Baud rate
•
Selection only for connection to a PC or Modbus. The following baud rates are allowed:
300 bit/s, 600 bit/s, 1200 bit/s, 2400 bit/s, 4800 bit/s, 9600 bit/s, 19200 bit/s, 38400 bit/s,
57600 bit/s, 115200 bit/s.
•
The baud rate of the Profibus is supported automatically up to 12 Mbit/s with the selection
being performed via the master station.
Note
The Baud rate is selected during parameterization (using SICAM P Par or the display). It can be
set in the range between 300 bit/s and 115200 bit/s, for the IEC 60870-5-103 protocol, however,
only in the range between 9600 bit/s and 38400 bit/s.
Parity
•
Only for Modbus (N = None, E = Even, O = Odd)
Protocol
•
SICAM P ASCII Protocol: PC RS485 (for connection to a PC via programming software)
•
Profibus DP (with firmware version V3 only) or
IEC 60870-5-103 (with firmware version V4 only)
•
Modbus RTU
•
