BMENOS0300 in RIO Drop of Standalone PAC in support of DIO Clouds

DIO Clouds

In this topology, the BMENOS0300 network option switch is used in place of a BMENOC0301/11 to reduce cost. The ports of the BMENOS0300 network option switch are used as follows:

The two network ports are configured as DIO Ports.

The service port is configured as an Access port, and supports an engineering tool (for example, Control Expert) resident on a PC.

CAUTION

RISK OF BROADCAST STORM

Do not connect an Ethernet device in one DIO cloud to an Ethernet device in another DIO cloud. Connecting these devices can result in the occurrence of a broadcast storm, which can overload the network and delay or prevent intended network communications.

Failure to follow these instructions can result in injury or equipment damage.

NOTE: Instead of a PC, a DIO cloud could be connected to the service port.
