The RJ-11 jack connects to a laptop computer for the following:

initial setup

configuration

troubleshooting

periodic maintenance

RS-485

The RS-485 port on the terminal blocks connects into industrial communications wiring and has the following advantages:

runs communications cable farther

allows multiple slave units on the network, addressed by P771 – Network Address

To communicate with equipment requiring RS-485 capability, Siemens Milltronics offers the RS-485 External Modem Kit. For more information, go to www.siemens.com/processautomation.

Modbus

The Modbus protocol is supported in the base unit and can be configured using the Communications parameters P770 to P782.

To set up communications with a Modbus RTU master device on port 2 using RS-485, set the following parameters:
