   Select CANopen network baudrate from the available baudrate list (1 Mb/s, 500Kb/s, 250 Kb/s, 125Kb/s, 50Kb/s)
 Parametric Baudrate
   Baudrate is specified at runtime.
   Define an UDINT PLC variable and bind here.
   The value (bits/s) in of the variable at PLC startup will be used for network baudrate

 Master Settings
 Static Node ID
   Univoque network node id is assigned to Master in static way.
   Default value: 127. Allowed values: 1 to 127.
 Parametric Node ID
   Master node id is specified at runtime.
   Define an USINT PLC variable and bind here.
   The value in the variable at PLC startup (1 to 127) will be used as master node id.
