AN-X2-MOD-MON Module Overview
The AN-X2-MOD-MON communications module connects a ControlLogix PLC or other
device to a Modicon S908 remote I/O network, over Ethernet.
The module monitors inputs and outputs on the S908 network. The module supports 800
series and Quantum remote drops. It supports up to 32 drops. In monitor mode, the
AN-X2-MOD-MON never transmits on the Modicon network.
The module supports scheduled connections with a ControlLogix processor, over
Ethernet, so the ControlLogix processor can read inputs and outputs from the Modicon
network.
Both the S908 and ControlLogix configurations can be generated automatically by the
AN-X from data captured from the S908 network.
The AN-X-MOD-MON module has a web interface for configuration. You can
communicate with the module using any standard web browser such as Internet Explorer.
The module firmware can be updated using the web interface. Refer to page 53 for
details.
As an Upgrade Tool
This module is primarily intended for users who are planning to upgrade a system from a
Modicon controller to a ControlLogix with an AN-X2-MOD-MAS acting as the master
on the Modicon network. With an AN-X-MOD-MON, the ControlLogix can monitor
live inputs and outputs on the existing system and compare the outputs from the
replacement system to those from the existing system. When you are satisfied that the
replacement system operates exactly like the existing system, you can install the upgrade.
The AN-X2-MOD-MON uses the same hardware as the AN-X2-MOD-MAS. You
simply have to select different firmware using the web interface.
