The signal wires (A, B) have to be twisted. GND (C/X) can be connected via a wire or via the cable
screen. In disturbed environments shielded cables must be used. Supply resistors (Rs) have to be present
in bus master (PC) interface. Stubs should be avoided when connecting the devices. A pure line network
is ideal.
You may connect up to 32 Modbus devices to the bus. A proper operation requires that all devices
connected to the bus have equal communication settings (baud rate, transmission format) and unique
Modbus addresses.
The bus system is operated half duplex and may be extended to a maximum length of 1200 m without
repeater.
