RS-485 Operating Mode

Figure 14: Bus Connection RS-485 Operating Mode, Half-Duplex

In the RS-485 operating mode (bus connection), a twisted-pair cable should be

used at least for larger cable lengths or higher transmission rates. The ends of the

cable should be terminated with a terminal resistor.

Generally, a passive resistance is used by connecting the signal lines via one

100

… 120

resistor apiece to both bus ends.

For communication between 2 or more 750-652/040-000 interface modules at low

baud rates or with shorter line lengths, it is not necessary to use the terminal

resistors.

The receiver built into the I/O module has a defined output state if both inputs are

not connected and the data line has a short circuit or no transmitter is active (idle

line).

If the 750-652/040-000 serial interface module works on a network with other

communication partners, the wiring of a resistance-biasing network (known as a

fail-safe network) to one line end can be necessary.
