 kBit / 115.2 kBit
No parity, 8 data bits, 1 stop bit, no handshake
10.2 Data exchange
The protocol functions according to the master – slave principle.
The actuator acts as a slave. Every instance of communication must be initiated by the
master. When the master has sent a command telegram, the slave sends a reply telegram.
Broadcast commands are an exception, they remain always unanswered by the slave.
The protocol is optimized for cyclical data exchange. The relevant data such as set point and
actual value can be transferred between master and slave by a single telegram exchange.
