Field Bus Interface - Festo Compact Performance Series Programming And Diagnosis

1. Installation

1.4 Field bus interface

There are two plugs on the node for connecting the CP
system to the RIO net work. One of these connections
is for the incoming line, the other is for the continuing
line. The signal cables for both plugs are connected in-
ternally with each other.
Connecting – Looping the RIO cable from node to node. Both
variants
– Connecting the RIO cable by means of a T-adapter.
CAUTION
Branches (e.g. T-adapter) cause signal reflections,
under certain circumstances, if used with high baud
rates. This can lead to "telegram faults" with the
valves "failing" for short periods.
