ArmorStart with ArmorPoint ArmorStart for the ArmorPoint Backplane
The Bulletin 280/281A ArmorStart Distributed Motor Controller allows
connectivity to the ArmorPoint backplane. The ArmorPoint I/O system can
communicate using DeviceNet™, ControlNet™, or EtherNet
communication protocols. In addition to the other network communication
protocols; the ArmorPoint Distributed I/O products allow the I/O capability
to be expanded beyond the standard two outputs. Two dual-key relay output
connectors are provided as standard. The outputs are sourced from control
voltage power (A1 and A2). LED status indication is also provided, as
standard with the ArmorPoint. When using ArmorPoint, a maximum of two
ArmorStart Distributed Motor Controllers can be connected to the
ArmorPoint Distributed I/O products.
ArmorStart to ArmorPoint Connectivity
Figure 7 Connectivity Diagram for one ArmorStart Distributed Motor Controller
When connecting to the Bulletin 1738 ArmorPoint Distributed I/O product,
a network adapter and at least one ArmorPoint Digital Output, Digital Input,
Analog, AC and Relay product, or Specialty product must be selected. The
ArmorPoint Distributed I/O product can accommodate up to 63 modules per
network node. The cable that connects the ArmorPoint Distributed I/O to
the ArmorStart Distributed Motor Controller is the Bulletin 280A-EXT1.
The 280A-EXT1 includes an ArmorPoint bus extension cable and a
network terminating resistor. The network terminating resistor must be
connected to the “ArmorPoint Interface Out” connector.

If an additional ArmorStart Distributed Motor Controller is to be connected,
the Bulletin 280A-EXTCABLE will be required. A maximum of two
ArmorStart Distributed Motor Controllers can be connected to the Bulletin
1738 Distributed I/O. The Bulletin 280A-EXTCABLE is connected from
the “ArmorPoint Interface Out” on the first unit, to the “ArmorPoint
Interface In” on the second unit. The network terminating resistor is
connected to the “ArmorPoint Interface Out” on the second unit.
