Overview
The FP-1000 is a network module for the FieldPoint system. It
provides connection to an RS-232 network using a simple ASCII
protocol. In addition, it has an isolated RS-485 repeater built in to
transparently add up to 24 FP-1001 network modules to the same
host computer serial port.
This document provides a quick guide to installing and configuring
the FP-1000 network module. For more detailed information on
using the network module, refer to the FP-1000/1001 user manual.
For information on the ASCII protocol used by the network
module, refer to the FP-1000/1001 programmer reference manual.

  • Page 2: Din Rail Mounting

    DIN Rail Mounting NOTE: Terminal bases must be connected to the network module before applying power to the module. Do not connect or disconnect terminal bases while power is applied to the network module. The FP-1000 has a simple rail clip for mounting reliably onto a standard 35 mm DIN rail.

    4. Add terminal bases to the DIN rail with their local bus connectors firmly mated to the FP-1000 local bus connector. The FP-1000 is shipped with a protective cover over the local bus connector. Remove this protective cover, and place it over the local bus connector of the last terminal base in the stack.

    Powering the FP-1000 NOTE: Terminal bases must be connected to the FP-1000, and the baud rate switch must be set, before power is applied to the FP-1000. An 11-30 VDC power supply is required by each FieldPoint stack. The network module filters and regulates this supplied power and provides power for all the I/O modules in the stack.
