Address
A prerequisite for the configuration of the AnyBus-S Modbus RTU
Modbus module is the setting of its address. The setting of the address
is carried out with the dip switches, 1-7 (1). Each switch sets the value
0 or 1 for one digit of the seven-digit binary number. This enables
addresses of 0-127 to be set.
Examples:
Baud rate
A prerequisite for the configuration of the AnyBus-S Modbus RTU
Modbus module is the setting of the baud rate. The setting of the baud
rate is carried out with the dip switches, 8,1,2 (2). Each switch sets the
value 0 or 1 for one digit of the three-digit binary number. This makes
seven valid settings possible.
Parity
A prerequisite for the configuration of the AnyBus-S Modbus RTU
Modbus module is the setting of the parity. The setting of the parity is
carried out with the parity dip switches, 3,4 (3). Each switch sets the
value 0 or 1 for one digit of the two-digit binary number. This makes
three valid settings possible.
