8 Communication via SIKONETZ5
8.1 Interface
RS485 interface
Available baud rates: 19.2 kBit / 57.6 kBit (Factory setting) / 115.2 kBit
No parity, 8 data bits, 1 stop bit, no handshake
8.2 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 as well as control and status words can be transferred between master and slave
by a single telegram exchange.
The parameter to be returned by the slave as a reply to the master's Write set point command
can be defined via the "Write set point reply parameter".
