AN-X-MOD (Master) Module Overview
The AN-X-MOD (Master) communications module connects a
ControlLogix PLC or other device to a Modicon S908 remote I/O
network, over Ethernet.
The module acts as a scanner on the S908 network, reading inputs and
writing outputs. The module supports 800 series and Quantum remote
drops. It supports up to 32 drops.
The module supports up to 16 scheduled connections with a
ControlLogix processor, over Ethernet, so the ControlLogix processor
can read inputs from the Modicon network and write outputs.
The AN-X-MOD (Master) module has a web interface for configuration.
You can communicate with the module using any standard web browser
such as Internet Explorer.
A watchdog timer is implemented in the module’s hardware. If the
firmware does not kick the watchdog within the timeout period the
watchdog times out and places the module into a safe fatal failure state.
A jabber inhibit timer is implemented in the module’s hardware. If the
network transmitter is on longer than 150% of the longest network frame
time, the transmitter is forced off and the module is placed into a safe
fatal failure state.
