The inter-relay communication modules support high-speed, direct communication
Plus
between UR
-series devices. The direct inputs and outputs feature uses the
communication channels provided by these modules to exchange digital state
information. This feature is available on all UR
The communications channels are normally connected in a ring configuration as shown in
the following figure. The transmitter of one module is connected to the receiver of the next
module. The transmitter of this second module is then connected to the receiver of the
next module in the ring. This is continued to form a communications ring.
The interconnection for dual-channel communication modules is shown. Two channel
modules allow for a redundant ring configuration. That is, two rings can be created to
provide an additional independent data path. The required connections are: URPlus1-Tx1
to URPlus2-Rx1, URPlus2-Tx1 to URPlus3-Rx1, URPlus3-Tx1 to URPlus4-Rx1, and URPlus4-
Tx1 to URPlus1-Rx1 for the first ring; and URPlus1-Tx2 to URPlus4-Rx2, URPlus4-Tx2 to
URPlus3-Rx2, URPlus3-Tx2 to URPlus2-Rx2, and URPlus2-Tx2 to URPlus1-Rx2 for the
second ring.
