2.1 Installing the RS485 interface
Profibus and Modbus use the same interface (RS485) for data
exchange.
We especially recommend the "Aufbaurichtlinie PROFIBUS/FMS",
published by the PROFIBUS user organization PNO, (PNO order num-
ber 2.111) with many practical tips for installation that also apply to
Modbus systems (
http://www.profibus.com/download/installa-
tion-guide/ ).
Further instructions for the installation and operation of a Modbus net-
work are availabe on the Internet under www.modbus.org.
Detailed information on the subject of PROFIBUS is given on the Inter-
net by the PROFIBUS user organization (PNO) under www.profi-
bus.com.
